[Asia Economy Reporter Ki-min Lee] Samsung Electronics has demonstrated the commercialization potential of non-invasive blood glucose measurement technology, which has been considered a challenging method among diabetes testing techniques. Non-invasive blood glucose measurement technology measures blood glucose levels without drawing blood.

On the 29th, according to Samsung Electronics Newsroom, the research team at Samsung Electronics’ Advanced Institute of Technology published a paper related to a new method of measuring blood glucose without drawing blood in the world-renowned academic journal Science Advances. This technology, developed in collaboration with the Massachusetts Institute of Technology (MIT) research team, is a non-invasive glucose monitoring (NGM) technology that uses laser light to measure blood glucose.

Typically, diabetic patients measure blood glucose through an invasive method that involves pricking the fingertip to draw blood, causing pain and discomfort with each test. For this reason, the academic community has been steadily researching non-invasive measurement methods since the 1990s, but accurately measuring blood glucose concentration without blood sampling has been considered a difficult challenge.

The research team applied Raman spectroscopy for accurate non-invasive measurement. Raman spectroscopy is a measurement method that identifies substances by utilizing the phenomenon where the wavelength of laser light changes due to the unique vibrations of molecules when the light is irradiated and scattered by the material.

The researchers developed a "non-contact off-axis Raman system" that directs obliquely tilted light to reach the subcutaneous layer of the skin to read the Raman spectrum of glucose inside the body, thereby improving accuracy. They explained that this method can raise the correlation coefficient, an accuracy indicator of non-invasive signal measurement, up to 0.95.

Nam Sang-hyun, Master at Samsung Electronics’ Advanced Institute of Technology, said, "This research is significant in that it provides experimental evidence and direction," adding, "We will strive to commercialize non-invasive blood glucose sensors through further research."
