Representative pathogenic bacteria such as Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) are widespread in nature and pose a threat to human health. To control the propagation of these pathogens from the source, the key is to design broad-spectrum antibacterial materials to reduce the serious damage of pathogenic bacteria. At present, more and more nanoparticles are widely researched and applied due to their multi-pathway antibacterial properties, such as regulating physiology, biochemistry and physical chemistry. In this work, we synthesized a uniformly dispersed and stable spherical nanoparticle (TiO2@V2O5) synthesized by self-assembly of tianium dioxide and vanadium pentoxide. Based on its excellent photosensitive properties, TiO2@V2O5 nanoparticles have showed excellent antibacterial properties under the light irradiation due to the production of hydroxyl radicals in antibacterial and mechanism tests. In addtion, related cell and plant experiments have showed that TiO2@V2O5 nanoparticles are excellent biocompatible materials, it could be widely used in environmental pollution control, limiting the serious damage caused by pathogens.

智能响应型自组装纳米粒子TiO2@V2O5的光敏特性和协同抗菌能力。

具有代表性的致病菌如大肠杆菌E.coli)和金黄色葡萄球菌S.aureus)在自然界中广泛存在,对人类健康构成威胁。要从源头上控制这些病原菌的繁殖,关键是设计广谱抗菌材料,减少病原菌的严重破坏。目前,越来越多的纳米粒子因其具有调节生理、生物化学和物理化学等多途径抗菌特性而被广泛研究和应用。在这项工作中,我们合成了一种均匀分散且稳定的球形纳米颗粒(TiO 2 @V 2 O 5) 通过二氧化钛和五氧化二钒的自组装合成。TiO 2 @V 2 O 5纳米粒子基于其优异的光敏性能,在抗菌和机理试验中,由于产生羟基自由基,在光照射下表现出优异的抗菌性能。此外,相关细胞和植物实验表明,TiO 2 @V 2 O 5纳米颗粒是优良的生物相容性材料,可广泛用于环境污染控制,限制病原体造成的严重破坏。
