In this present study, original, biodegradable, biocompatible, non-immunogenic and non-poisonous folic acid (FA) decorated reductive-responsive starch-based microcapsules (FA-RSMCs) were designed and fabricated via the sonochemical method for targeted delivery and controlled release of hydrophobic drugs. A green hydrophobic fluorescent dye, Coumarin 6 (C6), was encapsulated into the FA-RSMCs as a substitute of hydrophobic drugs. The as-synthesized C6-loaded FA-RSMCs were characterized by DLS, SEM and TEM. The results indicated that the obtained C6-loaded FA-RSMCs had an appropriate size range and could enter into the bloodstream with their splendid stability. Moreover, C6-loaded FA-RSMCs showed a high selectivity to Hela cells, and a brilliant targeted drugs delivery and reductive-responsive release ability for hydrophobic drugs, particularly for hydrophobic anti-cancer drugs.
在本研究中，通过超声化学方法设计并制备了原始的、可生物降解的、生物相容的、非免疫原性和无毒的叶酸（FA）修饰的还原响应性淀粉基微胶囊（FA-RSMCs），用于疏水性药物的靶向递送和控制释放。一种绿色疏水性荧光染料香豆素 6（C6）被包封到 FA-RSMCs 中作为疏水性药物的替代品。所合成的负载 C6 的 FA-RSMCs 通过 DLS、SEM 和 TEM 进行了表征。结果表明，所得负载 C6 的 FA-RSMCs 具有合适的粒径范围，并具有出色的稳定性，可以进入血液循环。此外，负载 C6 的 FA-RSMCs 对 Hela 细胞表现出高选择性，并且具有出色的靶向药物递送和还原响应性释放疏水性药物的能力，特别是疏水性抗癌药物。
