Label-free colorimetric nanosensor with improved sensitivity for Pb

Abdul Ghaffar Memon, Xiaohong Zhou, Yunpeng Xing, Ruoyu Wang, Lanhua Liu, Mohsin Khan, Miao He

Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 1, doi: 10.1007/s11783-019-1094-7

Abstract:

• Unmodified-AuNP based, colorimetric nanosensor was constructed for Pb2+ detection.

• 5-nucleotide truncation in DNAzyme made complete substrate detachment upon Pb2+.

• Ultrasensitive and selective detection of Lead (II) was achieved with 0.2×10-9 mol/L LOD.
