Non-invasive glucose monitoring

Abstract

Several recent reports claim success in measuring blood glucose non-invasively in human subjects with near-infrared spectroscopy. A critical examination of these published results suggests more fundamental research is needed to verify the validity of these claims. In addition, progress continues in assessing the utility of near-infrared spectroscopy as a non-invasive probe for continuous bioreactor monitoring during fermentation processes. Recent work demonstrates that five critical fermentation components, including glucose, may be measured simultaneously.
