TL;DR: It is shown that optical forces can be used for the rapid (2–4 ms), active control of cell routing on a microfluidic chip and reduced complexity of the chip and simplify connectivity.

TL;DR: In this paper, a microfabricated fluorescence activated cell sorter based on an optical switch for rapid, active control of cell routing through a microfluidic channel network is presented.

TL;DR: In this article, a review of optical techniques used for micro-manipulation of small particles and cells in micro-fluidic devices is presented, based on the object's interaction with focused laser light (consequential forces of scattering and gradient).

TL;DR: Optophoresis as mentioned in this paper consists of subjecting particles to various optical forces, especially optical gradient forces, and more particularly moving optical gradients, so as to obtain useful results, which represents a practical approach to probing the inner workings of a living cell, preferably without any dyes, labels or other markers.

TL;DR: In this article, the use of vertical cavity surface emitting lasers (VCSELs) for optical trapping and active manipulation of live biological cells and microspheres was demonstrated using a 2-2 array of VCSEL arrays.
