Antibacterial activities of a novel Cu-bearing high-entropy alloy against multi-drug-resistant Acinetobacter baumannii and Staphylococcus aureus

Acinetobacter baumannii and methicillin-resistant Staphylococcus aureus (MRSA) are two prevalent pathogens and have developed high resistant to most antibiotics. Therefore, it is a pressing need to develop a new method to inhibit the spread of drug-resistant bacteria. Copper containing high-entropy alloy (HEA, Al0.4CoCrCuFeNi) is a new kind of alloy material, which shows extensive antibacterial activity and mechanical properties in our previous...
