| Abstract: | Au nanoparticles stabilized by chitosan have been prepared under the combined action of ultraviolet radiation and thermal exposure of its solutions doped with HAuCl4. With the use of absorption spectrophotometry and small-angle X-ray scattering, it has been shown that the use of chitosan of different molecular masses allows one to control both the sizes of Au particles and their aggregative stability in nanodispersions. |
