Properties and synthesis of silver nanoparticles
Table of contents: diameter, surface area, and volume shape and crystallinity nanoparticle surface particle stability surface chemistry and functionalization measuring silver nanoparticle concentration diameter, surface area, and volume nanoparticles have unique properties due to their small size. The controllable synthesis of nanocrystals with different shapes is very important and challenging in the present work, silver nanoparticles with different structural architectures, from nanorods, triangular plates, hexagonal plates, and nanocubes to polyhedrons have been synthesized successfully in high yield by a solvothermal process. Such measurements were possible because of the development of a novel synthetic method for the size‐controlled synthesis of chemically clean, highly crystalline silver nanoparticles of narrow size distribution. Silver nanoparticles properties antibacterial mode of action: bacteria have different membrane structures, which are the bases of their general classification as gram-positive or gram-negative structural differences reside in the organization of the key component of the cell wall, peptidoglycan, which is located immediately outside the .
