About the Lab

Molecular & Interface Engineering Laboratory

Our major interests are focused on the colloid and interface phenomena and magnetic and conductive materials of graft copolymers, metal oxide and carbon based materials, whose structures are composed of polymer and surfactant micelles, LC and lipids layers, nanogels, templates, metal oxide nanoparticles, and layered structures. For biomedical and industrial applications, developed are nanodoctor carriers, contrast agents, super or pseudocapacitor, and display materials.

Scope of Research

Nanoparticles for theragnosis and cosmeceutics


- Nanodoctor delivery

  Biocompatible graft copolymers of poly(amino aid) derivatives and their self-aggregates in aqueous solutions have been studied for anticancer drug carriers and cosmetics by conjugating specific functionalities like cell-penetrating peptides (CPPs), or antibodies, i.e., magnetic nanoparticles for MRI contrast agent and nano-bubbles for ultrasound contrast agent.


- Stimuli-responsive and valve membranes

  Stimuli-responsive nangels actuated by temperature, pressure, pH or direct contact are fabricated for gates, membrane or triggering devices. The phase volume transition of microparticles of PNIPAM in temperature and those of PAA by electrical field were investigated. Valve membranes are developed to control the flux by changing temperature.


- Colloidal mucoadhesive materials

  Mucoadhesive alginate microparticles - pig mucin interaction, and smell and gas sensor were investigated. The specific adsorption of biomaterials was investigated with SPR for recognizing antibody-antigen, or receptor-ligand interaction.


 

 

 

■ Layered structures for energy conversion and storage


- Layered structures

  Ordered arrays of mesoporous structures of metal oxides and carbon materials are derived via supramolecular assemblies of surfactants, whose composites provide high performance for magnetic or conductive nanoparticles and layers in energy conversion and storage. Especially, low cost materials for pseudocapacitor, magnetic inks and radar absorbing materials are investigated.


- Alignment layers and dynamic grating

  LCD requires new methods of aligning liquid crystals and backlight. Real-time holograph using layered liquid crystal PR cells, were examined by introducing conductive dopants C60 and graphene.
