Advancements in enzyme-free electrochemical glucose sensor materials.

Increased health awareness has called for better health monitoring devices, resulting in continuous research and advancement in glucose sensors. Innovations in both enzymatic and enzyme-free sensors (or non-enzymatic) are revolutionising diabetes control. While enzymatic sensors offer superior sensitivity and selectivity, enzyme-free sensors are preferred for stability and affordability, advancing the quest for rapid and accurate glucose tests. Progress in the development of enzyme-free glucose sensors is being achieved by improvements in electrode materials as well as sensor design. The selection of electrode materials is crucial in these sensors for attaining optimum values of sensing time as well as accuracy. Numerous electrode materials, including graphene, carbon nanotubes, metal oxides (such as platinum and gold), and conductive polymers, have been developed and studied by researchers to be employed in glucose sensors. Among the most critical factors being considered for developing glucose sensor materials is the selectivity for glucose molecules without interference due to the presence of another molecule. This article focuses on tracing recent developments in enzyme-free glucose sensor research, highlighting efforts to overcome limitations and drive innovation in glucose monitoring technology.
