摘要:
The present invention provides materials that have high glucose and oxygen permeability, strength, water content, and resistance to protein adsorption. The materials include an interpenetrating polymer network (IPN) hydrogel that is coated with biomolecules. The IPN hydrogels include two interpenetrating polymer networks. The first polymer network is based on a hydrophilic telechelic macromonomer. The second polymer network is based on a hydrophilic monomer. The hydrophilic monomer is polymerized and cross-linked to form the second polymer network in the presence of the first polymer network. In a preferred embodiment, the hydrophilic telechelic macromonomer is PEG-diacrylamide, PEG-diacrylate or PEG-dimethacrylate and the hydrophilic monomer is an acrylic-based monomer. Any biomolecules may be linked to the IPN hydrogels, but are preferably biomolecules that support the growth of cornea-derived cells. The material is designed to serve as a corneal prosthesis.
