Researchers in Shanghai have developed a non-invasive method for monitoring blood glucose levels that does not require puncturing the skin. The new method allows individuals to measure their blood sugar levels by simply placing the palm of their hand on a special device, according to China Daily, a partner of TV BRICS.
The discovery, the publication notes, could greatly simplify the lives of people with diabetes, as regular blood sugar control using traditional methods often causes discomfort.
The scientists used optical coherence tomography – an imaging technique that uses optical radiation – to accurately measure skin thickness. Using Raman spectroscopy, a method of analysing the structure of matter using light, they then developed a method that allows blood glucose levels to be monitored through the skin without the need to draw blood.
The method has already undergone clinical trials involving 200 diabetic patients and 30 healthy people. According to reports, 99.4 per cent of the measurements met acceptable medical standards.
An additional advantage of the technology is its versatility. It does not require individual customisation and is suitable for people of different ages and builds, making it promising for mass adoption.
