A Relative cell viability after 24 h of incubation with CDs at 0,05 g/L, CCDs at a 20:3 CD:PEI mass ratio and PEI at 0,016 g/L using the MTT assay. (n = 9, mean values ± SD. Student’s t-test was applied for statistical significance: * P < 0.05 *** P < 0.001. B Agarose gel electrophoresis of the complexes at different mass ratios
