Abstract

Abstract : A colorimetric probe of Pb 2+ has been designed based on the mechanism that a supramolecular probe selectively recognized the Pb 2+ -induced conformational transition of G-quadruplexes. Abstract : A colorimetric probe of Pb 2+ has been designed based on the mechanism that a supramolecular probe selectively recognized the Pb 2+ -induced conformational transition of G-quadruplexes. The probe exhibited high sensitivity and selectivity towards Pb 2+, which enabled it to be practically used in detection of the Pb 2+ level in a freshwater system.
