Viability of NCTC 929, HeLa, and HepG2 cells after exposure to silver nanoparticles (AgNPs).

Notes: NCTC 929 (mouse fibroblasts), HeLa (human cervix adenocarcinoma), and HepG2 (human hepatocarcinoma) cells were pre-cultured for 24 hours, and then incubated at concentrations of 10, 5.0, 2.5, 1.25, 0.625, 0.312, and 0.156 µg/mL AgNPs (10 nm) for 24 hours. Cell viability was estimated by absorbance after uptake of neutral red.
