MICROMANIPULATION OF MICROTOOLS MADE OF SU-8 BY INTEGRATED OPTICAL TWEEZERS

We propose a novel cell manipulation method of Integrated Optical Tweezers (IOT) with microtools made of negative photoresist, SU-8 (MicroChem). This microtool is made by photolithography and hence it has complex shape. IOT is a novel optical tweezers integrating Time-Shared Scanning (TSS) [1] for high speed manipulation of a few objects and Generalized Phase Contrast (GPC) [2] for trapping a lot of objects. Here we propose IOT as the combined manipulation method and demonstrate manipulation of SU-8 microtools. This proposed noncontact manipulation method worked well as we expected.
