Progress in boronic acid-based fluorescent glucose sensors

Effective management of diabetes relies on the frequent monitoring of blood glucose concentrations. The current approach of blood sampling and glucose concentration determination in vitro presents many problems. Therefore, there is a drive for the development of non-invasive and continuous monitoring of glucose concentrations. The use of implanted glucose fluorescent sensors represents a promising approach. Due to its strong interaction with diol moieties, the boronic acid group often plays a critical role in the design of such glucose sensors. This paper reviews the progress in this area during the last ten years.
