Figure 7From: Quantitative analysis of nanoparticle internalization in mammalian cells by high resolution X-ray microscopyTransmission X-ray microimages of a 2D cultured HeLa cell. A) Co-cultured with500 μM naked AuNPs for 48h show the aggregation of AuNP clusters around the cell nucleus (Additional file 1). B) With NAB-Ni staining, AuNP clusters are imaged within the cell skeletons. Bars: 5 μm.Back to article page
