Light carrying photon momentum can push and pull microparticles through momentum exchange. This momentum exchange process generates optical forces, which either attracts (conventional optical tweezers ...

Atomic force microscopy is used to conduct single-asperity friction measurements at a water-graphite interface. Local mapping of the frictional force, which is based on the degree of the cantilever ...

Lateral optical forces induced by linearly polarized laser beams have been predicted to deflect dipolar particles with opposite chiralities toward opposite transversal directions. These ...
