Abstract
In this report, Platinum iron nanoparticles (FePt NPs) were attached onto Mesoporous silicon spheres (MSS) by a facile polyol process. Based on the prepared nanoparticles, a novel colorimetric sensor for fast and sensitive determination of H2O2 was established. The established colorimetric sensing platform exhibited perfect peroxidase-like activities confirmed by oxidating 4, 4’-Bi-2, 6-xylidine (TMB) with H2O2. After optimizing the reaction conditions, the linearity of H2O2 determination ranged from 40 to 300 μM and the limit of detection (LOD) of 18.27 μM.
