Effects of Pt‐NPs on He‐CAP‐induced MMP loss in U937 cells, as determined by flow cytometry using TMRM staining (A) Representative flow cytometric histogram of MMP loss. (B) Increased loss of MMP was observed in the cells treated with the He‐CAP alone which was decreased in the presence of Pt‐NPs. Data are presented as mean ± SD. **P < 0.005 as compared with He‐CAP treatment alone. Data shown are representative of five independent experiments. He‐CAP, Helium‐based cold atmospheric plasma; MMP, mitochondrial membrane potential.
