Abstract:

A simple and selective colorimetric method for H 2 O 2 detection in soaked food samples was developed using Au@Ag nanorods (Au@Ag NRs) as the signal conducter. In the presence of H 2 O 2 , silver atoms on the surface of Au@Ag NRs are oxidized to silver ions, thereby resulting in the red-shift of the longitudinal surface plasmon resonance peak of Au@Ag NRs accompanied by a sharp-contrast multicolor change. The linear range for the detection of H 2 O 2 was from 0 to 100 μmol L -1 with a limit of detection of 3.2 μmol L -1 . Compared with the commercialized test strip, the proposed colorimetric sensor showed a much higher color resolution by the naked eyes. © 2018 The Royal Society of Chemistry.
