摘要

在金属纳米颗粒生产中使用植物提取物是一种直接、实用、具有成本效益和生态友好的替代有害化学物质的方法。因此,最近发表了几种快速制造银纳米粒子的方法,这些方法对环境是可接受的,并且使用植物材料(包括叶子、树皮和根)的水提取物。本文重点介绍了利用多种植物提取物制备银纳米颗粒(AgNPs)的最新进展,以及这些材料作为抗菌剂的潜在用途。深入分析植物提取物中植物化学物质浓度、提取温度、提取溶剂、反应温度、反应时间、反应ph值和前体浓度的潜在影响。此外,还提供了AgNPs具有强抗菌作用并通过与病原体细胞壁相互作用诱导细胞死亡的潜在机制的广泛细节。此外,虽然形状控制合成的化学方法已经广泛建立,但控制生物生成的AgNPs的形状对其活性有几个有利的影响。

A Recent Advancement Towards Herbal Biomass-Assisted Synthesis of Silver Nanoparticles
Using plant extracts in metal nanoparticle production is a straightforward, practical, cost-effective, and ecologically benign alternative to the use of harmful chemicals. As a consequence, several approaches for the quick manufacture of silver nanoparticles that are acceptable to the environment and use aqueous extracts of plant materials including leaves, bark, and roots have been published recently. In this paper, recent advancements in the area of environmentally friendly manufacturing of silver nanoparticles (AgNPs) using diverse plant extracts are highlighted and expanded upon, along with the potential use of these materials as antibacterial agents. A thorough analysis of the potential effects of phytochemical concentrations in plant extracts, extraction temperatures, extraction solvents, reaction temperatures, reaction times, reaction pHs, and precursor concentrations. Furthermore provided are extensive details on the potential mechanism by which AgNPs have strong antibacterial action and induce cell death in pathogens by interacting with their cell walls. In addition, whereas chemical methods for shape-controlled synthesis are widely established, controlling the shape of biologically generated AgNPs has several advantageous effects on its activities.
