Hydrogel Attached to Backing and Method for Making Same

摘要

The present invention relates to a method of making a preformed hydrogel attach to a polymer backing comprising exposing a surface of the backing to an activated gas and depositing the preformed hydrogel on the exposed surface of the backing, and hydrogel products so formed. This hydrogel product can be used as an active ingredient delivery device, a wound cover and a diagnostic tool. It advantageously replaces hydrogel products using chemicals as adhesive agents.
