Effect of CNPs concentration and incubation time on the intracellular K+ accumulation in BY-2 cells (a) and BY-2 cell fresh biomass (b). K+ content was measured in medium containing 46.88 mM K+, except for control group. Error bars indicate the standard error of the mean (n = 4). Asterisk (*) indicates significant difference compared with control group and group containing 46.88 mM K+ without CNPs (p < 0.05). c, d Relationship between cell fresh biomass and K+ accumulation in cells using an Bivariate statistical model with cell fresh biomass as Y variable. c The Bivariate model is highly significant (p < 0.026, R2 = 0.865). d The Bivariate model is no obvious significant (p > 0.05, R2 = 0.718)
