Nanocomposite based on restacked crystallites of β-NiS and Ppy for the determination of theophylline and uric acid on screen-printed electrodes

Abstract

We synthesized calcinated β-NiS with a highly crystalline porous nature and mixed it with Ppy to prepare a nanocomposite, which exhibited high electrocatalytic activity and this was then used to detect theophylline and uric acid with high sensitivity and stability.
