A highly specific and sensitive electroanalytical strategy for microRNAs based on amplified silver deposition by the synergic TiO2 photocatalysis and guanine photoreduction using charge-neutral probes

Abstract

TiO₂ photocatalysis and guanine photoreduction were synergically combined for amplifying silver deposition for the electroanalysis of short-chain microRNAs with guanine bases using charge-neutral probes. It could allow for the highly specific and sensitive detection of microRNAs in the blood as well as the identification of their mutant levels.
