Based on the complexation of phenylboronic acid (PBA) with Alizarin Red S (ARS), we developed a new chemosensor for the detection of hydrogen peroxide (H2O2) in aqueous media. This platform has demonstrated its ability to detect H2O2via colorimetric, fluorometric, and electrochemical measurements. The experimental observations reveal that the system displays a red-shifted visible colour change, on-off fluorescence response indicating release of indicator (ARS) and turn-on electrochemical signal indicating generation of phenol, after reaction with H2O2. With this work we have demonstrated that our reaction-based indicator displacement assay (RIA) systems, can be employed as an assay for H2O2 and hydrogen peroxide-related species for environmental and physiological detection.
