Sensitive and Selective Theophylline Electrochemical Detection on ZnO Nanoflowers/Graphene Oxide/Boron-Doped Diamond Nanoparticles.

ABSTRACT: Theophylline is among bronchodilator drugs consumed to overcome breathing difficulties, but accurate monitoring is required to avoid side effects. Therefore, this study aimed to develop a screen-printed electrode (SPE). Theophylline is among bronchodilator drugs consumed to overcome breathing difficulties, but accurate monitoring is required to avoid side effects. Therefore, this study aims to develop a screen-printed electrode (SPE) modified with zinc oxide nanoflowers (ZnONF) and graphene oxide (GO) nanocomposites along with boron-doped diamond nanoparticles (ZnONF/GO/BDDNPs/SPE) to detect theophylline. ZnONF is synthesized using the hydrothermal method, and the nanoflower morphology is confirmed through field emission-scanning electron microscopy with an average petal size of 62.33 nm.
