a) Schematic of the structural changes of amNR under the application of a magnetic field. b) Schematic illustration of the amoeba‐like nanorobot (amNR) for whole‐process active drug transport. First, the amNRs actively extravasated and penetrated into deep tumor tissue via magnetically driven deformation. Then, the acidic microenvironment of the deep tumor tissue uncovered the masked ligand (transactivator of transcription (TAT) peptide) of the amNRs for active tumor cell uptake. Next, the AMF triggered intracellular DOX release from the amNRs. Finally, the deformable amNRs achieved whole‐process active drug transport for superior antitumor efficiency with the assistance of magnetic field application.
