HER2 Breast Cancer Tumor Cells

Caption

These photomicrographs demonstrate the dramatic impact of using nanotubes to selectively locate and destroy HER2 breast cancer tumors. Tumor cells on the left were treated only with antibodies against the HER2 protein and then irradiated with near-infrared light. Those on the right were treated with a complex of antibodies and nanotubes and then irradiated. Both cultures then were stained with fluorescent dye -- green color indicates live cells while red marks areas where cell have been killed.
