Till today we diagnose and treat Diabetes by estimating Glucose level either fasting, postprandial or random by blood examination in the laboratory or by biosensors but now by constantly tracking a person’s glucose levels through their tears or sweat could be one step closer to providing people with diabetes an improved monitoring tool. Researchers report in the journal ACS Nano the development of an ultra-thin, flexible sensor that could be incorporated into contact lenses or on the backs of watches for real-time glucose tracking. The pain of pricking fingers or drawing blood, however, can deter people from vigilantly monitoring conditions such as diabetes that require regular checks.
To take the sting out of the process, wearable glucose sensors are in development but have been hampered by several factors. Some devices can’t detect the low levels of glucose that are in sweat and…
