Achieving traceless ablation of solid tumors without recurrence by mild photothermal-chemotherapy of triple stimuli-responsive polymer–drug conjugate nanoparticles

and a single dose of mild NIR irradiation, this simple and mild PT-CT treatment achieved a non-discerned tumor on the sixth day, and traceless and complete ablation of a solid MCF-7 tumor without recurrence within 50 days, opening up a new avenue for precise cancer therapy with the potential for real applications.
