Constrained regularization for noninvasive glucose sensing using Raman spectroscopy

Multivariate calibration is an important tool for spectroscopic measurement of analyte concentrations. We present a detailed study of a hybrid multivariate calibration technique, constrained regularization (CR), and demonstrate its utility in noninvasive glucose sensing using Raman spectroscopy. Similar to partial least squares (PLS) and principal component regression (PCR), CR builds an implic...

A BODIPY boronium cation for the sensing of fluoride ions.

In the presence of iodide ions, the cationic p-dimethylaminopyridine adduct of 1,3,5,7,8-pentamethylpyrromethene-boron fluoride [-DMAP](+) reacts with fluoride ions to afford the corresponding brightly fluorescent difluoride -F.

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...
