| (a) A molecular jackhammer (blue) attaches itself to a cancer cell’s lipid bilayer lining. When stimulated with near-infrared light, it vibrates strongly, causing the cell membrane to tear open. (b) Dye entering and staining nucleus of the membrane-disrupted A375 melanoma cells visualized by fluorescence confocal microscopy. Scale bar = 25 microns.
