Paper Abstract

This paper presents a characterization of a biocompatible, PEG-DA based photopolymer, using a holographic method. This technique allows quick and simple measurement of polymerization time. A correlation of the optical method with gel fraction is presented. The dependence of polymerization time on irradiation intensity and photosensitizer concentration is discussed. A range of photosensitizer concentration giving fully polymerized hydrogels is demonstrated, and an optimal concentration is found. The use of different photosensitizers is assessed in order to develop new photopolymers for biomedical applications.
