Optical microscopy for nanoparticles temperature and velocity field visualization

The technique of nanoparticles dynamics studies based on selective plane illumination microscopy and statistical particle tracking velocimetry has been developed. It allows for the visualization of water suspended gold nanoparticles dynamics. Distribution of particles temperature and velocity of their ordered motion could be obtained with spatial resolution of several micrometers. The proposed technique could be used for the studies of photothermal and photophorethic effects induced by laser irradiation in colloidal systems.
