A silver nanoparticle-poly(methyl methacrylate) based colorimetric sensor for the detection of hydrogen peroxide

Abstract

A colorimetric sensor based on nanoparticles was developed for the detection of hydrogen peroxide. Nanoparticles were made using small sheets of poly(methyl methacrylate) (PMMA) and silver nitrate. The optical properties of the solution were characterized by spectrophotometer using the localized surface plasmon resonance (LSPR) phenomenon. The shape and size of the nanoparticles were obtained using a transmission electron microscope (TEM). Silver-poly(methyl methacrylate) nanoparticles solution (AgNP-PMMA) proved to be particularly sensitive to hydrogen peroxide compared to other analytes. This sensor provided a quick, practical and easy tool to detect hydrogen peroxide.

“…The KG/PEG-Ag NPs also had a lower limit of detection (0.071 μM) and the response time was ~5 s. The transformation of the yellow KG/PEG-Ag NPs to a transparent color in the presence of H2O2 analyte enabled it to be perceived with the naked eye in the detection of H2O2. This possible mechanism was due to the oxidation of Ag 0 to Ag + ions with the electrocatalytic ability of KG/PEG-Ag NPs [21]. These results of the novel colorimetric biosensor were appreciable from the comparison with results of previous studies in the literature (Table 3).…”

“…The localized surface plasmon resonance energy is related to the morphology, composition, size, shape, and dielectric environment of NPs [20]. In this context, Carbone et al prepared a novel colorimetric sensor based on silver-poly (methyl methacrylate) NPs for the detection of H2O2 [21]. Teodoro et al prepared a colorimetric sensor based on cellulose nanowhiskers and Ag NPs with a low limit of detection of 0.014 μM for the detection of H2O2 [22].…”
