用于先进结构的纳米材料的产生引起了人们对生物矿化领域越来越大的兴趣。许多微生物能够合成基于无机的结构。例如，硅藻使用无定形二氧化硅作为结构材料，细菌合成磁铁矿(Fe3O4)颗粒并形成银纳米颗粒，酵母细胞合成硫化镉纳米颗粒。生物矿化和将纳米结构的无机成分组装成分级结构的过程导致了各种方法的发展，这些方法模仿用于无机材料合成的生物分子中的识别和成核能力。在这份报告中，我们描述了使用从组合噬菌体展示多肽文库中鉴定的银结合多肽来体外生物合成银纳米颗粒。
The creation of nanoscale materials for advanced structures has led to a growing interest in the area of biomineralization. Numerous microorganisms are capable of synthesizing inorganic-based structures,. For example, diatoms use amorphous silica as a structural material, bacteria synthesize magnetite (Fe3O4) particles and form silver nanoparticles, and yeast cells synthesize cadmium sulphide nanoparticles. The process of biomineralization and assembly of nanostructured inorganic components into hierarchical structures has led to the development of a variety of approaches that mimic the recognition and nucleation capabilities found in biomolecules for inorganic material synthesis,,,,. In this report, we describe thein vitrobiosynthesis of silver nanoparticles using silver-binding peptides identified from a combinatorial phage display peptide library.
