The alteration of mitochondrial morphology and structure in macrophages stimulated by different coated AuNPs (5 μg/mL) for 24 h. A The fluorescence intensity of mitochondria (mean ± SD, n = 3) using the MitoTracker Red assay. B The number of tubular mitochondria (mean ± SD, n = 3). *p < 0.05, **p < 0.01, compared with control. C Representative TEM images of macrophages. The scale bar is 500 nm. Red arrows point to the location of the internalized AuNPs, and green arrows point to the injured mitochondria
