Use of hydrogels for biosensors having elevated sensitivity

摘要

The invention relates to measures for determining glucose and for diagnosing diseases that are based on impaired glucose metabolism. In particular, the invention relates to the use of a polymer-based hydrogel comprising at least one water-soluble polymer in a sensor in order to concentrate a dissolved glucose-binding protein, wherein the at least one polymer is able to interact with the glucose-binding protein and wherein the glucose-binding protein is present in a complex together with a ligand.
