多功能胶束纳米粒
当前位置:首页 > 研究方向 > 多功能胶束纳米粒

聚合物胶束和纳米粒为疏水抗癌药物(例如阿霉素、紫杉醇、5-氟尿嘧啶等)的肿瘤靶向释放提供了重要的技术平台。目前,已有多个品种的聚合物胶束和纳米抗癌药物分别进入癌症治疗临床研究。然而,由于胶束纳米药物存在体内稳定性差、循环时间短、肿瘤细胞内吞效率低、胞内药物释放慢等瓶颈,肿瘤临床疗效没得到显著提高。我们发展和研究了不同策略,如设计了还原敏感可逆交联的生物可降解胶束、结合功能性表面活性剂和透明质酸涂层制备了多功能PLGA纳米载体等,巧妙解决了聚合物胶束纳米药物在体内传输过程中面临的挑战,有力增强了肿瘤治疗效果,并降低了系统毒副作用。
