7 μA cm-2 mM-1, a low detection limit of 50 nM (a signal-to-noise ratio of 31), as well as good reproducibility and anti-interference ability, which could be used for the real-time in situ electrochemical detection of H2O2 in live cancer cells and cancer tissue. The remarkable performances of the proposed nanohybrid microelectrode will have a…[Read more]
