A Near-Infrared-II Fluorescent Nanocatalyst for Enhanced CAR T Cell Therapy against Solid Tumor by Immune Reprogramming

A multifunctional nanocatalyst was prepared by encapsulating horseradish peroxidase-loaded Au/polydopamine nanoparticles and Ag2S quantum dots with CAR T cell membranes to improve the CAR T cell therapy in solid tumors.
