Paper Abstract

Noninvasive and minimally invasive blood glucose sensing is one of most interesting research fields. For the noninvasive measurement using near-infrared spectroscopy, the optical signal was impaired by the uncertain physiological noise and systematical drift. A floating reference method by differentially processing two signals from reference point and measuring point was used to deal with these uncertain noises. For the minimally invasive measurement, interstitial fluid extracted by ultrasound and vacuum is investigated. Low-frequency ultrasound was applied to enhance the skin permeability to interstitial fluid by disrupting the stratum corneum lipid bilayers. In this paper, a kind of protein absorbing the glucose specifically called D-galactose/D-glucose Binding Protein (GGBP) was introduced to construct a novel surface plasmon resonance (SPR) measuring system. By immobilizing GGBP onto the surface of the SPR sensor, a new detecting system for glucose testing in mixed solution was developed. The experimental result indicated that, the SPR system succeeded in distinguishing glucose resolution of 0. 1 mg/L, and had linear relationship between 0.5 mg/L and 5 mg/L.
