A polybifunctional reagent having a polymeric backbone, one or more pendent photoreactive moieties, and two or more pendent bioactive groups. The reagent can be activated to form a bulk material or can be brought into contact with the surface of a previously formed biomaterial and activated to form a coating. The pendant bioactive groups function by promoting the attachment of specific molecules or cells to the bulk material or coated surface. Bioactive groups can include proteins, peptides, carbohydrates, nucleic acids and other molecules that are capable of binding noncovalently to specific and complimentary portions of molecules or cells.

Dans la présente invention, on divulgue un réactif polybifonctionnel ayant un squelette polymère, un ou plusieurs groupes latéraux photoréactifs et au moins deux groupes latéraux bioactifs. Ce réactif peut être activé pour former une matière en vrac ou peut être mis en contact avec la surface d'une biomatière préalablement formée, puis activé pour former un revêtement. Les groupes latéraux bioactifs servent à promouvoir la liaison de molécules ou de cellules spécifiques à la matière en vrac ou à la surface revêtue. Les groupes bioactifs peuvent inclure des protéines, des peptides, des hydrates de carbone, des acides nucléiques ou d'autres molécules qui peuvent se lier de manière non covalente à des parties spécifiques et complémentaires de molécules ou de cellules.
