Fluorescent glucose biosensor
Fluorescent glucose biosensors are devices that measure the concentration of glucose in diabetic patients by means of sensitive protein that relays the concentration by means of fluorescence, an alternative to amperometric sension of glucose. No device has yet entered the medical market,〔No fluorescent biosensor has yet entered the medical market, however, in the market for research tools several fluorescent biosensors are present, such as a (kit ) using (fischeri )〕 but, due to the prevalence of diabetes, it is the prime drive in the construction of fluorescent biosensors.

Over the years, using a combination of rational design and screening approaches, many possible combinations of fluorescent sensor for glucose have been studied with varying degrees of success: In most approaches, the glucose concentration is translated into a change in fluorescence either by using a pair〔〔〔〔〔Chinnayelka, S. and M.J.
