Photolithographic hydrogel
WebPhotolithographic methods have produced hydrogels by the direct exposure of the polymer solution to UV radiation to produce micro-patterned scaffolds with feature sizes in the range of 50 m or more. However, the photolithographic techniques have had limited capability in producing three dimensional WebChemically, this highly accessible photolithographic gel shaping approach has been achieved through either: (1) phototriggered photopolymerization/covalent crosslinking (which typically formed covalently crosslinked gels);41,44-46 or (2) photoactivated changes in the ionic crosslinking and/or ionization (which occurred through either a ...
