Research Area
In this study, the carboxyl group functionalized-CdSe/ZnS quantum dots (QDs) and melamine-formaldehyde resin particles captured-aminofluorescein (AF) were synthesized. They were conjugated with the sol-gel mixture of glycidoxypropyl trimethoxysilane (GPTMS) and aminopropyl trimethoxysilane (APTMS) for the fabrication of hydrogen peroxide sensing membranes. CdSe/ZnS QDs joined the redox reaction of hydrogen peroxide via the reductive pathway involving the electron transfer to an acceptor that resulted in fluorescence quenching of QDs, whereas aminofluorescein (AF) was used as a reference dye. Herein, the ratiometric fluorescence of QDs and AF was proportional to the concentration of hydrogen peroxide
