Upcoming Laser Technology to Relieve Diabetics of Finger Pricking Misery for Tests

Around the world, millions of people that are affected with diabetes have to prick their fingers to check their blood sugar levels. For certain diabetics, they have to price their fingers multiple times a day, which can result in painful blood blisters. However, a new technology being developed at the University of Leeds could provide a solution to this painful finger pricking for diabetics.
The University of Leeds is currently developing a laser based, non-invasive technology to test blood sugar levels. This technology utilizes a small device that has in build low powered lasers. This device does not only promise the relief from finger pricking, but also a simpler and cheaper alternative to the existing two methods which is using finger pricking and disposable sample strips and the other invasive continuous monitors that are implanted sensors which call for regular replacement.
This laser technology also has the potential to work for continuous monitoring, which can be blessing especially for those with Type I diabetes. This technology is built using a nano silica glass that has ions, which create a fluoresce in infrared light when a low capacity laser light hits them. When this glass is in contact with the patient’s skin, its extent to fluorescence signal tends to vary in relation to the blood glucose concentration.
This device measures the time taken for the fluorescence to last and uses it to measure the blood glucose level in a patient’s bloodstream without the need to prick the finger. This entire process takes less than half a minute. According to the Professor Jose at the University of Leeds, this glass uses their sensors and acts a similar way to that of the glass used in smartphones. And this device is cheap compared to its counterparts. He also said that that this smart wearable device could be just a step from a product that sends alerts to the patients or doctors phones.
