Abstract
We demonstrate a facile approach for converting AgCl to functional silver nanoparticles (AgNPs) via photoreduction in the presence of DNA. The resulting AgNPs are biofunctionalized, and exhibit photostable luminescence and DNA-specific Raman signatures, showing high potential for use in DNA-directed recognition and advanced bioimaging.
摘要
我们展示了一种通过在 DNA 存在下光还原将 AgCl 转化为功能性银纳米粒子 (AgNPs) 的简便方法。所得的 AgNPs 具有生物功能化特性，表现出光稳定的发光和 DNA 特异性拉曼特征，显示出在 DNA 导向识别和高级生物成像中应用的巨大潜力。
