- Russia is developing a noninvasive technology for diagnosing complications of diabetes
Russian scientists are developing a technology that will allow measuring tissue parameters in easily accessible areas of the body, such as a finger, to assess the likelihood of complications in various organs due to diabetes. To carry out the diagnosis, a nasty sensor will be created by analogy with a device for measuring oxygenation. Valery Tuchin, the world's most cited biophotonics scientist, told Izvestia about this in an exclusive interview.
"Right now we are very concerned about the problem of diabetes. We have set ourselves the task to monitor the condition of a sick body using non-invasive optical methods. We study tissue glycation, the process by which proteins and lipids attach glucose molecules. As a result, the protein molecule becomes larger in size, crosslinking appears between the protein molecules and the tissue thickens. This means that the entire metabolism is hampered. This happens with diabetes and aging. Diffusion (penetration of one substance into another. — Ed.) of any molecule is difficult. And we measure the diffusion rate as a marker of the degree of tissue glycation," the specialist said.
According to the scientist, his team is currently looking for a correlation between the rate of diffusion of molecules in surface tissues, which can be easily measured using light, namely in the skin, in the oral mucosa, on the lip or, for example, the sclera of the eye, and in internal organs, the heart muscle, brain. When this work is completed by the indicator, the technique will allow us to say, for example, that with such a diffusion coefficient, the patient has a high chance of first having a heart attack and then losing his eyesight, and something needs to be done now.
