Fig. 3. Cellular fluorescence images of prodrug Pro-DC-treated MCF-7 cells. The cells were incubated with Pro-DC (1 μM) for 2 h and then irradiated with a blue LED for (a) 0 min, (b) 10 min, (c) 30 min and (d) 60 min. (e) Relative pixel intensity (n = 3) from the images. The pixel intensity from the images. The pixel of (d) is defined as 1.0. Scale bar 10 μm. λExt = 650 nm; λMon window of 530–710 nm.
