Cell viability in human colorectal cancer cells (Caco-2). Cell viability (%) of inulin nanoparticles loaded with quercetin (NQs), inulin non-charged nanoparticles (NBs), quercetin and inulin at different concentrations (4.3 to 0.134 μg/mL) in human colorectal cancer cells (Caco-2) after 24 h, determined by MTS assay. Values are expressed as mean ± SD. Controls are untreated cells. Significant differences among treatments in the cell lines were determined based on Dunnett multiple comparison test (p ≤ 0.05) where * control vs. NQs. Significant differences were determined based on the Student’s t-distribution (p ≤ 0.05) where ^ac represents NQs vs. quercetin.
