摘要
基于发展纳米材料"绿色合成技术"重要性,生物合成纳米材料已成为纳米合成技术研究热点。微生物具有廉价、易培养、繁殖快等优点被应用于多种纳米材料的生物合成研究,成为生物合成纳米材料的重要生物类群。本文综述了细菌、放线菌、酵母菌以及真菌等微生物应用于纳米生物合成技术的发展;着重评述了纳米材料微生物合成生物方法、纳米材料微生物合成相关机制、纳米材料形貌和尺寸微生物调控合成方法以及应用研究进展;并对纳米材料微生物合成技术未来发展趋势进行了展望。
Biosynthesis of nanomaterials,as a novel＂green synthesis technology＂,has attracted increasing interests.Many microorganisms such as bacteria,actinomycetes（eukaryotes）,as well as yeasts and fungi（prokaryotes） have been found to have ability to biosynthesize nanomaterials intracellularly or extracellularly.A series of metal and semiconductor nanomaterials with the excellent features of high monodispersity,stabilization,adjustable size,and biological activity,such as Au,Ag,Au-Ag,Fe3O4 / Fe3S,Titanium and CdS,CdSe,and Silica,have been biosynthesized.Here,we provided a brief overview of the current research on the use of microorganisms in the biosynthesis of nanomaterials.The biological procedures,biosynthesis mechanism,controlled biosynthesis on the shape and size,and their applications were summarized.The prospects of biosynthesis using microorganism have also been addressed.
