In Vivo Tumor Targeting Of Gold Nanoparticles Effect Of

Jun 26, 2015· This decrease in AUC may be explained by the targeting effect of the peptides drawing the gold nanoparticles out of the plasma and into the tumor at 24 h. Thus we can conclude that PEGylation alone or peptide conjugation alone significantly decreased the clearance of gold nanoparticles so they were retained in the plasma volume.
