荧光胶体半导体量子点和等离子体金属纳米颗粒之间的激子-等离子体相互作用可以导致量子点的发射猝灭或增强，其在可再生能源、纳米光子学和生物传感中具有潜在的应用。半导体量子点和金属纳米粒子的混合物具有可控的几何形状，距离和化学计量是潜在的应用至关重要的。而DNA纳米技术，基于两个单链DNA之间的沃森-克里克碱基配对相互作用，为生成完全可编程的功能性金属纳米颗粒和半导体量子点混合纳米材料提供了独特的机会，并提供了对组件的间距，方向和手性的精确控制。本文综述了近年来DNA引导的胶体半导体量子点和金属纳米颗粒自组装异质纳米材料的研究进展。我们还讨论了DNA引导的半导体量子点和金属纳米粒子杂化纳米材料的自组装的挑战和趋势。
The exciton-plasmon interaction between fluorescent colloidal semiconductor quantum dots and plasmonic metal nanoparticles may lead to emission quenching or enhancement of quantum dots, which have potential applications in renewable energy, nanophotonics, and biosensing. Semiconductor quantum dots and metal nanoparticles hybrids with controlled geometry, distance, and stoichiometry are crucial for the potential applications. While DNA nanotechnology, based on Watson-Crick base-pairing interactions between two single-stranded DNAs, has provided unique opportunities to generate fully programmable, functional metal nanoparticles and semiconductor quantum dots hybrid nanomaterials, and offers precisely control over the spacing, orientation, and chirality of the components. This review provides the highlights of the recent progresses in DNA directed self-assembly of colloidal semiconductor quantum dots and metallic nanoparticles heterogeneous nanomaterials. We also discuss the challenges and the trends in DNA directed self-assembly of semiconductor quantum dots and metallic nanoparticles hybrid nanomaterials.
