利用植物提取物合成银纳米粒子(AgNPs)比化学、物理和微生物(细菌、真菌、藻类)方法更具优势。在植物合成方面，植物提取物的生物化学多样性、非致病性、低成本和反应参数的灵活性是导致不同形状、大小和用途的AgNPs产量高的原因。同时，必须根据植物提取物的易得性、大规模纳米合成潜力和无毒性质等参数来选择合适的植物工厂来合成AgNPs。本文对AgNPs的合成进行了综述，重点介绍了利用植物提取物进行生物合成。对合成AgNPs的植物提取物的选择以及利用不同植物提取物合成AgNPs的案例研究提出了几点看法。给出了有助于提高纳米颗粒产率的反应参数。本文还对植物提取物合成的银纳米粒子的合成机理、应用现状和前景进行了讨论。本审查概述了与使用AgNPs有关的限制。
Uses of plants extracts are found to be more advantageous over chemical, physical and microbial (bacterial, fungal, algal) methods for silver nanoparticles (AgNPs) synthesis. In phytonanosynthesis, biochemical diversity of plant extract, non-pathogenicity, low cost and flexibility in reaction parameters are accounted for high rate of AgNPs production with different shape, size and applications. At the same time, care has to be taken to select suitable phytofactory for AgNPs synthesis based on certain parameters such as easy availability, large-scale nanosynthesis potential and non-toxic nature of plant extract. This review focuses on synthesis of AgNPs with particular emphasis on biological synthesis using plant extracts. Some points have been given on selection of plant extract for AgNPs synthesis and case studies on AgNPs synthesis using different plant extracts. Reaction parameters contributing to higher yield of nanoparticles are presented here. Synthesis mechanisms and overview of present and future applications of plant-extract-synthesized AgNPs are also discussed here. Limitations associated with use of AgNPs are summarised in the present review.
