Cell viability is not affected by honey AuNP treatment.

Honey AuNPs exhibited nominal cytotoxicities on THP-1-derived macrophages at concentrations up to 100 μg/mL (p > 0.001). Combined results are reflective of three independent assays involving 24-hour exposure of macrophages to increasing concentrations of the honey mediated AuNP variants. Error bars represent +/- SE.
