Fig. 4: Conditional and absolute internalization probability of microplastic particles into cells.
From: Nominally identical microplastic models differ greatly in their particle-cell interactions
a The conditional internalization probability displayed as a function of the ζ-potential of the particles indicates no correlation between the two parameters (Pearson’s R = -0.2, two-sided P = 0.6), whereas the absolute internalization probability (b) does (Pearson’s R = 0.9, two-sided P = 5.4 × 10−5). The internalization probability of particles coated with an eco-corona (MM-SW2, MM-SW4, MM-FW2 and MM-FW4) was calculated from the data published by Ramsperger et al.15. In (a), error bars represent standard error of mean of n = 3 replicates (for each replicate, 100 particle-cell interactions were analyzed). The error bars in (b) were propagated from the uncertainties in (a) and Fig. 3d. Source data are provided as a Source Data file.
