金属和金属氧化物纳米颗粒（NP）具有许多用途，并且NP的尺寸、形状和纯度必须均匀以确保颗粒以已知和一致的方式起作用。均匀纳米颗粒的合成通常需要高温、高压和苛刻的化学试剂，这在经济上和环境上都是昂贵的。在自然界中，生物矿化用于生产精确的纯NP，使用温和得多的反应条件和试剂。最近，生物启发的方法已被采用，以生产NP使用的蛋白质和肽：发生在自然界中，人工选择从随机肽库的生物淘选，或合理设计，以控制NP形成温和的条件下。在这里，我们强调了最近的进展，金属和金属氧化物NP结合和合成使用蛋白质和肽。然后，我们调查生物启发图案的纳米粒子到表面上。这样做是为了展示未来开发环境友好的生物模板装置和纳米技术的可能途径。
Metal and metal oxide nanoparticles (NPs) have many uses, and the size, shape and purity of the NPs must be uniform to ensure that the particles function in a known and consistent manner. The synthesis of uniform NPs usually requires high temperatures, high pressures, and harsh chemical reagents, which is both economically and environmentally costly. In nature, biomineralisation is used to produce precise, pure NPs, using far milder reaction conditions and reagents. Recently, a bioinspired approach has been adopted to produce NPs using proteins and peptides that: occur in nature; are artificially selected from a random peptide library by biopanning; or are rationally designed to control NP formation under mild conditions. Here we highlight the recent advances in metal and metal oxide NP binding and synthesis using proteins and peptides. We then investigate bioinspired patterning of NPs onto surfaces. This is done to demonstrate the possible avenues available to develop environmentally friendly, biotemplated devices and nanotechnologies in the future.
