Substantially non-adhesive hydrogels are useful as wound dressings, wound barriers, therapeutic drug delivery devices and the like. The substantially non-adhesive hydrogels are synthesized by a method that comprises irradiating a solution comprising a biological polymer that is biodegradable and biocompatible, using ionizing radiation, whereby free radicals of the biological polymer are formed and cross-linking occurs between the biological polymer radicals to provide the hydrogel. |
