Colorimetric sensors for saccharides

Colorimetric sensors for saccharides are of particular interest in a practical sense. If a system with a large color change can be developed, it could be incorporated into a diagnostic test paper for saccharides, similar to universal indicator paper for pH. Such a system would make it possible to measure o-glucose concentrations without the need of specialist instrumentation. This would be of particular benefit to diabetic patients in developing countries. 

Boronic acid-based biosensors to detect saccharides The recognition of saccharides, especially o-glucose, is of particular interest, owing to their correlation to diabetes and human cancers. The specific recognition of boronic acid for -diols provides a sensing selectivity. In the sugar sensors based on boronic acids (Figure 8), fluorescent, colorimetric, or electrochemical methods can be used as readout units.
