Analysis of a breast cancer cell line (MDA-MB-231) for short (15 minute) and long (60 minutes) incubations with FDG. a) Fluorescence image of a subsection of the droplet array superimposed on a bright-field image. The green droplets were incubated with FDG for 60 minutes while blue droplets were incubated for 15 minutes and allowed to efflux for 45 minutes. Individual cells are marked in red. b) Radioluminescence image superimposed on a bright-field image. Intensity ranges from blue for low counts to red for high counts of radiolabels and primarily coincides with the position of long incubation cells. c) Analysis of the number of observed FDG molecules for single cells with long and short incubation. The average value is indicated by a red line. The standard deviation and the 95% confidence interval are indicated by a blue and red bar, respectively.
