Effect of Fe₃O₄ NPs on I_MEP recorded from RAW 264.7 macrophages. The experiments were conducted in cells bathed in Ca²⁺-free Tyrode’s solution. (A) Original traces of I_MEP obtained in the absence and presence of Fe₃O₄ NPs. The current trace labeled (a) is control, and those labeled (b) and (c) were obtained in the presence of 30 μg/mL and 100 μg/mL Fe₃O₄ NPs, respectively. The inset indicates the voltage protocol used. (B) Bar graph showing summary of the effects of Fe₃O₄ NPs (30 μg/mL and 100 μg/mL) on I_MEP recorded from RAW 264.7 macrophages (mean ± standard error of the mean; n = 6–10 for each bar).

Note: ^*Significantly different from control.

Abbreviation: Fe₃O₄ NPs, magnetite nanoparticles.
