Bright field images of four cell lines that were incubated with Her-PEG GNRs in-vitro. Slides were stained using a sliver staining kit to visualize gold nanorods as dark spots under conventional bright field microscopy. A: MCF-7 (Breast cancer but no HER2/neu expression→ no staining), B: Fibroblast (no HER2/neu expression → no staining), C: SK-BR3 (over expression of HER2/neu), D: BT-474 (over expression of HER2/neu), E: MCF-10A (normal breast, no HER2/neu → no staining). Dark counts were determined manually using cell count plugins and Image J software.
