Biotemplated mineralization is a promising and ecofriendly approach to manufacture metal nanoparticles and composites with precise size control. Plant viruses are suitable templates for biomineralization because they are chemically robust and highly scalable through molecular farming. Here, we report a gold-nanoparticle-coated tobacco mosaic virus (TMV) synthesized in a test tube or in plant extracts making use of a TMV displaying a gold-binding peptide (GBP). The methods developed are a step toward engineered living materials, where gold nanowires could be formed in plant tissues for sensing or energy harvest applications.
生物模板矿化是一种很有前景且环保的方法，可用于制造尺寸精确可控的金属纳米颗粒和复合材料。植物病毒是生物矿化的合适模板，因为它们化学性质稳定，并且通过分子农业可实现高度规模化生产。在此，我们报道了一种在试管或植物提取物中合成的金纳米颗粒包覆烟草花叶病毒（TMV），该病毒展示了一种金结合肽（GBP）。所开发的方法朝着工程化生物材料迈出了一步，在这种材料中，金纳米线可在植物组织中形成，用于传感或能量收集应用。
