Nanotechnology is rapidly advancing in almost every area, such as the pharmaceutical industry, food industry, nano fabrics, electronics, wastewater treatment, and agriculture.
Metallic nanoparticles are commonly used in various fields but are especially important in the pharmaceutical industry. Metallic nanoparticles have a size range of 10 nm to 100 nm.
Two techniques are used to synthesize metallic nanoparticles, the top-down approach and the bottom-up approach. These techniques can be synthesized using three different methods: physical, chemical, and biological. Chemical methods include coprecipitation, reduction, sonochemical, solvothermal, and others, while physical methods include discharge, milling, and ion implantation. Biological methods include plants and their extracts, agricultural wastes, microorganisms, and seaweeds. Scanning electron microscopy, transmission electron microscopy, dynamic light scanning, and other techniques are used to characterize them.
All metallic nanoparticles are biocompatible and have special optical, electrical, magnetic, and chemical properties. They are used in various industries, including the pharmaceutical industry as an anticancer agent, antibacterial, antifungal, antioxidant, antidiabetic, and biosensors. Gold, silver, iron oxide, zinc oxide, platinum, copper oxide, and palladium nanoparticles are the most common metal nanoparticles used in the pharmaceutical industry. Monometallic and multimetallic nanoparticles are broadly classified under this.
This article focuses on the major metallic nanoparticle groups, including synthesis, applications, case studies, toxicity, regulatory aspects and innovative approaches to metallic nanomaterials.
纳米技术在几乎各个领域都在迅速发展,如制药业、食品工业、纳米纤维、电子、废水处理和农业。
金属纳米粒子在各个领域都得到了广泛应用,但在制药行业尤为重要。金属纳米粒子的粒径范围为 10nm 至 100nm。
合成金属纳米粒子有两种方法,自上而下法和自下而上法。这两种方法可以通过三种不同的方法合成:物理、化学和生物。化学方法包括共沉淀、还原、超声化学、溶剂热法等,而物理方法包括放电、研磨和离子注入。生物方法包括植物及其提取物、农业废弃物、微生物和海藻。扫描电子显微镜、透射电子显微镜、动态光散射等技术用于对它们进行表征。
所有金属纳米粒子都是生物相容的,具有特殊的光学、电学、磁学和化学性质。它们被应用于各个行业,包括制药行业作为抗癌剂、抗菌剂、抗真菌剂、抗氧化剂、抗糖尿病和生物传感器。金、银、氧化铁、氧化锌、铂、氧化铜和钯纳米粒子是制药行业最常用的金属纳米粒子。单金属和多金属纳米粒子在此基础上进行了广泛分类。
本文重点介绍了主要的金属纳米粒子群体,包括合成、应用、案例研究、毒性、监管方面和金属纳米材料的创新方法。
