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...

Cells are the basic element in humans, animals and plants. As they are so tiny, the manipulation of these small matters is impossible with humans’ hands and we cannot even see them with bare eyes. In this video, I am going to bring you into a microfluidic device; the place where cells and particles can be manipulated by conducting PDMS. This is a simple PDMS-based microfluidic device with two inlets and two outlets. But what make it interesting is conducting PDMS electrodes embedded...
