چکیده

Abstract After decades of research on non-invasive glucose monitoring, invasive devices based finger blood sampling are still the predominant reference for diabetic patients accurately measuring levels. Meanwhile, continues improving point-of-care technology toward development painless and more accurate devices. Raman spectroscopy is well-known as a potentially valuable approach However, previous studies deal with concentrations that order magnitudes away respect to human tissues’ physiological concentrations, or they propose enhancement methodologies either much complex assure sufficient sensitivity in range. Instead, this study proposes an alternative non-enhanced sensitive from 1 5 mmol/l, which correspond lowest physiopathological level blood. Our findings suggest very selective detection other typical metabolites, usually interfering spectroscopy’s detection. We validate proposed univariate sensing methodology solutions mixed lactate urea, two most common molecules found serum similar features spectra. clearly illustrate reliable by feasible exploiting shifted peak at 1125 ± 10 cm –1 within ranges.

Noninvasive glucose sensing by transcutaneous Raman spectroscopy.

We present the development of a transcutaneous Raman spectroscopy system and analysis algorithm for noninvasive glucose sensing. The instrument and algorithm were tested in a preclinical study in which a dog model was used. To achieve a robust glucose test system, the blood levels were clamped for periods of up to 45 min. Glucose clamping and rise/fall patterns have been achieved by injecting g...

Detection of Glucose Levels Using Excitation and Difference Raman Spectroscopy at the IUSL

Raman spectroscopy such as spontaneous Raman spectroscopy, coherent anti-stokes Raman spectroscopy, and stimulated Raman gain spectroscopy are widely used in physics, chemistry and biology fields for investigations of vibrational modes. To our best knowledge, very few applications of Raman spectroscopy for the in-vitro and invivo patient medical diagnostics have been reported because of low sig...
