Huang, Nay Ming and Radiman, Shahidan and Lim, Hong Ngee and Khiew, Poi Sim and Chiu, Wee Siong and Tan, Thian Khoon and Ahmad, Azizan and Idris, H. (2008) Facile synthesis of silver nanoparticles under γ-irradiation: effect of chitosan concentration. In: International Conference on Nanoscience and Nanotechnology (NANO-SciTech 2008), 18-21 Nov. 2008, Shah Alam, Selangor. (pp. 191-195).


In the present study, a biopolymer, low molecular weight chitosan had been utilized as a “green” stabilizing agent for the synthesis of silver nanoparticles under γ‐irradiation. The as‐synthesized silver nanoparticles have particle diameters in the range of 5 nm–30 nm depending on the percentage of chitosan used (0.1 wt%, 0.5 wt%, 1.0 wt% & 2.0 wt%). It was found that the yield of the silver nanoparticles was in accordance with the concentration of chitosan presence in the solution due to the reduction by the chitosan radical during irradiation. The highly stable chitosan encapsulated silver nanoparticles were characterized using transmission electron microscopy (TEM), UV‐Visible spectrophotometer (UV‐VIS) and X‐ray diffraction spectroscopy (XRD).
