We have recently developed a universal procedure to functionalize inorganic nanoparticles with a dense layer of DNA through the self-assembly of DNA block copolymers and nanoparticles. This functionalization strategy allows one to combine the useful physical properties of inorganic nanoparticle with the enhanced DNA binding properties that originate from the high surface DNA density. In particular, the hybrid nanostructures exhibit orders of magnitude higher binding constants than regular DNA strands. This chapter presents a detailed protocol for the preparation and characterization of DNA block copolymer assemblies loaded with nanoparticles.
我们最近开发了一种通用方法,通过DNA嵌段共聚物与纳米颗粒的自组装,用致密的DNA层对无机纳米颗粒进行功能化。这种功能化策略使人们能够将无机纳米颗粒的有用物理性质与源自高表面DNA密度的增强的DNA结合性质相结合。特别是,这种杂化纳米结构表现出比常规DNA链高几个数量级的结合常数。本章介绍了负载纳米颗粒的DNA嵌段共聚物组装体的制备和表征的详细方案。
