Abstract

A simple fluorescein derivative as a fluorescent probe was synthesized for the detection of malondialdehyde (MDA) through a synergistic reaction to achieve ring-opening of fluorescein and formation of a benzohydrazide derivative. It exhibited high sensitivity and selectivity for MDA detection. The probe could also detect MDA quickly (within 60 s) and visually via UV-vis and fluorescent modes. Moreover, this probe showed good performance in the imaging of MDA in living cells and bacteria.
