Good News for diabetics: new gadget ends the painful poke

Indian-origin scientist  has developed pain-free alternative to monitor blood glucose levels.

  • A new technology was discovered by an Indian-origin scientist which uses a laser device. This innovation may help diabetics non-invasively monitor blood glucose levels, eliminating the need for daily finger pricking.
  • Right now, many people with diabetes need to measure their blood glucose levels by pricking their fingers, squeezing drops of blood onto test strips, and processing the results with portable glucometers available.
  • The new technology, is developed by Gin Jose and his team at the University of Leeds. It uses a small device with low-powered lasers to measure blood glucose levels without penetrating the skin. It could give people a simpler, pain-free alternative to finger pricking.

Constant monitoring :-

The technology has continuous monitoring capabilities making it ideal for development as a wearable device. This could help improve the lives of millions of people by enabling them to constantly monitor their glucose levels without the need for an implant.

According to scientist Jose “As well as being a replacement for finger-prick testing, this technology opens up the potential for people with diabetes to receive continuous readings, meaning they are instantly alerted when intervention is needed. This will allow people to self-regulate and minimise emergency hospital treatment.”

How it works :-

At the heart of the new technology is a piece of nano-engineered silica glass with ions that fluoresce in infrared light when a low power laser light hits them.

When the glass is in contact with the users’ skin, the extent of fluorescence signal varies in relation to the concentration of glucose in their blood. The device measures the length of time the fluorescence lasts for and uses that to calculate the glucose level in a person’s bloodstream without the need for a needle. This process takes less than 30 seconds.

“The glass used in sensors is hardwearing, acting in a similar way as that used in smartphones. Because of this, device is more affordable, with lower running costs than the existing self-monitoring systems.”
