Outline of Final Research Achievements |
In this research, to develop stimuli-responsive drug delivery carriers, we explored surface ligand molecules that can induce the self-assembly of metallic nanoparticles, such as magnetic or gold nanoparticles in solutions. It was found that surface modification with a ligand molecule possessing a fluorinated oligoethylene glycol (SFL) induced spherical self-assembly of magnetic nanoparticles as well as gold nanoparticles. Interestingly, the glucose-terminated SFL molecules enabled the formation of size-segregated structures when used with a mixture of gold nanoparticles of two different diameters. Gold nanoparticles showing thermal responsiveness were also successfully created.
