Abstract: 

This work was devoted to the study of the photothermal and photochemical processes occurring under laser irradiation of the nano-systems consisting of gold nanoparticles incorporated into polymer nano-carriers in a non-ionic and anionic form. The UV-vis spectroscopy demonstrated that the intensity of the surface plasmon resonance band is higher for the nano-system synthesized in an anionic polymer; this indicates a slightly larger number of for med nanoparticles. Holographic interferometry in real time didn't register a drastic difference in the behavior of Au sols synthesized in non-ionic and anionic polymer matrices. However, a local heating process took place under the irradiation of both Au sols.
