Confocal microscopic visualization confirming the localization of the HER2 IgY-SWNT complex on the cell membrane of SK-BR-3 cells. From left to right, the panels are the brightfield image, DAPI channel image showing the nucleus, quantum dot (QD) channel image showing fluorescence from the HER2 IgY-SWNT complex, and an overlay of the three. The white bar represents 10 μm.
