Double enzymatic cascade reactions within FeSe-Pt@SiO2 nanospheres: synthesis and application toward colorimetric biosensing of H2O2 and glucose.

Abstract

A facile process was developed for the synthesis of FeSe-Pt@SiO2 nanospheres based on the hydrothermal treatment of FeCl3·6H2O, selenium and NaBH4 in ethanolamine solvent, followed by reducing HPtCl4 with NaBH4 in the presence of FeSe particles to obtain FeSe coated with Pt NPs (FeSe-Pt), ending with a surfactant assembled sol-gel process to obtain FeSe-Pt… (More)
