Second Near‐Infrared Photothermal Semiconducting Polymer Nanoadjuvant for Enhanced Cancer Immunotherapy

Immunotherapy has offered new treatment options for cancer; however, the therapeutic benefits are often modest and desired to be improved. A semiconducting polymer nanoadjuvant (SPN II R) with a photothermally triggered cargo release for second near‐infrared (NIR‐II) photothermal immunotherapy is reported here. SPN II R consists of a semiconducting polymer nanoparticle core as an NIR‐II photothermal converter, which is doped with a toll‐like...
