‘Repulsive’ Side To Light Force Could Control Nanodevices

A team of Yale University researchers has discovered a repulsive light force that can be used to control components on silicon microchips, meaning future nanodevices could be controlled by light rather than electricity. The team previously discovered an attractive force of light and showed how it could be manipulated to move components in semiconducting micro- and nano-electrical systems–tiny mechanical switches on a chip. The scientists have now uncovered a complementary repulsive force
