Photo-induced force microscopy enables nanoscale chemical imaging by detecting optically induced forces between a probe and a sample with sub-nanometre spatial resolution. Photo-induced force microscopy directly senses the light-induced dipolar force with uses in molecular nanoscopy, nanophotonics, polymer science, biology and surface chemistry.
