APPARATUS AND METHOD FOR TRANSPORT OF MICROSCOPIC OBJECT(S)

摘要

A system and the method for transport of microscopic objects/particles involving the use of laser source operatively connected to a microscope objective which is adapted to generate optical focal spots on said particle(s) with asymmetric intensity profile in transverse plane followed by varying the said asymmetry of the gradient optical forces on the micron sized object/particles to thereby transport the microscopic object(s). The system and the method can be used to transport microscopic objects including i) transportation of cells and intra-cellular organelles, ii) acceleration of microscopic objects along any direction in a plane transverse to the direction of propagation of laser beam, iii) optical channeling of objects through a micro-capillary from one micro-well to another and transfer to another channel after desired processing, iv) sorting of microscopic objects, v) optical control of micro-machines, micro-fluidic devices etc.
