摘要

Janus particles containing chitosan and silver were synthesized in an eco-friendly manner and were confirmed using transmission electron microscopy. Based on the data of the antimicrobial activity assessment, this material exhibited a higher antimicrobial activity than virgin chitosan with long lasting antibacterial effectiveness against Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Salmonella choleraesuis bacteria, as well as Botrytis cinerea fungi. The results showed that the Janus polymer could completely suppress the growth and germination of B. cinerea at a concentration of 0.02 mg/mL in vitro and in vivo. This Janus polymer is an advanced functional material that combines the suitable properties of both components and could be an alternative new antimicrobial agent due to its unique chemical properties and pronounced antimicrobial activity. This material is a potential candidate for use in the food industry to prevent microbial contamination and to inhibit the growth of microorganisms, enhancing product quality and, extend shelf-life of fresh and processed agri-food products.
