Abstract:
A method for forming an implantable biosensor having a biocompatible coating, the method comprising coating the implantable biosensor with a hydrogel composition formed by admixing (a) a diisocyante, the diisocyanate comprising about 50 mol % of the reactants in the admixture; (b) a hydrophilic polymer selected from, the group consisting of a hydrophilic polymer diol, a hydrophilic polymer diamine and combinations thereof; and, optionally, (c) a chain extender, thereby forming the implantable biosensor having the hydrogel coating, wherein the hydrogel composition has a water pickup of at least about 120% by weight.
