A carbon nanotube/quantum dot based photoelectrochemical biosensing platform for the direct detection of microRNAs

Abstract

A versatile photoelectrochemical biosensing platform was developed based on DNA–CdS quantum dots (QDs) sensitized single-walled carbon nanotubes (SWCNTs)-COOH. Combining with cyclic enzymatic amplification, a convenient, sensitive and specific biosensor for the direct detection of microRNAs (miRNAs) was designed, which provided a novel approach for analysis of miRNAs.
