Controlled release of bioactive molecules from porous materials regulates cellular functions

Living cells are recognized as an ultimate assembly of molecules. As its active matter, a living cell regulates its function by intracellular signalling molecules and communicates to each other by extracellular signalling molecules. We develop porous materials that accommodate important signalling molecules (nitric oxide, carbon monoxide, or glutamic acid) and give materials a chemical trick to release these signalling molecules by external trigger. This new type of porous materials are demonstrated to directly regulate the biological activity of living cells. We are currently developing these materials for therapeutic applications.
