A recently filed patent (Publication Number: US20230390452A1) describes a kit for preparing a photocurable liquid adhesive. The kit includes two containers, one containing a sterile liquid preparation with an aqueous liquid, polymers containing phenolic groups, and a photoactivatable metal ligand complex, while the other container holds an electron acceptor. The polymers containing phenolic groups can be natural or phenol-enriched polymers like collagen, gelatin, or collagen peptides with specific molecular weights. The electron acceptor is in dry powder form, and the sterile liquid preparation has a defined viscosity. The kit also includes means for shielding the liquid preparation from light that could activate the metal ligand complex.

Furthermore, the patent outlines a liquid adhesive composition that includes the photocurable liquid preparation, polymers with phenolic groups, the metal ligand complex, and an electron acceptor. This composition remains in a liquid state at 20°C. The patent also details a method for preparing the adhesive using the kit and applying it to a surface, followed by curing with visible light. Additionally, a method for manufacturing the kit involves sterilely filling the liquid preparation and providing the electron acceptor in a second container before packaging them together. The patent provides a comprehensive guide for creating and using a photocurable liquid adhesive, emphasizing the importance of specific ingredients and sterile conditions throughout the process.
