Current glucose monitoring procedures for the rising numbers of diabetics worldwide are intrusive, uncomfortable, time-consuming and a provides a continual financial strain on families. Since, the noninvasive glucose monitoring technology gets over these drawbacks, recently a lot of research is being done in this particular area, and it represents a lucrative and interesting market for many businesses. Electrochemical sensors have drawn a lot of interest recently for the detection of certain bio-molecules due to their high sensitivity, selectivity, simplicity of fabrication, and speed of response. We provide an overview of nano-material based wearable, non-invasive (NI) glucose monitoring sensors. This review focuses on electrochemical capabilities and constraints of these nano-material based sensors. It also discusses the most recent developments in the use of nano-materials for the electrochemical detection of glucose, its challenges and future trends
