Researchers at ATTD 2023 showcased advancements in the field of non-invasive glucose monitoring, highlighting innovative approaches. One of them has to do with analyzing breath to detect glucose levels and other relevant compounds.
BOYDSense is developing a device called Lassie, and it’s so small that it fits in the pocket. Lassie measures volatile organic compounds (VOCs) produced by the body during some processes, such as glucose metabolism. Clinical trials with individuals suffering from type 2 diabetes have successfully identified VOCs correlating with glucose levels and are working on an algorithm for precise measurements.
The other technique is known as Raman spectroscopy, and it uses light to measure glucose by simply touching a button with a finger. RSP Systems is developing a touch glucose monitor (TGM), which has shown promising accuracy when it comes to clinical trials. The challenge ahead involves enhancing the device’s convenience, such as integrating it into a wristwatch and integrating data with other devices. It needs to be said that the fundamental hurdles of creating a functioning sensor and employing spectroscopic technology have been overcome.
Can tears be used as glucose measurement?
One of the amazing facts regarding non-invasive glucose monitoring is that scientists have also been exploring the possibility of using tears as a source of glucose measurement. How can that be possible? Quite simple, actually, once you dive a bit into the explanation. Tears contain a variety of biomarkers, such as glucose, which could be extracted and analyzed to provide information about the blood glucose levels of a person. This approach has the potential to revolutionize glucose monitoring for those who suffer from diabetes, as it would eliminate the need for traditional finger-prick tests, offering a painless method of monitoring blood sugar levels.
Using tears as a source of glucose measurement remains in the research and development stage, and it holds great promise for the future of non-invasive glucose monitoring.
