SIBA trapping

World Record in Optical Nanotweezers That was the heading for the latest news in manipulation of nano-sized particles achieved by a team led by ICFO Group Leader and ICREA Professor Romain Quidant.

The research describes a novel approach to optically trapping nanoscale objects which enables to strongly relax the requirements on both the incident laser intensity and the laser intensity within the trap. The so-called “SIBA” method opens new opportunities for non-invasive immobilization of very small objects, such as single virus or quantum dots, whose damage thresholds lay way below the local intensity needed in other techniques.
