Physical and biological synthesis of GNPs and keratin nanoparticles from chicken’s feather and applications

Abstract In this paper, we aim to synthesize keratin nanoparticles from chicken’s feather. Crude keratin was extracted by chemical method. We obtained results for keratin nanoparticles using glutaraldehyde as a cross-linking agent. In this study, gold nanoparticles (GNps prepared by way Laser Ablation) with keratin nanoparticles for the production of antibacterial materials. NPs samples were characterized using a Transmission Electron Microscope (TEM). The absorption spectra were measure by UV-Visible, double beam spectrophotometer. Three types of pathogenic bacteria were used in this study (Pseudomonas aeruginosa, Staphylococcus aureus, and E. coli) in addition to one opportunistic yeast (Candida albicans). Nano-creatine particles can be used for wound dressing as well as cosmetic preparation.
