Gold Nanorod Bioconjugates for Active Tumor Targeting and Photothermal Therapy
Figure 2
TEM images of nanorod conjugation to antibody before PEGylation versus PEGylated nanorod conjugation to antibody. (a) Nanorods first conjugated to anti-EGFR antibody then PEGylated; (b) Nanorods first PEGylated then conjugated to anti-EGFR antibody; (c) PEGylated nanorods without antibody or crosslinker present. All scale bars shown are 100 nm.
