Fig. 1: Schematic of cancer-cell stiffening using RDPNs@diABZIs boosts T-force-mediated killing for anticancer STING immunotherapy.

RDPNs@diABZIs nanoparticles, composed of the diselenide-bridged polyrotaxanes loaded with agonists diABZIs, generate robust anti-tumor immunity by synergistically enhancing T-cell intratumoral infiltration and T-cell force, thereby potentiating T-cell cytotoxicity.
