Outline of Final Research Achievements

For future cancer treatment with noninvasive hyperthermia technique, we have successfully produced self-propagating exothermic nanoparticles made of silica and titanium. First, the slips with silica nanopowders, polystyrene balls and pure water were atomized. Then, the atomized slips passed through furnaces; consequently porous silica nanoparticles could be made. By changing several parameters, it was possible to control the particle’s size, pore size, and porosity. With molten salt electrochemical processes, oxygen content in the silica particles could be reduced to around 27at%. Ti-coated silica nanoparticles could show self-propagating exothermic reaction.
