Optical bright-field images of SGS internalization within Hep3B cancer cells across a 17-h period. Two SGS particles of diameters approximately 2 μm, indicated by red and blue arrows, are shown to be internalizing approximately 10 h after exposure to SGS of concentration 10 μg/ml. The two cells visible seem to be undergoing cell division. (A to H) Time points at 10 to 17 h, in 1-h increments.
