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). |
