As an ideal platform for targeted drug delivery, nano-scale drug carrier should have multifunctionality and many other attributes, such as targeting moiety, drug uptake and releasing control, imaging capability, proper small size and size distribution, and non-toxicity. We are opening a new area in the nanomaterial field for the drug delivery through the synthesis of magnetic nanotubes by combining the attractive tubular structure with magnetic property.
We are investigating new electrochemical growth mechanisms of the conductive polymer nanotubes and metal nanotubes in cylindrical pores of a template. Using poly(ethylenedioxythiophene) (PEDOT) nanotubes, we have demonstrated the world-first moving-image speed in the electrochromic device with high optical color contrast, which has never been achieved simultaneously before.
