Impedimetric and amperometric genosensors for the highly sensitive quantification of SARS-CoV-2 nucleic acid using an avidin-functionalized multi-walled carbon nanotubes biocapture platform.
本文报道两种用于定量检测SARS-CoV-2核酸的新型基因传感器,均以玻璃碳电极为基底,修饰由多壁碳纳米管(MWCNTs)非共价结合亲和素(Av)构成的生物捕获纳米平台,用于固定生物素化DNA探针。阻抗型传感器通过[Fe(CN)6]3-/4-电荷转移电阻增加实现无标记、无扩增检测,线性范围为1.0×10−18–1.0×10−11 M...
