Figure 11.

Fluorescence microscopy images of human cells derived from colorectal carcinoma (CaCo-2) treated with oxaliplatin-containing PLGA nanoparticles coated with anti-CD133 antibody conjugated to Alexa Fluor 488 (PLGA_OXA_Ab) and co-stained with anti-CD133 Atto 565. The CaCo-2 cells were treated with 90 µg·mL⁻¹ concentration of the PLGA_OXA_Ab for 30 min. From left: bright-field images of the cells; fluorescence emission of cells treated with PLGA_OXA_Ab; cells stained with anti-CD133-Atto 565; merge of the fluorescence images. The scale bars correspond to 20 µm.
