Nanoenzyme-Based Electrodes in Biomolecular Screening and Analysis

Nanobioelectrochemistry is a multidiscipline branch of science encompassing nanomaterials, biotechnology, and electrochemistry. In principle, nanomaterials with enzyme-like properties, simply referred to as nanozymes, are used in place of natural and traditional artificial enzymes due to their resilience under a wide range of stringent conditions. Additional advantages of nanozymes include extended storage times, cost-effectiveness, and enhanced catalytic properties. Mechanisms of action make use of redox activities to generate a signal that can be used to provide insight on various analytic procedures. Some areas of major application include but are not limited to disease detection and control, in addition to food safety. Herein, we focus on current trends in the use of nanozymes in bioelectrochemistry. Precisely, we highlight how electrodes in nano-bioelectrochemistry may be fabricated for optimum performance. Furthermore, we focus on biosensing techniques, food monitoring, cancer diagnosis, cancer therapy, bacteria detection, and Covid-19 detection as part of current trends in nanozymes in nano-electrochemistry.
