Because of the unique optical properties of gold nanomaterials, the preparation of gold nanomaterials with excellent chirality has received extensive attention. In order to develop a simple fabrication method for three-dimensional chiral Au nanostructures with a size of several hundred nanometers, chiral gold nanoparticles were developed to transfer chirality of a peptide to gold nanoparticles. In this study, the controlled synthesis of asymmetric gold nanopolyhedrons was achieved. The asymmetric gold nanopolyhedrons prepared via peptide-directed growth can exhibit strong circular dichroism (∼±50 mdeg) couplets in the visible range (500-600 nm). Also, the morphology of chiral Au nanododecahedrons-peptide particles showed distorted and asymmetric properties. In order to prove that the size and spatial structure of gold nanopolyhedrons have an influence on their chiral optical properties, Au nanotrioctahedron-peptide particles were prepared by using Au nanotrioctahedrons with different morphologies. Au nanotrioctahedron-peptide particles also exhibited circular dichromatic couplets in the visible region.

具有出色的手性光学性质的自组装肽官能化金纳米多面体。
由于金纳米材料的独特光学性质，具有优异手性的金纳米材料的制备受到了广泛的关注。为了开发尺寸为几百纳米的三维手性金纳米结构的简单制备方法，开发了手性金纳米颗粒以将肽的手性转移至金纳米颗粒。在这项研究中，实现了不对称金纳米多面体的受控合成。通过肽定向生长制备的不对称金纳米多面体可以在可见光范围（500-600 nm）内表现出很强的圆二色性（〜±50 mdeg）。而且，手性金纳米十二面体-肽颗粒的形态显示出扭曲和不对称的性质。为了证明金纳米多面体的大小和空间结构对其手性光学性能有影响，采用不同形态的金纳米三面体制备了金纳米八面体-多肽颗粒。金纳米三八面体-肽颗粒在可见光区域也显示出圆形的双色对联。
