Abstract

Methods of preventing adhesion between issues are provided that utilizes in situ crosslinked biomaterials. The biomaterial contains at least the crosslinked product of two biocompatible, non-immunogenic components having reactive groups thereon, with the functional groups selected so as to enable inter-reaction between the components, i.e., crosslinking. Exemplary uses for the crosslinked compositions include preventing adhesions following surgery or injury, and preventing scar tissue formation.
