콜로이드 시스템 집적 연구실

Colloidal particles have been used as model system for atomic structures as well as building blocks for photonic crystals. My main research interests are in the synthesis of new colloidal particles and their structures by self-assembly which would be great model system for understanding even more complex biological structures. Using colloidal particles or micelles as templates, macro- or mesoporous materials could be prepared which is now investigated as efficient host materials for drug delivery or colorimetric sensor dye. Porous particles were also implemented for new bioadhesives on hydrogels or biological tissues. Ionic liquid (block co-) polmyers are synthesized and assembled into bicotinuous porous polymer films for solid electrolytes of lithium ion battery. Lipid nanoparticles are prepared by self-assembly for gene delivery such as DNA, mRNA as vaccine systems. Gold nanospheres are synthesized by chemically etching octahedron gold nanoparticles with polyDADMAC and assembled into clusters or crystals, which can be utilized as metamolecules or metamaterial film, respectively. Colloidal crystals or glasses may show angle-dependent or independent structural colors in UV, visible or IR region depending on the interparticle distance or particle diameter.
