Keywords:azobenzene nanoparticles, water, local polarization

Optical deformation of azobenzene nanoparticles dispersed in water medium was investigated. The position and shape of nanoparticles were changed dependent on the distribution of local polarizations in optical near-fields formed by two cross propagating two evanescent waves.
