    摘要: An optical measuring apparatus and method for analysis of samples contained in liquid drops provided by a liquid handling system has a liquid handling tip. A light source irradiates the liquid drop; a detector measures sample light; and an optics system with first optical elements transmits irradiation light, and a processor processes the measurement signals. The liquid drop is suspended at the liquid handling orifice of the liquid handling tip in a position where the liquid drop is penetrated by a first optical axis defined by the light source and the first optical elements. The liquid drop is physically touched only by the liquid handling tip and the liquid sample inside the liquid handling tip. A mutual adaption of the size and position of the liquid drop with respect to the first optical elements is achieved.

    摘要: A technique for shaping droplets is disclosed. Multiple optical traps, or at least one variable geometry trap, are used to deform a droplet. The surface tension of the droplet is lowered to be comparable with the force which can be applied using the optical traps, for example by using a surfactant such as Aerosol OT, with heptane droplets in a solution of sodium chloride. Solidification of deformed droplets can be achieved using polymerization.

    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 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.
