title: Turn-on and label-free fluorescence detection of lead ions based on target-induced G-quadruplex formation.
abstract: Using a guanine-rich sequence (AGRO100) and N-methyl mesoporphyrin IX (NMM), a turn-on and label-free fluorescent Pb(2+) sensor with high sensitivity and low background fluorescence was presented as a representative of five turn-on sensing systems.
