Contamination of food by bacterial pathogens is one of the biggest concerns in the food industry as it can result in serious human illnesses and death. Approaches to eliminate bacteria from outer surfaces of food products would be an effective way to safeguard against bacterial contamination. Nanopillars found on natural surfaces have been shown to mechanically damage cell membranes of foodborne bacteria. Therefore, fabricating bio-inspired mechano-bactericidal nanostructures into food packaging and processing materials could be a promising strategy to reduce surface bacterial contamination, to improve food safety. In this review, we summarize the formation of natural and synthetic nanopillared surfaces and their mechanism of action, and highlight the factors that influence their mechano-bactericidal activities.

受生物启发的机械杀菌纳米结构:消除表面食源性细菌的一种有前途的策略

细菌病原体污染食品是食品工业中最大的担忧之一,因为它可能导致严重的人类疾病和死亡。消除食品外表面细菌的方法将是防止细菌污染的有效方法。已发现在自然表面上发现的纳米柱会机械破坏食源性细菌的细胞膜。因此,将生物启发的机械杀菌纳米结构制作到食品包装和加工材料中可能是减少表面细菌污染,提高食品安全性的一种有前途的策略。在这篇综述中,我们总结了天然和合成的纳米柱表面的形成及其作用机理,并强调了影响其机械杀菌活性的因素。
