According to an article at the Globes [online], the Israeli company Glucon has presented good clinical results at the American Diabetes Association’s 66th Scientific Sessions. Company’s prototype noninvasive glucometer was shown “by a clinical study to be as precise as invasive blood sugar measurement devices.”
Glucon’s photoacoustics-based technology explained:
Photoacoustics involves ultrasonic waves created by the absorption of light. These ultrasound waves are generated by illuminating the tissue with laser pulses at several selected wavelengths. Analysis of the acoustic signals can map the depth profile of the absorbance of light in the tissue.
Glucon uses Photoacoustics to map the influence of the glucose on the optical properties of the blood inside blood vessels. The acoustics element is used for the localization of the measured volume inside a blood vessel, as well as removing the influence of the outer layers of the skin. The optics element provides the specificity to glucose by using several light wavelengths.
