Hydrogel-based biosensors and sensing devices for drug ...

2016-10-28· Many hydrogel-based biosensors rely on a change to the equilibrium-swollen volume of the hydrogel to measure chemical or biomolecular changes in the sensing environment. One such example is an optical sensor fabricated by Tierney et al. . Hydrogel was adhered to the end of an optical fiber from which very sensitive swelling changes could be measured. Light was reflected at the fiber/hydrogel ...
