ZnSe nanodisks:Ti3C2 MXenes-modified electrode for nucleic acid liquid biopsy with photoelectrochemical strategy.

Mikrochimica acta - 2 Dec 2021

Meng Yuchan, Qin Nana, Hun Xu

Abstract excerpt

ZnSe nanodisks:Ti3C2 MXene complex was prepared for the first time. Based on its remarkable photoelectrochemical performance, combined with the enzyme-free toehold-mediated strand displacement reaction, a photoelectrochemical biosensor for the detection of the non-small-cell cancer biomarker ctDNA KRAS G12D was developed. ZnSe nanodisks were in situ grown on Ti3C2 MXene surface by two-step hydrothermal method....
