ECM molecule production by human fibroblasts was impaired after exposure to AuNPs. Cells treated with AuNPs at concentrations of 0.1, 1, or 10 μg/mL for 24 h were analysed using indirect immunofluorescence to detect laminin and collagen-1 production. Panels in (a) show laminin (green staining; upper panels) and collagen-1 (green staining ; lower panels) production in NP-treated cells. Magnification, 200×. Bar graphs in b and c show fluorescence intensity for laminin and collagen-1, respectively. Data have been presented as mean ± SEM. CTR: non-treated cells; *p < 0.05, **p < 0.01, ***p < 0.001
