Abstract
We report a new strategy to prepare DNA mono-modified gold nanoparticles (AuNPs). By adding a short rigid duplex proximal to the AuNPs, the assembly efficiency of DNA mono-modified AuNPs with Y-shaped DNA could be improved nearly 6-fold.
摘要
我们报告了一种新的策略来制备 DNA 单修饰金纳米粒子（AuNPs）。通过在 AuNPs 附近添加一个短的刚性双链体，可以将 Y 型 DNA 修饰的 AuNPs 的组装效率提高近 6 倍。
