Research Abstract

In order to apply Tetra-PEG gel for biomedical structural materials, we evaluated the biocompativility and drug releasing behavior, and introduced the biodegradability to Tetra-PEG gel. We confirmed the biocompatibility of raw material, gelation reaction, and formed gels. We investigated the release of model drugs from Tetra-PEG gels, and clarified the effect of mesh size on the drug releasing behavior. We designed the novel molecules and succeeded in the fabrication of biodegradable Tetra-PEG gels.
