For most type 1 diabetes patients it is always much irritating , painful and makes it much discomfort in pricking their fingers to draw blood often a day to monitoring the glucose content in their body. However it is often much necessary to monitor them because excess level of glucose can lead to various causes in body and also leads in lowering the necessary fuel. However MIT’s Spectroscopy Laboratory have come up with a new technique of device to monitor the blood glucose levels using lights. The method determines the chemical compounds in the body based on the frequency of vibrations of the bonds holding the molecule together. Theses infrared rays just scans through the patient fingers and determine the level of glucose without the need of piercing the finger to draw blood.

The research has been undergoing for never 15 years and the drawback they faced with the previous method is that the infrared rays was able to penetrate only about half a millimeter below the skin, so it was only able to measure only glucose level in the entry level of the skin. To over this drawback the researchers came up with a new algorithm that relates the two concentrations, allowing them to predict blood glucose levels from the glucose concentration in interstitial fluid.
