Figure 7: DNA strand breaks after treatment of PBCEC and PCPEC with AgEO- and AgCitrate-NPs for 24 h. A) DNA strand breaks in PBCEC. As positive control PBCEC were treated with H2O2 (100 μM, 5 min) which induced 7181 ± 1557 DNA strand breaks. B) DNA strand breaks in PCPEC. As positive control PCPEC were treated with H2O2 (100 μM, 5 min) which induced 8429 ± 1169 DNA strand breaks. The values are represented as mean ± SEM.
