The functionality of biomaterial is determined by microstructure of molecular complex based on chemical structure of molecules and the characteristics of materials are depending on surface structure. The lab is interesting to develop functional biomaterials that could be applied as medical and polymeric biomaterials based on interaction between cell and materials.

Ongoing studies
The lab has nine projects in four parts including bone material. 
We currently applied 2 domestic and 1 international patents. We are studying differentiation of bone tissue with PNU-Fraunhofer IGB international institute and Maxillo-facial lab. 
Also we are doing research to develop drug delivery polymers for nature medicines with medicinal plant lab in PNU and to develop medical antihemorrhagic using bacterial product with microbiology lab. We are also developing natural polymeric material to cure winkles and to protect skin aging with molecular biology lab, which is on the step of preclinical trials.
