Figure 3.
Images of HeLa cells directly after application of auto-fluorescent curcumin (10 µL of a CD-CC-NP aqueous suspension containing 1.8 µg CC were added to 100 µL well volume; red lining is due to artificial coloring for better visualization of cell morphology). The GFP channel is compared to the bright field image (magnification 40×). Inset: CC fluorescence is visible in all cells in the well, here imaged with a 10× objective.
