As a new method to synthesize nanomaterials,biological template method has its unique advantages. This paper gives a brief overview of biological template method,and we focus on the application of three kinds of macro-molecules to prepare the noble metal nanowires,including DNA,microorganism and protein molecules. In the end we summarize the existing problems in the research at present.%生物模板法作为近些年来新发展起来的一种控制合成纳米材料的新方法,有着其独特的优势.本文对生物模板法做了简单的概述,重点列举了DNA分子、微生物、蛋白质分子三大类生物大分子在制备贵金属纳米线中的应用,并概括了目前研究中存在的问题.
