Dr. Thao Nguyen
I've designed and constructed a PEDOT nanotube patch that is capable of fast and controlled transdermal delivery. The theory behind the fast release is the electronic attraction and repulsion between the positive PEDOT backbone and negatively charged model drug molecules. We were able to achieve in vivo release within 10 minutes and drug saturation in the blood system within 30 minutes. The nanotube patch is ideal as a universal drug delivery system since we are able to fine tune the length and wall thickness of the nanotubes and functionalize the nanotubes accordingly, to upload and release drugs of interests.

The nano-dimensions and synergic properties of MnO2 and PEDOT enable the coaxial nanowires to have high energy densities at high power densities.

Dr. Sang Jun Son
Spherical shape of nanoparticles has been used for the most nanobiotechnology because spherical shape is easy to make. However, when multifunctionality is especially required on their surfaces, spherical nanoparticles still need to be improved for controlling multifunctionalization of surfaces, and their environmental compatibility due to the structural limitation of spherical particles. Since it has a single surface, every surface modification for the multifunctionality should take place at the same surface. This may lead to malfunction or interruption between the multifunctional components. In that sense, tubular structure of nanoparticles has become highly attractive for the multifunctional nanoparticles due to their structural attributes, such as the distinctive inner and outer surfaces, over conventional spherical nanoparticles. Inner voids can be used for capturing, concentrating, and releasing species ranging in size from large proteins to small molecules because tube dimensions can be easily controlled by the template synthesis. In addition, inner and outer surface modifications can be performed by totally separated processes so that inner surface modification can be carried out just to satisfy requirement in deliver of biomolecular cargos without any consideration of outer surface
