From: Smart antimicrobial efficacy employing pH-sensitive ZnO-doped diamond-like carbon coatings
Metabolic activity of cells (type L929) treated with different fractions of implant-conditioned Hank’s balanced salt solution (A) or defined concentrations of ZnCl2 (B). LD50 values derived from (B) indicate a roughly linear correlation between the pH of the buffer and the toxicity of ZnCl2.
