超离液硼簇与季铵阳离子聚合物组装微粒用于胞质蛋白递送
Design Principles of Microparticles Based on Superchaotropic Boron Clusters and Quaternary Ammonium-Based Cationic Polymers for Cytosolic Protein Delivery
AI 导读
研究显示，超离液阴离子硼簇 B12Br122− 可与多种季铵基阳离子聚合物组装成载蛋白微粒（BPMs），不受聚合度、结构或拓扑限制，微粒被细胞内化后将蛋白释放到胞质。递送行为可通过聚合物种类、聚合度和浓度调节，适配不同分子量与等电点的蛋白；而质子化 N−H 基团作为竞争性氢键供体的叔铵聚合物则难以形成 BPMs。作者据此把季铵基团确立为超离液硼簇蛋白递送载体的重要设计要素。
推荐理由
原文比较了季铵与叔铵阳离子聚合物与硼簇组装成微粒的差异，为胞质蛋白递送载体的设计提供了可参考的结构判据。
创新点
原文指出超离液性可绕开现有载体对静电或疏水互补性的依赖，并进一步把季铵基团识别为硼簇与阳离子聚合物组装载蛋白微粒的关键结构要素，同时给出叔铵因 N−H 竞争氢键而组装不良的对照。
