An international team of researchers (South Africa, USA – MIT) has built and demonstrated a vector holographic optical trapping and tweezing system which allows micrometer sized particles, such as biological cells, to be captured and manipulated only with light. They showed how to create and control any pattern of light holographically, and then used this to form a new optical trapping and tweezing device. The device can work with both the traditional laser beams as well as more complex vector beams. The new device can be useful in single cell studies in biology and medicine, small volume chemical reactions, fundamental physics and for future on-chip devices…read more.
