Abstract
The Invention relates to a stereo photo hydrogel formed by stereo complexed and photo cross-linked polymers, which polymers comprise at least two types of polymers having at least one hydrophilic component, at least one hydrophobic mutually stereo complexing component, and at least one of the types comprises at least one photo cross-linkable component, to a process of making stereo photo hydrogel comprising the steps of a. providing a mixture of at least two types of polymers having at least one hydrophilic component, at least one hydrophobic mutually stereo complexing component and at least one of the types comprises at least one photo cross-linkable component; b. stereo complexing the two types of polymers, thereby forming a stereo complexed hydrogel; and c. photo cross-linking the stereo complexed hydrogel using visible or UV irradiation, thereby forming the stereo photo hydrogel, to such polymers for use in such hydrogel, and to a pharmaceutical kit comprising same.
