摘要： 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 group 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.
摘要翻译：描述了一种光学图像驱动的光诱导介电电泳（DEP）装置和方法，其提供对具有大约100μm或更小的直径的颗粒或细胞的操纵。该设备被称为光电镊子（OET），并且提供了许多优于常规光学镊子的优点，特别是并行地和大面积地进行操作而不损坏活细胞的能力。 OET装置通常包括具有一个或多个光电导体部分的平面液体填充结构，以将入射光转换成电场图案的变化。光图案被动态地产生以提供可以操纵单个颗粒和细胞或一组颗粒/细胞的多个操纵结构。 OET优选地包括用于为光学操作提供反馈的微观成像装置，例如检测位置和特性，其中相应地调制光图案。

摘要： 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.
