Research Theme

• For applying applying certain materal or process to biological systems, the material and process should be biocompatible.
• Under mild conditions, biological system can produce many organic/inorganic materials such as CaC03, Silica, Proteins.
• Blomimtic : imitating the structure or process in biological systems.

Silica In Diatom

• Diatom is encased within silica shell wall.
• Diatom can produce silica structure under a mild condition.
• Imitiating silica formation processin diatom.

Adhesive Protein In Mussel

• Mussel can attach on the certain surface even in an aqueous condition.
• Polydopamine-mimicking mussel protein can coat almost every substrate under a biocompatible condition.

Layer-by-layer

• Alternate deposition of positively charged polymer & megatively cherged polymer can make thin films.
• The method-coating the suface with polyelectrolytes in an aqueous solution under a mild condition.
