Fig. 6From: Cobalt nanoparticles as novel nanotherapeutics against Acanthamoeba castellaniiCoNPs presented limited cytotoxicity to HeLa cells. Briefly, 100 µg/ml of CoNPs were added to HeLa cells and incubated for 24 h at 37 °C in a 5% CO2 incubator. The result of cytotoxicity for the most potent antiamoebic CoNPs, that is Co3(PO4)2, shows lower cytotoxicity when compared to 100 µg/ml of the antiamoebic drug chlorhexidineBack to article page
