“…Furthermore, this sensor was shown to be selective and applicable in real urine sample analysis. 40 Yuan et al developed a GSH sensor using a 2-dimensional Co-based metal-organic coordination polymer (Co-MOCP) by a simple solvothermal synthesis. The prepared material was characterized with XRD, Fourier transform infra-red (FTIR) spectroscopy and CV.…”

Glutathione (GSH-reduced form) is a tripeptide that plays a vital role as an antioxidant to remove xenobiotics in the human body and changes in GSH levels are a marker for the progression of various diseases. In this context, a highly sensitive non-enzymatic electrochemical biosensor for the detection of GSH has been developed using reduced graphene oxide Manganese oxide (rGMnO) nanocomposite as the nano-interface. Initially, graphene oxide was synthesized by Hummer's method and then thermally reduced in the presence of MnO 2 in a blast furnace to obtain rGMnO nanocompo-site. The nanocomposite was characterized to validate its structure and morphological properties via Scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman, and X-ray photoelectron spectroscopy (XPS). Cyclic voltammetry and amperometry studies showed that upon the addition of GSH, the Pt/rGMnO modified working electrode exhibited a linear response in the range of 1-100 μM at an input voltage of À 0.62 V. The developed sensor was found to have a sensitivity of 0.3256 μA μM À 1 and LOD of 970 nM with a recovery of 92-104 % in real blood serum samples.

The present review focuses on the interplay between electrochemistry and life, events on the border of electrochemistry‐biology‐life science, electrochemistry as the basis, and the information source on oxidative stress (OS) or Red/Ox state of biological systems and food to be investigated. Electroanalytical chemistry provides rapid, relatively simple, and sensitive approaches to assess the redox characteristics and antioxidant activity of biologically active compounds in various samples.OS is a relatively new physiological response concept, recognized in medicine and biology in the last three decades. This phenomenon is caused by an imbalance between (pro)oxidants and antioxidants in living organisms and it is related to the fundamental redox reactions that underlie health signaling and life processes in general. OS can contribute to many pathological conditions and diseases. In particular, it is recognized that a highly contagious infectious disease, coronavirus disease 2019, is associated with an inflammation process related to OS‐induced cellular changes. Recent years have shown a marked increase in electrochemical studies of OS and quantitation of its reductant‐oxidant markers (signaling agents), such as reactive oxygen species and antioxidants.The goal of this overview is to cover the brief scope of modern electrochemical analysis and sensor devices for monitoring biomarkers of OS and antioxidant status of biological systems. By discussing the great potential of potentiometric and voltammetric methods for human health assessment, it is hoped to bridge between recent electrochemical research and medical diagnostic treatment in the 21st century.
