Abstract:
1. A method to weld tissue together, comprising the steps of: (a) applying to at least one tissue a composition comprising at least one photosensitizer and at least one proteinaceous compound or lipid wherein at least one covalent bond conjugates said photosensitizer to said proteinaceous material or said lipid; and (b) irradiating said composition with electromagnetic energy; wherein said photosensitizer is a cationic azine mon-azo dye, a tri-arylmethane dye, a chlorine, a tetrapyrrole, a cationic thiazine dye, or derivatives thereof; and wherein said irradiating promotes adhesion of said tissue to at least a second tissue and wherein said composition comprises at least a second proteinaceous compound not covalently conjugated to said photosensitizer.
