PGCS-NPs (40 nm) with excellent photothermal activity are developed, on the surface of which affibody peptides with specific affinity for EGFR and many small gold dots (1-3 nm) are densely presented. The IV-injected PGCS-NPs into EGFR-expressing tumor-bearing mice successfully perform targeted and photothermal therapy of cancer. It seems that the small gold dots released from disassembled PGCS-NPs are easily removed and never cause in vivo toxicity problems.
