    • The invention is related to methods and apparatus that manipulate droplets in a microfluidic environment. Advantageously, embodiments of the invention manipulate droplets by controlling the electro-wetting characteristics of a surface with light, thereby inducing a gradient in the surface tension of a droplet. The gradient in the surface tension propels the droplet by capillary force. A variety of operations, such as transporting, joining, cutting, and creating can be performed. Advantageously, embodiments of the invention obviate the need to create a relatively large and complex control electrode array. A plurality of photoconductive cells or a layer of a photoconductive material selectively couples an electrode carrying an electrical bias to otherwise floating conductive cells in response to a beam of light. The electrical bias applied to the conductive cell generates a localized electric field, which can change the contact angle of the droplet, thereby permitting the droplet to be propelled.
    • 本发明涉及在微流体环境中操纵液滴的方法和装置。 有利地,本发明的实施例通过用光控制表面的电润湿特性来操纵液滴,由此引起液滴的表面张力的梯度。 表面张力的梯度通过毛细管力推动液滴。 可以进行各种操作,例如运输,连接,切割和创建。 有利地,本发明的实施例消除了产生相对较大和复杂的控制电极阵列的需要。 响应于光束,多个光电导电池或光电导材料层将携带电偏压的电极选择性地耦合到另外的浮动导电单元。 施加到导电电池的电偏压产生局部电场,这可以改变液滴的接触角,从而允许液滴被推进。

    • An optical image-driven light induced dielectrophoresis (DEP) apparatus and method are described which provide for the manipulation of particles or cells with a diameter on the order of 100 μm or less. The apparatus is referred to as optoelectric tweezers (OET) and provides a number of advantages over conventional optical tweezers, in particular the ability to perform operations in parallel and over a large area without damage to living cells. The OET device generally comprises a planar liquid-filled structure having one or more portions which are photoconductive to convert incoming light to a change in the electric field pattern. The light patterns are dynamically generated to provide a number of manipulation structures that can manipulate single particles and cells or groups of particles/cells. The OET preferably includes a microscopic imaging means to provide feedback for the optical manipulation, such as detecting position and characteristics wherein the light patterns are modulated accordingly.

    • A single-sided continuous optoelectrowetting (SCOEW) device for manipulating droplets retained in a fluid over the SCOEW device with dynamic patterns of low intensity light, such as from a display screen, is described. A single pair of lateral electrodes are utilized for providing a lateral electric field bias, with transport motion controlled in response to projecting light through a photoconductive layer and dielectric layer adjacent to which droplets are retained. The device is configured for optically manipulating droplets having volumes spanning over five orders of magnitude, and can be configured to perform droplet dispensing, transport, splitting, merging, mixing and other droplet manipulation functions involving any of the above on a single sided surface.
