Study results of the optical properties of nanoparticles of iron oxide, oxide bronzes in aqueous dispersion and biogels based on it are presented. It is shown that the oxide bronzes obtained by the methods of mechano-chemical and SHS synthesis can be used at the preparation of aqueous dispersion of the oxide bronze nanoparticles. These nanoparticles have stable optical properties, and their aqueous dispersions, so as the biogels based on it have no aggregation and sedimentation. By means of spectrometry of total absorption, it has been established that the absorption of bronze solution is generally determined by scattering of light in the visible side out of spectral band ~345—365 nm. This is confirmed by the dependency of optical density of the solutions on wave length. At the same time, the character of scattering of light is changed in dependence on size of the disperse particles. For the hydrogen molybdenum oxide bronze used as a photo absorbing addition to cartilage irradiated by laser, it was obtained ~five time higher photo thermal effect at the wave length of 1.56 μm, than for the iron oxide nanoparticles.
