This invention discloses a photoactivated nanoparticle-based drug delivery material for immunoadjuvants, its preparation method, and its applications. The drug delivery material is constructed from photosensitizer monomers, crosslinking monomers, and immunoadjuvant prodrug monomers within a confined space of a nanoemulsion via a copper-free click polymerization reaction to form crosslinked polymer nanoparticles. The nanoparticle size is controllable, and the composition is precisely defined. Under physiological conditions, the drug delivery material exhibits good colloidal stability and high drug loading. Upon near-infrared light irradiation, the generated ROS can cleave the thioketone bonds, causing the nanoparticles to depolymerize and achieving photo-triggered, controllable release of the immunoadjuvant. Under photodynamic action, this drug delivery material efficiently generates reactive oxygen species to induce immunogenic cell death in tumor cells. Simultaneously, the released immunoadjuvant activates the TLR7 / 8 pathway, promotes dendritic cell maturation, and enhances the systemic anti-tumor immune response, thereby inhibiting the growth of tumors in situ and at distant sites, and reducing the risk of metastasis and recurrence.
