Engineers create optoelectronic tweezers to round up cells, microparticles
...tting diode has been used to trap more than 10,000 microparticles at the same time," said Ming Wu, UC Berkeley professor of electrical engineering and computer sciences and principal investigator of the study.

"We will stimulate individual cells with precisely coordinated biochemical and mechanical signals to quantify their dynamic response. Using multiple probes together, we will be able to measure cooperative effects in ce...Circulating endothelial microparticles lead to heart valve disease

... and the corresponding target is quantified. The microparticles are inexpensive because they can be produced efficiently in a single step. The design of the particles also makes the scanning devices cheaper.
