Original Abstract
tSilver nanoparticles (Ag-NPs) have been successfully prepared with a simple and green chemical reduction method. Triple helical schizophyllan (SPG) was used for the first time as reducing and stabilizingagents. The effect of temperature, silver nitrate/schizophyllan concentrations, pH of the reactions mediumand the reaction time were investigated. The obtained schizophyllan/Ag-NP was characterized by UV–visspectroscopy, TEM, DLS, X-ray diffraction, TGA, and ATR-FTIR. The results revealed that, Ag-NPs attachedto SPG through a strong non-covalent interaction, leading to good dispersion of Ag-NPs with a diameterof 6 nm within the biopolymer matrix. By increasing the pH of the reaction medium, the triple helicalstructure of SPG was partially broken. The SPG/AgNP nanocomposite was non-toxic for mouse fibroblastline (NIH-3T3) and human keratinocyte cell line (HaCaT).
