• Note (General): 共著：Ko Nakanishi, Shigeaki Abe, Shuichi Yamagata, Yasuhiro Yoshida, and Junichiro Iida; We investigated in controlled dye-release behavior of nanosized silica particles containing nanocavities (Nanoporous silica, NPS). To determine this, NPS were mixed with glass ionomer cement (GIC), which is a medical material used as a matrix. The dye-release behavior was observed using a UV-visible spectrometer. After cationic dye was charged into GIC pellet containing NPS, the pellet could gradually release cationic dye for up to two weeks. To understand the dependence of electric charge on the dye-release behavior, three types of dyes with different charge were also investigated. Dyes having a neutral or negative electric charge were quickly released from the pellet within a couple of days. These results suggest that the nanocavities present in NPS can selectively bind cationic dyes and allow for their gradual release. This result reveals the excellent sustained dye-release property of NPS.; (主査) 特任教授 飯田 順一郎, 教授 吉田 靖弘, 教授 佐野 英彦; 歯学研究科（口腔医学専攻）
