Highly stable dispersions of nanosized copper （Cu） particles with an average size of （2.6 ± 0.5） nm were synthesized by in situ reduction of Cu（II） to immobilize Cu nanoparticles on the amino-enriched surfa...Highly stable dispersions of nanosized copper （Cu） particles with an average size of （2.6 ± 0.5） nm were synthesized by in situ reduction of Cu（II） to immobilize Cu nanoparticles on the amino-enriched surface of chitosan （CTS）. The synthetic process and stability of the L-ascorbic acid-stabilized Cu-CTS nanocomposites were investigated by X-ray photoelectron spectroscopy and Fourier transform Infrared spectroscopy. The antimicrobial efficiency and potency of the Cu-CTS nanocomposites were studied. The Cu-CTS nanocomposites were found to exhibit a broad antimicrobial spectrum and high antimicrobial activity against Gram-positive bacterial pathogen Staphylococcus aureus and fungal pathogen Monilia albican. The minimum inhibitory concentration of the Cu-CTS nanocomposites toward S. aureus was found to be 6.4 μg mL^-1, much lower than those reported in the literature. Furthermore, the Cu-CTS nanocomposites were stable and main- tained good disinfection potential even after 90-day shelf-time under ambient conditions.展开更多
