Development of Au–Pd@UiO-66-on-ZIF-L/CC as a self-supported electrochemical sensor for in situ monitoring of cellular hydrogen peroxide

In this study, a novel strategy called MOF-on-MOF was utilized to develop a non-enzymatic electrochemical sensor Au–Pd@UiO-66-on-ZIF-L/CC for real-time in situ detection of H 2 O 2 released from living cells.
