PHOTOPOLYMERIZABLE MATERIALS FOR BIOCOMPATIBLE IMPLANTABLE MATRICES

The review considers photopolymerizable compositions based on biocompatible polymers for regenerative medicine. Assessment of the physical-mechanical and biological properties of photopolymerizable polymeric matrices, polyethyleneglycol, lactic acid, collagen, and hyaluronic acid, as well as of the effectiveness and toxicity of various photoinitiator supplements has been performed. Mechanical properties and degradation rate of the photopolymerizable matrices are ensured by selection of proportions of methacrylated mono-, oligo-, and polymers these consist of, while their toxicity largely depends on the photoinitiator systems used. It has been concluded that it is necessary to search for and develop the methods to obtain photopolymerizable polymeric matrices by using the compounds capable of initiating radical polymerization with lower toxic effect.
