Synthesis of nanoparticles using microorganisms: a review of its mechanism

摘要:

纳米粒子的合成方法多种多样，包括物理法、化学法和生物合成法，其中生物合成法是以生物为基体的绿色合成方法。由于微生物易于培养、生长快、廉价易得，已成为纳米粒子生物合成法的重要生物类群。微生物和纳米材料的多样性决定了其合成机制的多样化。本文结合国内外的科研报道，着重介绍了目前纳米粒子生物合成机制，并对纳米粒子微生物合成技术未来发展趋势进行了展望。

Abstract:

A variety of physical, chemical and biological methods have been used to synthesize nanoparticles in which biological methods are green chemistry approachs, interconnecting organism with nanotechnology. Microorganisms are an important group of organism which can be used in nanoparticles synthesis, because they are growing fast, easy to culture, inexpensive and widely available. The diversity of microorganisms and nanomaterials determines the diversification of its synthetic mechanism. According to researches of home and abroad, this paper focus on summarizing mechanism of synthesis nanoparticles using microorganisms. The prospects of biosynthesis nanoparticles using microorganism have also been addressed.
