AgNPs induce cell transformation in BEAS-2B cells. Soft agar cell transformation and colony forming efficiency was determined after 3 and 6 weeks of exposure to 10 nm and 75 nm AgNPs (1 µg/mL). Results are expressed as total number of colonies in soft agar after 3 weeks (A) and 6 weeks (B). The colony forming efficiency results (C) were used to calculate the overall transformation frequency (D). Results are shown as mean values ± S.D., n = 3 (*p < 0.05).
