In vitro wound assay of human keratinocyte cells treated with AuNP (5 μg l⁻¹), AuQurNP (5 μg l⁻¹), or pure quercetin (15 ng ml⁻¹) for different time periods (0, 4, 8, 16 h). Non-treated cells were used as control. Black, green, and red lines depict the start, end-point of cell migration, and migratory cell edge, respectively (magnification:10X).
