Induction of single-strand breaks (SSB) and base damage recognized by formamido-pyrimidine glycosylase (FPG) in HepG2 cells treated with the combination of AgNPs with AuNPs (A), CdTeQDs (B), TiO₂NPs (C), and SiO₂NPs (D) for 2 h. Mean ± SD, n = 3. * denotes a statistically significant difference from the unexposed control, P < 0.05. # denotes a statistically significant difference between observed and expected values, P < 0.05.
