Figure 6.
(a) The target cells (green) are HeLa cells with Alexa Fluor 488 fluorescence, and the background cells (red) are HeLa cells with Alexa Fluor 647 fluorescence. The target cells can be detected easily in all four different ratios of mixtures. (b) The comparison of the detected data and calculated pre-set data with different ratios of targeted cells to background cells.
