Traditional methods of preparing regular-shaped silver chloride nanoparticles for antiseptic use are complex. Squarelike AgCl nanoparticles with an average size of about 400 nm were prepared using the two-dimensional (2D) metal–organic framework nanosheet Ni(pyz)₂Cl₂ (pyz, pyrazine) and the surfactant polyvinyl pyrrolidone (PVP), which exhibit enhanced antibiofilm properties compared with common AgCl nanoparticles. This excellent performance can be attributed to the stronger light absorption ability, which helps in producing a larger amount of hydroxyl radicals that have a strong oxidative function to destroy the structure of bacteria, as well as a larger surface area, which aids in the release of more silver ions into the bacterial cell. This work has provided a creative method for preparing squarelike AgCl nanoparticles with uniform morphology that does not easily agglomerate, showing an immense application prospect in the antibacterial field.

使用 NiCl ₂ (Pyz) ₂基金属-有机框架纳米片模板生长的 Squarelike AgCl 纳米颗粒，用于抗菌应用

制备用于防腐用途的规则形状的氯化银纳米颗粒的传统方法是复杂的。使用二维 (2D) 金属-有机骨架纳米片 Ni(pyz) ₂ Cl ₂制备了平均尺寸约为 400 nm 的方形 AgCl 纳米粒子(pyz, pyrazine) 和表面活性剂聚乙烯吡咯烷酮 (PVP)，与常见的 AgCl 纳米粒子相比，它们表现出增强的抗生物膜特性。这种优异的性能归功于更强的光吸收能力，有助于产生大量具有强氧化功能的羟基自由基来破坏细菌结构，以及更大的表面积，有助于释放更多的银离子进入细菌细胞。该工作为制备形貌均匀、不易团聚的方形AgCl纳米粒子提供了一种创造性的方法，在抗菌领域具有广阔的应用前景。
