Electrochemical DNA Biosensor Based on Immobilization of a Non-Modified ssDNA Using Phosphoramidate-Bonding Strategy and Pencil Graphite Electrode Modified with AuNPs/CB and Self-Assembled Cysteamine Monolayer.

Sensors (Basel, Switzerland) 2022 Moustakim H, Mohammadi H, Amine A

本文报道了一种替代传统共价固定方法的电化学 DNA 生物传感器构建策略,避免对单链 DNA(ssDNA)捕获探针进行昂贵且复杂的化学修饰。以低成本铅笔石墨电极(PGE)为平台,用碳黑(CB)和金纳米颗粒(AuNPs)修饰,并在其表面自组装半胱胺(CysAm)单分子层;未修饰 ssDNA 通过其 5′端磷酸基团与 CysAm 伯胺形成...
