Cell adhesion of RF/6A cells was not influenced by AuNPs. BCECF-labeled cells were treated with DMSO or nanogold for 30 min. They were then seeded and allowed to adhere to plates with precoated fibronectin (fn) (15 µg/mL) at 37 °C for 1 h. Fluorescence was measured using excitation and an emission wavelength of 485 and 535 nm, respectively. The results are expressed as a percentage of control and represent the mean ± standard errors (SE) of three independent experiments.
