Confocal laser scanning microscopy [50] of (a) MCF-7 human breast cancer cells, (b) NIH-3T3 mouse fibroblast cells, and (c) MCF-10A human normal mammary epithelial cells incubated with aptamer-AgNC: (1) bright-field images; (2) AgNCs fluorescence images (red). Under the same procedure, there were no detectable emissions from the control cells. Reprinted with permission from Li et al. [50]. Copyright (2012) American Chemical Society.
