Figure 1From: Iron oxide nanoparticles induce human microvascular endothelial cell permeability through reactive oxygen species production and microtubule remodeling Size distribution and cell uptake of iron nanoparticles. A, TEM micrograph of iron nanoparticles in 0.1% FBS cell culture media at the concentration of 50 μg/ml. B, Dynamic light scattering measurements of iron nanoparticles in 0.1% FBS cell culture media at the concentration of 50 μg/ml. C, TEM micrograph of iron nanoparticle uptake by HMVECs. HMVECs were stimulated with 50 μg/ml iron nanoparticles for different periods of time ranging from 10 minutes to 5 hours as indicated. The arrows indicate the location of iron nanoparticles. Each TEM micrograph represents one HMVEC.Back to article page
