Y-Shaped Ligand-Driven Gold Nanoparticles for Highly Efficient Tumoral Uptake and Photothermal Ablation

We report functional gold nanoparticles (AuNP) with antibody-like ligands. These particles consist of Y-shaped ligands and AuNP. Transferrin (Tf) and Tat peptide were linked to each head of a Y-shaped poly(ethylene glycol) (PEG)-containing dopamine at one tail site. Also, Y-shaped ligands (with Tf and Tat peptide) were anchored to the surface of the AuNP as the result of noncovalent conjugation of dopamine and the AuNP. Interestingly, the...
