Abstract
A hydrogel material composition includes: (1) an alginate (or other cross-linking polymer) material; (2) an optional α-hydroxy carboxylate material; and (3) an iron cation material. The hydrogel material composition with or without the α-hydroxy-carboxylate material may be used in a photolithographic imaging application or a photorelease application within the context of a photoirradiation induced reduction/oxidation reaction of an iron (III) cation material to form an iron (II) cation material.
