The overlay of differential interference contrast (DIC) and fluorescence images of HeLa cells that contain (a) compound 41 with no supplemental ZnCl2, (b) 41 in the presence of 50 μM of ZnCl2, (c) compound 42 with no supplemental ZnCl2, and (d) 42 in the presence of 50 μM of ZnCl2. The excitation source is a 405-nm diode laser. Emission window: 500–530 nm for panels (a) and (b); 580–680 nm for panels (c) and (d). Scale bar: 10 μm. Panels (a) and (b) are reproduced from Ref. [125] with permission from John Wiley and Sons; panels (c) and (d) are reproduced from Ref. [126] with permission from The Royal Society of Chemistry.
