I will review some of the techniques most often employed, namely the photonic force microscope (PFM) and the total internal reflection microscope (TIRM), which are able to measure tiny forces acting on optically trapped particles. I will then discuss several applications of such nanoscopic forces: from plasmonic optical manipulation, to self-propelled microswimmers, to self-organization in large ensembles of particles.EnglishBrownian motionForceNanoscienceOptical tweezersPhotonic force microscopePlasmonicsTorqueTotal internal reflection microscopyConference Paper10.1117/12.929409
