The present invention provides compositions, systems, and methods employing cleavable polymeric micelles. For example, provided herein are compositions comprising micelles that contain a hydrophobic agent (e.g., metal nanoparticles and/or therapeutic agent), where the micelles are formed from a plurality of amphiphilic polymer molecules that comprise a hydrophilic polymer and a hydrophobic polymer, where the hydrophobic polymer comprises a cleavable Furan-Maleimide adduct. Also provided herein are methods of administering such compositions to a subject and treating a localized area of the subject with a device that emits heat, NIR light, and/or alternating magnetic current such that at least some of the micelles inside the subject near the localized area are disrupted (e.g., releasing a therapeutic agent).
本发明提供了使用可切割聚合物胶束的组合物、系统和方法。例如,本发明提供了包含疏水剂(例如金属纳米粒子和/或治疗剂)的胶束的组合物,其中胶束由包含亲水性聚合物和疏水性聚合物的多种两性聚合物分子形成,其中疏水性聚合物包含可切割的呋喃-马来酰亚胺加合物。本发明还提供了将这种组合物给予受试者并使用发热装置、近红外光和/或交替磁电流治疗受试者局部区域的方法,使得受试者体内靠近局部区域的一些胶束被破坏(例如释放治疗剂)。
