Green and rapid synthesis of cysteine-directed novel AgCu nanocluster hydrogel with good antibacterial activity

Because of the problem of bacterial resistance, inorganic antibacterial materials represented by metallic nanomaterials have attracted attention for their antimicrobial properties. However, their antibacterial efficiency and safety need to be improved, and the cost of preparation needs to be reduced. Here a novel and highly stable cysteine-directed silver-copper composite nanoclusters hydrogel (AgCu NCs hydrogel) was prepared by employing a...
