本發明包覆藥物的方式是以共沉澱方式合成氫氧基磷灰石並同時加入藥物分子(Doxorubicin, DOX),因此在氫氧基磷灰石殼層生成的同時也將藥物分子包覆在殼層當中,完成雙性明膠/氧化鐵/氫氧基磷灰石奈米核殼藥物載體,本發明所發展出的雙性明膠/氧化鐵/氫氧基磷灰石奈米核殼藥物載體,具有良好的酸鹼敏感特性,可利用環境酸鹼值的不同,迅速且精準的釋放大量藥物。而且此藥物奈米載體的核磁共振自旋-自旋弛緩速率為109 s-1mM-1Fe,證明具有核磁共振顯影的特性。因此,此磁性奈米載體非常適合當作核磁共振顯影自旋-自旋弛緩的顯影劑。 a type of pH-responsive amphiphilic gelatin assembled iron oxide / calcium phosphate core-shell (AGIO@CaP) nanoparticles formulation was developed for efficient delivery of anti-cancer drug (doxorubicin, DOX). Based on the formulation, the AGIO nanoparticles were coated with CaP by coprecipitation to from AGIO@CaP nanoparticles, and the drug molecules were encapsulated within the shell of CaP to regulate the release pattern. The advantage of the strategy is that the formation of CaP and loading of the drug occur simultaneously, which makes it possible to achieve high drug-loading capacity compared to traditional encapsulated techniques. The AGIO@CaP nanoparticles demonstrated a highly pH-sensitive controlled drug release behavior, could improve the efficacy and safety of drug delivery.
