Nano Sensors for Detection of Diabetes- A Review

Blood sugar is the primary source of energy generated by the human body through meals. Diabetes mellitus, or diabetes, is a condition in which the body’s insulin is ineffectively used or the pancreas is unable to create enough insulin. If a patient is being treated with insulin, continuous blood sugar monitoring is important because it can help patients make important decisions regarding food, physical activity, and medicines, as well as allow them to proactively manage their blood sugar levels to lower the risk of hypoglycaemia. Multiple methods/techniques are used to monitor blood glucose levels, and various developments have occurred over time. Traditional techniques of monitoring glucose and insulin levels rely on a painful and inconvenient procedure to keep track of these values. Several studies have primarily focused on the development of better sensing technology to address the challenges. The primary goal of this work is to give a high-level review of Nano sensors that are used to monitor blood sugar levels.
