Overview of Research

This research group is concerned with the construction of hierarchical molecular devices by the combination of nanosize molecular assemblies with micro size structures derived from dissipative processes. The following themes are in progress.
1) Development of novel drug delivery system using nanostructures
2) Control of self-assembly of nanoparticles and creation of functions
3) Development of supersensitive gel based plasmonic biosensors
4) Development of high efficient nanoparticle vaccine



The staff support you to improve your logical thinking skills that will be useful even after you enter the workforce.
