| Outline of Final Research Achievements |
Colloidal mesoporous silica nanoparticles (CMS) as bioimaging carriers possessing various internal nanospaces were prepared and the pore clogging of outer surfaces of CMS was successfully realized. The pore size of CMS was controlled in the range from 4 nm to 8 nm using controlled templating. Hollow siloxane-based nanoparticles with high colloidal stability were also prepared when CMS were covered with ethenylene-bridged organosiloxane. The outer surfaces of CMS containing thermoresponsive dyes were successfully covered by the simple addition of tetraalkoxysilane under controlled pH conditions. The thermally responsible property of the dye in the internal nanospace of CMS was retained after the pore clogging.
