Dose-dependent absorption of CPN nanoparticles in Caco-2 (a) and NCI-H295R (b) cells. Fluorescence microscopy images of cells treated with increasing concentrations (20, 10, 5, 3, and 1 μM) of CPN and empty polymer (control). Increased fluorescence intensity in both cell lines indicate dose-dependent uptake of nanoparticles. CPN denotes curcumin piperine nanoparticles. Additional details for other nanoparticles are in supplementary figures S2 and S3.
