Our research group brings together research from the field of polymer chemistry and nanoscience at the interface of biology, pharmacy, and biomedicine. Our group primarily focuses on the design and development of macromolecular nanoscale devices as multifunctional drug delivery nanocarriers, cellular imaging platforms, and tissue scaffolds for biological and biomedical applications. Our particular interests are the integration of nanostructured materials with biology and biomedicine to develop advanced bionanomaterials with multifunctionalities such as stimuli-responsive degradation (SRD). These materials can interface with biological processes as well as understand their biological functions, thus offering enormous potential for cancer research and treatment. Currently, we are developing two major bionanomaterials, each of which addresses critical problems in the areas of biomedicine:

  • SRD-based nanomaterials: self-assembled block copolymer-based nanocarriers, hydrogels, nanogels, fibers, and thermoresponsive polymers.
  • Multidentate block copolymer (MDBC)-stabilized organic and inorganic hybrids (magnetic nanoparticles, quantum dots, carbon nanotubes).

Furthermore, we have expanded our research scope to include the development of high-performance crosslinked materials for industrial applications.

  • High performance industrial materials: thiol-ene crosslinked materials and self-healable materials.
