Figure 1From: Quantitative analysis of nanoparticle internalization in mammalian cells by high resolution X-ray microscopyResults of the cell survival test. Cell survival test of EMT cells exposed to AuNPs with or without PEG capping. The cells were continuously co-cultured with colloidal nanoparticles for 24 h. The cell viability was measured by direct counting the cell number by trypan blue exclusion. The data are plotted as the percentage of surviving cells compared to untreated control specimens.Back to article page
