μCapsul™ controlled-release polymer

μCapsul™ is a bioabsorbable copolymer consist of mPEG and poly(lactide-co-glycolide). The defining feature of μCapsul™ is its temperature reversible sol-gel transition. Cool μCapsul™ appear in liquid form and alter to gel form in body temperature.

In the gel state, the highly lipophilic and network structure of the μCapsul™ allow it to become an efficient vehicle for localized administration of protein and small molecules, especially for hydrophilic factors. By maintaining these factors a high local concentration, we create a reservoir for these factors and can be released slowly over time.
