Figure 6From: Synthetic osteogenic extracellular matrix formed by coated silicon dioxide nanospringsFESEM of Bone Matrix Deposition on Coated Silicon Dioxide Nanosprings. Hydroxyapatite crystals (red arrow) formation are seen along with filopodia (yellow arrow) from normal human osteoblasts (green arrow) on a mat of silicon dioxide nanosprings after 36 days incubation at 37°C and 5% CO. The coating on the nanosprings was titania, zinc oxide and gold nanoparticles.Back to article page
