Abstract

This paper reports on an experimental research of a 2-hydroxypropyl-β-cyclodextrin (HP-β-CD) enveloped 10-methylphenothiazine (MPT) catalyst (MPT-HP-β-CD) with high sensitivity and wonderful electrical conductivity for the electrochemical detection of reduced glutathione (GSH) in a neutral environment. We obtained a linear response range from 10−6 mol L−1 to 5.8 × 10−4 mol L−1 for GSH with a low detection limit of 2.87 × 10−7 mol L−1, providing a potentially usefulness in the development of sensors for non-enzyme detection of GSH.
