We report a novel strategy to functionalize silver nanoparticles with chimeric phosphorothioate modified DNA (ps-po-DNA) and the fabrication of bimetallic core-satellite nanoclusters that each contain a silver core (diameter 32 nm) surrounded by 5 nm gold NPs.
我们报告了一种新的策略,即用嵌合硫代磷酸酯修饰的 DNA(ps-po-DNA)功能化银纳米粒子,并制备了包含银核(直径 32nm)的双金属核-卫星纳米簇,银核被 5nm 的金纳米粒子包围。
