Drug-Immobilizing Micellar Nanoreactor: An Intriguing Drug Stable Delivery Strategy
ACS MATERIALS LETTERS(2024)
摘要
Conflicting requirements of stable drug delivery and controllable rapid release are simultaneously required of tumor therapeutic platforms. However, reconciling the contradictory requirements remains a formidable challenge. Herein, we reveal an innovative, stable drug delivery strategy and the corresponding therapeutic modality without the requirement of drug release. With cooperating nonbonded interactions (pi-pi stacking, hydrogen bonding), a reversible cross-linking strategy, and a crystallization-driven self-assembly (CDSA) process, the drug-immobilizing micellar nanoreactors are established with intriguing individual crystalline core-corona micellar structures, which can achieve long-term stability, small molecular exchange performance, and potential therapeutic benefit while bypassing the drug release. We believe that these will provide a new prospect for applications of stable polymeric micelles that circumvent the reconciling concern of release.
