Figure 11From: Optimized dispersion of nanoparticles for biological in vitro and in vivo studiesElectron microscopy of zinc oxide, silicon oxide and silver nanoparticles. Electron microscopic image at 100,000 times magnification (950 × 950 nm) from ZnO, SiOx and silver nanoparticle dispersions prepared in distilled water at a concentration of 0.02 mg/ml without stabilizer (PBS) or with addition of human serum albumin (+HSA) or mouse serum (+Serum) before giving concentrated PBS to the dispersion.Back to article page
