Capacitive Saccharide Sensor Based on Immobilized Phenylboronic Acid with Diol Specificity
A capacitive sensor for saccharide detection is described in this study. The detection is based on selective interaction between diols and aminophenylboronic acid (APBA) immobilized on a gold electrode. Glucose, fructose, and dextran (MW: 40 kDa) were tested with the system over wide concentration ranges (1.0 x 10−8 M - 1.0 x 10−3 M for glucose, 1.0 x 10−8 M - 1.0 x 10−2 M for fructose and 1.0 x 1
