A two-photon fluorescent probe for sensitive detection and imaging of γ-glutamyl transpeptidase†
Abstract
A GGT-activated two-photon fluorescent probe (4F-2CN–GSH) was developed based on a cascade reaction. 4F-2CN–GSH could selectivily detect GGT with low detection limit and distinguish ovarian cancer cells from normal cells using both one-photon and two-photon fluorescence imaging.
