Abstract This study reports the synthesis and characterization of vanadium pentoxide nanoplates (VnNp) with the unique shape. Electron microscopy identified morphological alterations on the bacterial surface of representative Gram-positive, Staphylococcus aureus and Gram-negative, Escherichia coli upon VnNp treatment. In addition, Raman spectral mapping also elucidated changes in the bio-molecular signals from these bacteria. Further, the study proved reactive oxygen species (ROS) generation in E. coli biofilms. Overall, the results envision the possible use of VnNp as a potential surface coating agent to impart antibacterial activity.

五氧化二钒纳米片：合成、表征和揭示内在抗菌活性

摘要 本研究报告了具有独特形状的五氧化二钒纳米片 (VnNp) 的合成和表征。电子显微镜在 VnNp 处理后鉴定了代表性革兰氏阳性、金黄色葡萄球菌和革兰氏阴性大肠杆菌的细菌表面的形态学改变。此外，拉曼光谱图还阐明了来自这些细菌的生物分子信号的变化。此外，该研究证明了大肠杆菌生物膜中的活性氧 (ROS) 生成。总体而言，结果设想可能使用 VnNp 作为潜在的表面涂层剂来赋予抗菌活性。
