20 September 2012: We are currently updating the group website.


Ming Wu's group has recently developed a new image-driven optical manipulation tool called optoelectronic tweezers. Using light-induced dielectrophoresis on a photoconductor, virtual electrode pattern is generated by projecting an LED light through a DMD spatial light modulator. A single LED is capable of generating more than 15,000 individually addressable traps. The results was published in the July 21, 2005 issue of Nature titled,
"Massively Parallel Manipulation of Single Cells and Microparticles Using Optical Images".
