Viability of cells (%) treated with non-ionic-, zwitterionic-, cationic-, anionic-PPE micelles, zwitterionic-, cationic- and anionic-PPE SCKs.
The values are presented as mean ± SD of at least triplicates. The graphs that present Lipofectamine, PEI, Cremophor-EL, the degradation products of the various PPE-based nanoparticles and various combinations of nanoparticles are in the Supporting Information (Figure S5).
