Investigating the effect of 6-mercaptohexanol on the performance of a biosensor based on nanosurface energy transfer between gold nanoparticles and quantum dots

Anal. Methods, 2021, 13,2092-2098
DOI: 10.1039/D1AY00209K, Paper
Qizhen Lai, Yucheng Liu, Lan Ge, Yeling Yang, Xinghu Ji, Zhike He
The MCH treatment of DNA-AuNPs allowed the free DNA-QDs to be more distant from the surface of DNA-AuNPs, weakening their NSET quenching effect on free DNA-QDs in the presence of a target, which endows MCH/DNA-Au-QDs with a higher signal to background ratio.
