Abstract

Green synthesis is a unique and eco-friendly method of producing nanoparticles that employs plant extracts as reducing and stabilizing agents. This approach offers numerous advantages, including low cost, biocompatibility, sustainability, and ease of operation. ZnO has been applied in various fields such as optical, electrical, magnetic, catalytic, and biological. Drawbacks such as high band gap of 3.37 eV, faster recombination of generated electron hole pair, lower antibacterial activity hinders ZnO nanoparticles utilization. Metal doping is a technique that modifies the nanoparticle’s characteristics by adding impurities into their lattice which improves optical, electrical, magnetic, catalytic, and biological properties of the host material. Silver doped zinc oxide (Ag/ZnO) is one of the promising materials for metal doped nanoparticles due to its enhanced antibacterial, anticancer, sensing, and photocatalytic capabilities. In this paper, we reviewed plant mediated green synthesis of Ag/ZnO nanoparticles and their multifunctional properties for biomedical and environmental application as well as proposed mechanisms of their action.

植物提取物介导的掺银氧化锌的合成：用于环境恢复、微生物抑制、细胞毒性、抗氧化潜力和传感的环保纳米材料

摘要

绿色合成是一种独特且环保的纳米颗粒生产方法，采用植物提取物作为还原剂和稳定剂。这种方法具有许多优点，包括低成本、生物相容性、可持续性和易于操作。ZnO已广泛应用于光、电、磁、催化、生物等领域。3.37 eV的高带隙、产生的电子空穴对的更快复合、较低的抗菌活性等缺点阻碍了ZnO纳米粒子的利用。金属掺杂是一种通过在晶格中添加杂质来改变纳米颗粒特性的技术，从而改善主体材料的光学、电学、磁学、催化和生物特性。银掺杂氧化锌（Ag/ZnO）由于其增强的抗菌、抗癌、传感和光催化能力而成为金属掺杂纳米粒子的有前途的材料之一。在本文中，我们回顾了植物介导的Ag/ZnO纳米颗粒的绿色合成及其在生物医学和环境应用中的多功能特性，以及其作用机制。
