GLUCOSE DETERMINATION BY A PULSED PHOTOACOUSTIC TECHNIQUE - AN EXPERIMENTAL-STUDY USING A GELATIN-BASED TISSUE PHANTOM

A preliminary study of using a gelatin-based in vivo tissue model to i nvestigate some of the near infrared photoacoustic characteristics tha t may influence the sensitivity of noninvasive photoacoustic detection of blood glucose in human tissue is described. It is shown that the o ptical absorption change due to glucose in the near infrared region is small and that the pulsed photoacoustic technique may offer a better detection sensitivity than other conventional optical transmission mea surement systems being developed for blood glucose monitoring
