摘要: 在深化新医科建设,培养交叉学科高素质人才的战略背景的指引下,本文构建了一种面向药物递送前沿的综合教学实验,将超分子化学的理论知识与纳米医学实践深度融合。研究以二氢卟酚e6和替莫唑胺为模型药物,通过超声辅助超分子组装技术制备纳米递药体系,系统探究不同药物比例对纳米递药体系性能的影响。本实验利用聚集诱导荧光淬灭现象确定了超分子组装的成功进行,使用动态光散射表征了纳米递药系统的流体动力学粒径与Zeta电位,并通过紫外分光光度法测定药物包封率。本实验立足于解决当前常见纳米递药系统载药量低、辅料使用过多带来的潜在风险,采用无需辅料的超分子组装技术制备纯药物纳米颗粒。该实验操作简单,原理明确深入,且具有良好的可拓展性,有助于使学生掌握纳米递药系统研发核心技能,同时加深学生对纳米递药系统的理解,为培养“懂原理、擅创新、重实践”的新医科复合型人才提供了可推广范式。

Abstract: Guided by the strategic initiative to advance “New Medical Science” education and cultivate high-quality interdisciplinary talents, this study developed an integrated teaching experiment that bridges cutting-edge drug delivery research with practical nanomedicine applications. The experiment synergistically combines theoretical knowledge of supramolecular chemistry with hands-on practice, employing chlorin e6 and temozolomide as model drugs to prepare a nano-drug delivery system through ultrasound-assisted supramolecular assembly. We systematically examined how varying drug ratios affect the system’s performance. Successful supramolecular assembly was verified by aggregation-induced fluorescence quenching, while dynamic light scattering (DLS) characterized the system’s hydrodynamic size and zeta potential. Drug encapsulation efficiency was quantified using ultraviolet spectrophotometry. This innovative approach overcomes limitations of conventional nano-drug delivery systems, such as low drug-loading capacity and excipient-related safety concerns, by producing pure drug nanoparticles through excipient-free supramolecular assembly. With its straightforward protocol, well-defined scientific principles, and excellent scalability, this experiment effectively equips students with core competencies in nanodrug delivery system development while enhancing their conceptual understanding. It serves as an exemplary model for training interdisciplinary “New Medical Science” professionals who thoroughly comprehend fundamental principles, demonstrate innovation capabilities, and value practical application.
