Density of surface charge is a more predictive factor of the toxicity of cationic carbon nanoparticles than zeta potential

Abstract Background A positive surface charge has been largely associated with nanoparticle (NP) toxicity. However, by screening a carbon NP library in macrophages, we found that a cationic charge does not systematically translate into toxicity. To get deeper insight into this, we carried out a comp...
