Ultra-small NIR-Responsive Nanotheranostic Agent for Targeted Photothermal Ablation Induced Damage-Associated Molecular Patterns (DAMPs) from Post-PTT of Tumor Cells Activate Immunogenic Cell Death

ABSTRACT: Theranostic nanoparticles (TNPs) is an efficient avenue that culminates both diagnosis and therapy into cancer treatment. Herein, we have formulated a theranostic nanocomposite (NC) with CuS being the ultra-small core component. To ensure stability to the NC, PEI was added which is a vital anchoring group polymer, especially on sulfide surfaces, and adds quality by being a better stabilizer and reducing agent. Additionally, to add stability, specificity, and added photothermal efficiency to the fabricated NC. In addition, encapsulation of indocyanine green (ICG), an efficient NIR absorber, and Folic acid (FA) were conjugated systematically, characterized, and analyzed for photo-stability. The photothermal conversion efficiency of the novel NC (CuS-PEI-ICG-FA) was analyzed at 808 nm, where
