This is a video by a team from the QMEMS Lab in the National Tsing Hua University, Taiwan. This video is based on an accepted paper of BMF, entitled “Cell rotation using optoelectronic tweezers.” The authors are Y.-L. Liang, Y.-P. Huang, Y.-S. Lu, Max T. Hou and J. Andrew Yeh. It is submitted as an entrant for the BMF Video Contest: Small Matters.

This video explains a rotation method by using OET devices. In this method, the configuration of the optoelectronic tweezers (OET) is not changed. The cell can be rotated by a rotating electric field which is innately generated by the typical OET device. Controlling the virtual electrodes generated by the illuminated patterns, the cell can be two-dimensionally moved and rotated about its pitch axis. The electrorotation of cells by OET is very promising for a wide variety of cell manipulation applications.
