Rapid and precise detection of hydrogen peroxide (H2 O2 ) holds great significance since it is linked to numerous physiological and inorganic catalytic processes. We herein developed a label-free and washing-free strategy to detect H2 O2 by employing a hand-held personal glucose meter (PGM) as a signal readout device. By focusing on the fact that the reduced redox mediator ([Fe(CN)6 ]4- ) itself is responsible for the final PGM signal, we developed a new PGM-based strategy to detect H2 O2 by utilizing the target H2 O2 -mediated oxidation of [Fe(CN)6 ]4- to [Fe(CN)6 ]3- in the presence of horseradish peroxidase (HRP) and monitoring the reduced PGM signal in response to the target amount...
