Synthesis of silver nanoparticles by gamma-ray irradiation in acetic water solution containing chitosan

摘要

Silver nanoparticles were synthesized by gamma-ray irradiation of acetic water solutions containing AghNO3 and chitosan.The resulting particles with the average diameter of 4-5 nm were densely dispersed in the solution due to the protection of chitosan chains.UV-vis spectra showed that the irradiation dose would affect the size distribution of nanoparticles.
