title: Crystal violet as a G-quadruplex-selective probe for sensitive amperometric sensing of lead.
abstract: A sensitive and selective amperometric sensing platform for lead (Pb(2+)) was developed based on a Pb(2+)-induced G-rich DNA conformational switch from a random-coil to G-quadruplex (G4) with crystal violet as the G4-binding indicator.
