近几十年来，利用各种物理、化学和生物原理合成无机纳米材料和纳米结构得到了发展。由于纳米材料令人兴奋的特性及其创新的应用，纳米材料和结构的创造一直是一个活跃的研究领域。尽管物理和化学方法已被用于生产纳米材料，但近年来，生物资源作为替代旧生产方法的绿色候选材料，已成为生产各种无机纳米颗粒或其他纳米级结构的重点。在过去的二十年中，利用不同的生物实体生产具有成本效益、生态友好、节能和无毒的纳米材料受到了越来越多的关注，而物理和化学方法使用有毒溶剂，产生有害的副产物，以及高能耗，限制了这些方法在纳米科学和工程中的普及。本文综述了利用细菌、放线菌、真菌、酵母、植物提取物以及蛋白质、多肽、DNA、RNA等信息性生物大分子合成金、银、金银合金、磁性、半导体纳米晶体、二氧化硅、氧化锆、二氧化钛、钯、铋、硒、硫化锑和铂纳米粒子的研究进展，并对生物无机纳米材料的生产现状进行了综述。另一方面，两种众所周知的湿化学技术，即化学还原法和溶胶-凝胶法，已被用于生产各种类型的纳米晶粉末、金属氧化物和有机-无机杂化纳米材料。(c) 2012 Elsevier B.V.版权所有
The synthesis of inorganic nanomaterials and nanostructures by the means of diverse physical, chemical, and biological principles has been developed in recent decades. The nanoscale materials and structures creation continue to be an active area of researches due to the exciting properties of the resulting nanomaterials and their innovative applications. Despite physical and chemical approaches which have been used for a long time to produce nanomaterials, biological resources as green candidates that can replace old production methods have been focused in recent years to generate various inorganic nanoparticles (NPs) or other nanoscale structures. Cost-effective, eco-friendly, energy efficient, and nontoxic produced nanomaterials using diverse biological entities have been received increasing attention in the last two decades in contrast to physical and chemical methods owe using toxic solvents, generate unwanted by-products, and high energy consumption which restrict the popularity of these ways employed in nanometric science and engineering. In this review, the biosynthesis of gold, silver, gold-silver alloy, magnetic, semiconductor nanocrystals, silica, zirconia, titania, palladium, bismuth, selenium, antimony sulfide, and platinum NPs, using bacteria, actinomycetes, fungi, yeasts, plant extracts and also informational bio-macromolecules including proteins, polypeptides, DNA, and RNA have been reported extensively to mention the current status of the biological inorganic nanomaterial production. In other hand, two well-known wet chemical techniques, namely chemical reduction and sol-gel methods, used to produce various types of nanocrystalline powders, metal oxides, and hybrid organic-inorganic nanomaterials have presented.
