第一部分中空介孔普魯士藍(lán)納米粒的制備、表征及釋藥研究目的制備了一種具有優(yōu)異生物相容性/穩(wěn)定性的多功能納米粒——裝載溫敏性相變材料全氟己烷和抗腫瘤藥物阿霉素的中空介孔普魯士藍(lán)納米材料(perfluorohexane and the doxorubicin-encapsulated hollow mesoporous Prussian Blue nanoparticles,HMPBs-DOX/PFH),檢測(cè)其物理性質(zhì)、化學(xué)性質(zhì)、光學(xué)性質(zhì)、穩(wěn)定性、藥物釋放性能以及相變性能。方法采用選擇性刻蝕法和藥物吸附法依次制備出HMPBs和HMPBs-DOX,檢測(cè)其形態(tài)結(jié)構(gòu)及化學(xué)組成。然后,采用真空灌注法制備出HMPBs-DOX/PFH,對(duì)其粒徑、電位、載藥率以及光吸收性等性能。通過光學(xué)顯微鏡分別檢測(cè)該多功能納米粒的相變效應(yīng)。檢測(cè)HMPBs-DOX/PFH分別在不同p H值(4.6,6.0,7.4)緩沖液和HIFU作用前后的藥物釋放率,并檢測(cè)生物組織中HMPBs-DOX/PFH在HIFU作用前后的藥物釋放情況。最后采用高效液相色譜法檢測(cè)DOX的熱穩(wěn)定性。將HMPBs-DOX/PFH與MDA-MB231細(xì)胞...
