The SyncMaster 570v"s good performance and rock-bottom price make it shine. If you"re shopping for a 15-inch display for everyday use, this sleek solution won"t disappoint.

The unit"s easy-to-use onscreen menu system was a cinch. You can greatly improve the SyncMaster 570v"s out-of-box settings by carefully adjusting the fine and course phase rates. The SyncMaster"s auto-adjust button will fine-tune your settings in an instant, and you"ll be hard-pressed to improve upon the picture with further tweaks. Although this basic LCD monitor is short on fluffy features, Samsung does offer an optional USB hub with four powered downstream ports for $31.

On the downside, the 570v"s slow 45ms pixel-refresh rate created a ghostlike trail behind moving images (such as DVD movies). Those interested in better multimedia performance should check out KDS"s Rad-5, which has a faster rating (25ms). That said, multimedia enthusiasts usually prefer standard CRT monitors for their superior refresh rates.

The SyncMaster 570v has a three-year warranty on parts and labor, and Samsung provides toll-free technical support 24 hours a day, 365 days a year. From July 1, 2001 to September 30, 2001, Samsung is offering a rebate that brings down the unit"s already low price to $399.

The 570v"s crisp, well-saturated picture exceeded our expectations. The screen"s viewing angle is tight (120 degrees horizontally, 110 degrees vertically) but near the average for its class.

Further, in some embodiments, the dielectric assembly of a device described herein has an effective capacitance of about 10 μF/m2to about 10,000 μF/m2, about 10 μF/m2to about 5000 μF/m2, about 10 μF/m2to about 1000 μF/m2, about 30 μF/m2to about 500 μF/m2, or about 50 μF/m2to about 500 μF/m2. In some embodiments, the dielectric assembly of a device described herein has an effective capacitance of about 10 μF/m2to about 100 μF/m2, about 30 μF/m2to about 300 μF/m2, or about 30 μF/m2to about 150 μF/m2. The effective capacitance of a dielectric assembly described herein can be measured or calculated in any manner not inconsistent with the objectives of the present invention. For example, when the dielectric assembly comprises multiple layers including a first hydrophobic dielectric material layer and a second dielectric material layer, the effective capacitance can be expressed according to equation (1):

In some embodiments, a single-sided microfluidic device described herein further comprises a radiation source. Such a single-sided microfluidic device, in some embodiments, can have a low threshold voltage. The threshold voltage of a device, for reference purposes herein, can be the lowest voltage at which droplet motion or translation on the plane of the hydrophobic dielectric layer of the device is observed. Moreover, the threshold voltage can be a direct current (DC) voltage. It is also possible for a threshold voltage described herein to be an alternating current (AC) voltage. In some embodiments, a single-sided device described herein can have a threshold voltage of less than 1 kV (DC), less than about 600 V (DC), or less than about 100 V (DC). In some embodiments, a single-sided device described herein has a threshold voltage between about 10 V (DC) and about 1000 V (DC), between about 30 V (DC) and about 600 V (DC), between about 50 V (DC) and about 600 V (DC), or between about 50 V (DC) and about 150 V (DC).

Further, in some instances, a single-sided device can have a threshold voltage recited herein when the radiation source provides radiation at an intensity of less than about 4000 lumens, less than about 3600 lumens, less than about 500 cd/m2, less than about 400 cd/m2, less than about 350 cd/m2, less than about 300 cd/m2. A lumen (lm), for reference purposes herein, can in some cases be an “ANSI” lumen (measured as defined in the document IT7.215 (1992)). In some embodiments, a device described herein exhibits a threshold voltage of about 50 V (DC) to about 600 V (DC) at an illumination intensity between about 1000 lm and about 4000 lm, between about 1000 lm and about 3800 lm, between about 2000 lm and about 4000 lm, between about 2500 lm and about 4000 lm, or between about 2500 lm and about 3800 lm. In other embodiments, a device described herein exhibits a threshold voltage of about 40 V (DC) to about 600 V (DC) at an illumination intensity between about 50 cd/m2and about 500 cd/m2, between about 50 cd/m2and about 400 cd/m2, between about 100 cd/m2and about 400 cd/m2, between about 150 cd/m2and about 350 cd/m2, or between about 200 cd/m2and about 400 cd/m2.

Moreover, in some instances, the ratio of the radius of a droplet of liquid disposed on the hydrophobic surface to a width of an image projected onto the photoconductive layer is between about 0.67 and about 2.0 or between about 0.85 and about 1.5. In some embodiments, the ratio of the radius of the droplet to a width of the image is between about 0.9 and about 1.3, between about 0.9 and about 1.2, or between about 0.95 and about 1.15.

Turning now to components of devices, single-sided microfluidic devices described herein comprise a substrate. Any substrate not inconsistent with the objectives of the present invention may be used. In some embodiments, a substrate is radiation transmissive. A radiation transmissive substrate, in some embodiments, transmits rather than reflects or absorbs radiation of a desired wavelength. For example, in some embodiments, a radiation transmissive substrate exhibits optical transparency in the visible region of the electromagnetic spectrum, such as between 450 nm and 750 nm. In some embodiments, a radiation transmissive substrate exhibits optical transparency in the infrared (IR) region of the electromagnetic spectrum, including in one or more of the near-IR (NIR, 750 nm-1.4 μm), short-wavelength IR (SWIR, 1.4-3 μm), mid-wavelength IR (MWIR, 3-8 μm), and long-wavelength IR (LWIR, 8-15 μm). In some embodiments, a radiation transmissive substrate exhibits optical transparency in the ultraviolet (UV) region of the electromagnetic spectrum, including in one or more of the Ultraviolet A (UVA, 315-400 nm), Ultraviolet B (UVB, 280-315 nm), and Ultraviolet C (UVC, 100-280 nm). Optical transparency in a region described herein can comprise an optical transparency of at least about 60 percent, at least about 70 percent, at least about 80 percent, at least about 90, or at least about 95 percent in the region, such as between 450 nm and 750 nm or between 750 nm and 1.4 gm. In some embodiments, the radiation transmission profile of a substrate described herein is selected based on a radiation absorption profile of a photoconductive layer of the device. In some cases, for instance, a substrate is chosen to permit the transmission of radiation that can be absorbed by the photoconductive layer, thus providing optoelectric activation of the device.

A dielectric assembly described herein, in some embodiments, has an effective capacitance of about 10 μF/m2to about 10,000 μF/m2, as described by equation (1) above. In some cases, a dielectric assembly has an effective capacitance of about 10 μF/m2to about 5000 μF/m2, about 10 μF/m2to about 1000 μF/m2, about 50 μF/m2to about 500 μF/m2, about 100 μF/m2to about 1000 μF/m2, about 100 μF/m2to about 500 μF/m2, about 200 μF/m2to about 1000 μF/m2, or about 500 μF/m2to about 1000 μF/m2, as described by equation (1). In some instances, a dielectric assembly has an effective capacitance of about 10 μF/m2to about 300 μF/m2, about 30 μF/m2to about 150 μF/m2, or about 30 μF/m2to about 100 μF/m2, as described by equation (1).

In addition, in some embodiments, a dielectric assembly having an effective capacitance recited herein also has a reduced thickness compared to other dielectric assemblies. For example, in some embodiments, a dielectric assembly having an effective capacitance of about 10 μf/m2to about 1000 μF/m2has a total average thickness between about 20 nm and about 2000 nm, between about 20 nm and about 1500 nm, between about 30 nm and about 1300 nm, between about 50 nm and about 2000 nm, between about 50 nm and about 1000 nm, between about 100 nm and about 1500 nm, between about 100 nm and about 500 nm, between about 500 nm and about 2000 nm, or between about 500 nm and about 1500 nm. A microfluidic device comprising such a dielectric assembly, in some embodiments, can exhibit a reduced threshold voltage and/or higher droplet transport speeds, including at low illumination intensity.

A dielectric assembly of a microfluidic device described herein can also comprise multiple layers. In some embodiments comprising multiple layers, at least two layers of the dielectric assembly are formed from different dielectric materials. For example, in some embodiments, at least one layer of the dielectric assembly is formed from a hydrophobic first dielectric material and at least one layer of the dielectric assembly is formed from a second dielectric material having a dielectric constant of at least about 3, at least about 5, or at least about 7. In some embodiments, a second dielectric material has a dielectric constant between about 3 and about 27, between about 3 and about 15, between about 5 and about 12, between about 5 and about 10, or between about 7 and about 10. A second dielectric material can be hydrophobic or hydrophilic.

In addition, when a dielectric assembly comprises multiple layers, the layers can have any thicknesses not inconsistent with the objectives of the present invention. For example, in one exemplary embodiment, a layer formed from a hydrophobic first dielectric material has an average thickness between about 10 nm and about 1700 nm and a layer formed from a second dielectric material having a dielectric constant of at least about 3 or at least about 5 has an average thickness between about 10 nm and about 200 nm. In other embodiments, a layer formed from a hydrophobic first dielectric material has an average thickness between about 20 nm and about 1700 nm, between about 30 nm and about 1500 nm, between about 50 nm and about 500 nm, between about 50 nm and about 300 nm, or between about 150 nm and about 350 nm and a layer formed from a second dielectric material having a dielectric constant of at least about 3 or at least about 5 has an average thickness between about 10 nm and about 50 nm, between about 10 n m and about 90 nm, between about 20 nm and about 150 nm, between about 30 nm and about 100 nm, or between about 50 nm and about 200 nm. Further, in some embodiments, a dielectric assembly has a total average thickness between about 20 nm and about 2000 nm.

Single-sided microfluidic devices described herein, in some embodiments, also comprise a radiation source. Any radiation source not inconsistent with the objectives of the present invention may be used. In some embodiments, for instance, the radiation source is a flat panel display such as a liquid crystal display (LCD) or optoelectronic screen. A flat panel display, in some embodiments, is a laptop computer screen or a tablet computer screen such as an iPad or Android tablet screen. In other embodiments, the flat panel display comprises a screen of a wireless communication device such as a mobile phone. In some cases, the radiation source is a data projector.

Moreover, in some embodiments, a radiation source described herein provides an illumination intensity between about 1000 lm and about 4000 lm, between about 1000 lm and about 3800 lm, between about 2000 lm and about 4000 lm, between about 2500 lm and about 4000 lm, or between about 2500 lm and about 3800 lm, based on the illuminated area of the photoconductive layer. In some embodiments, a radiation source provides an illumination intensity between about 50 cd/m2and about 500 cd/m2, between about 50 cd/m2and about 400 cd/m2, between about 100 cd/m2and about 400 cd/m2, between about 150 cd/m2and about 350 cd/m2, or between about 200 cd/m2and about 400 cd/m2. Additionally, in some cases, a radiation source provides radiation in the visible region of the electromagnetic spectrum, such as between 450 nm and 750 nm. In some embodiments, a radiation source provides radiation in the infrared (IR) region of the electromagnetic spectrum, including in one or more of the near-IR (NIR, 750 nm-1.4 μm), short-wavelength IR (SWIR, 1.4-3 μm), mid-wavelength IR (MWIR, 3-8 μm), and long-wavelength IR (LWIR, 8-15 μm). In some embodiments, a radiation source provides radiation in the ultraviolet (UV) region of the electromagnetic spectrum, including in one or more of the Ultraviolet A (UVA, 315-400 nm), Ultraviolet B (UVB, 280-315 nm), and Ultraviolet C (UVC, 100-280 nm).

In addition, the microfluidic device (100) of FIG. 1 further comprises electrical contacts (150) formed from gold and chromium. The electrical contacts (150) are in electrical communication with the photoconductive layer (120). More specifically, in the embodiment of FIG. 1, the electrical contacts (150) are disposed on the photoconductive layer (120) and in electrical contact with the photoconductive layer (120).

In addition, an applied voltage described herein can have a small magnitude compared to some other devices. In some embodiments, for instance, a voltage of less than 1 kV (DC) is applied to the electrical contacts. In some embodiments, a voltage of less than about 600 V (DC), less than about 200 V (DC), or less than about 100 V (DC) is applied to the electrical contacts. In some embodiments, a voltage between about 10 V (DC) and about 1 kV (DC), between about 30 V (DC) and about 600 V (DC), or between about 50 V (DC) and about 150 V (DC) is applied to the electrical contacts. Further, in some embodiments, the magnitude of the applied voltage is selected based on the radiation source used to project an image onto the photoconductive layer. For example, in some embodiments wherein the radiation source is a data projector, a voltage of about 50 V is applied. In other embodiments wherein the radiation source is an optoelectronic screen, a voltage of about 600 V is applied.

Methods described herein also comprise projecting an image onto the photoconductive layer of a microfluidic device using a radiation source. Any radiation source not inconsistent with the objectives of the present invention may be used. In some embodiments, a radiation source comprises a radiation source described hereinabove in Section I. For example, in some embodiments, a radiation source is a flat panel display such as a liquid crystal display (LCD) or optoelectronic screen. A flat panel display can also be a laptop computer screen or a tablet computer screen such as an iPad screen. The flat panel display can also be a screen of a wireless communication device such as a mobile phone. In some embodiments, a radiation source is a data projector. Moreover, in some embodiments, a radiation source described herein provides an illumination intensity between about 2500 lm and about 4000 lm, based on the illuminated area of the photoconductive layer. In some embodiments, a radiation source provides an illumination intensity between about 100 cd/m2and about 400 cd/m2, based on the illuminated area of the photoconductive layer.

Moreover, in some instances, the ratio of the radius of the droplet of liquid to a width of an image projected onto the photoconductive layer is between about 0.67 and about 2.0 or between about 0.85 and about 1.5. In some embodiments, the ratio of the radius of the droplet to a width of the image is between about 0.9 and about 1.3, between about 0.9 and about 1.2, or between about 0.95 and about 1.15.

Moreover, in some embodiments, a droplet can be moved in any arbitrary direction on the xy-plane of the hydrophobic surface. Further, in some cases, a droplet can be moved in any arbitrary direction on the xy-plane at the same speed. In other words, the speed of droplet movement on the hydrophobic surface can be substantially independent of the direction of movement in the xy-plane. In some embodiments, a droplet is moved at a speed up to 20 mm/s or up to 15 mm/s. In some embodiments, a droplet is moved at a speed between about 3 mm/s and about 20 mm/s, between about 5 mm/s and about 15 mm/s, or between about 7 mm/s and about 12 mm/s. Moreover, in some instances, a droplet is moved at a speed described herein at an optical illumination and/or applied voltage or threshold voltage described herein. For example, in some embodiments, a droplet is moved at a speed of about 12 mm/s at an optical illumination of about 3500 lm and an applied voltage of about 120 V (DC). In other cases, a droplet is moved at a speed of about 1.2 mm/s at an optical illumination of about 336 cd/m2and an applied voltage of about 570 V (DC).

FIGS. 5(a)-(d) illustrate another series of plan views of a microfluidic device suitable for carrying out a method of moving a droplet described herein. As illustrated in FIG. 5(a), a 70-μL droplet of liquid (140) is disposed on a hydrophobic surface (131) of a dielectric assembly of a single-sided microfluidic device. The device of FIG. 5(a) has the same structure as the device of FIG. 4(a). In addition, the droplet movement illustrated in FIGS. 5(a)-(d) is carried out in a similar manner as the movement illustrated in FIGS. 4(a)-(c), except that in the embodiment of FIGS. 5(a)-(d), an image (170) is projected onto the surface (131) of the photoconductive layer of the device using an LCD screen instead of a data projector. FIGS. 5(b)-(d) illustrate the same image (170) and droplet (140) as in FIG. 5(a) after moving the image (170) and droplet (140) on the hydrophobic surface (131) using a JavaScript application. FIG. 5(a) illustrates the initial position of the droplet (140), and FIG. 5(d) illustrates the final position of the droplet (140). FIGS. 5(b) and 5(c) illustrate intermediate positions of the droplet (140). Again, the droplet movement illustrated in FIGS. 5(a)-(d) comprises multi-axis movement of the droplet.

Methods of reducing the drift of a droplet of liquid also comprise projecting an image onto a photoconductive layer of the microfluidic device with a radiation source. Any radiation source not inconsistent with the objectives of the present invention may be used. In some embodiments, a radiation source comprises a radiation source described hereinabove in Section I. For example, in some embodiments, a radiation source is a flat panel display such as a liquid crystal display (LCD) or optoelectronic screen.

Further, in some embodiments, an image overlaps the droplet of liquid an amount substantially equal to the radius of the droplet. In addition, an image projected as described herein can have any size and shape not inconsistent with the objectives of the present invention. For example, in some instances, an image has a shape configured to contain the droplet of liquid during movement of the droplet on the hydrophobic surface. In some embodiments, an image comprises a polygon or a curved shape. In some instances, an image comprises a shape formed from both curved lines and straight line segments or from the intersection or union of a polygon and a curved shape. Moreover, in some cases, an image comprises a hollow or “frame” shape, such as a rectangular, elliptical, or circular “picture frame” or “donut” type shape. In some embodiments, an image comprises a shape having a first leg, a second leg, and a third leg connecting the first and second legs. Further, in some cases, the first and second legs are substantially parallel to one another and the third leg is substantially perpendicular to the first and second legs. In some embodiments, an image described herein has a U-shape, H-shape or V-shape. Moreover, in some instances, the image overlaps the droplet between two aims of the U-shape, H-shape or V-shape. Additionally, in some embodiments, the ratio of the radius of the droplet of liquid to a width of an image projected onto the photoconductive layer is between about 0.67 and about 2.0 or between about 0.85 and about 1.5. In some embodiments, the ratio of the radius of the droplet to a width of the image is between about 0.9 and about 1.3, between about 0.9 and about 1.2, or between about 0.95 and about 1.15.

Next, a pattern of images was projected onto the photoconductive layer of the device using either a commercial data projector (Dell 4210X) or an LCD screen (TFT LCD screen, Samsung Galaxy Tab 10.1 tablet) as the radiation source. When the data projector was used, the projector was controlled using a personal computer. Images (5 mm wide) and illumination patterns were generated using a canvas-enabled JavaScript application. The patterns were controlled using mouse clicks and keyboard commands in the JavaScript file, as described above with reference to FIG. 8. Specifically, the size, shape, position, speed, and color of the images or illumination patterns were specified in the settings menu. The images or illumination patterns were drawn on the animation canvas based on the values input in the settings menu. The images or patterns could be moved anywhere in the animation canvas using mouse clicks.
