Fig. 1From: The Spatiotemporal Control of Osteoblast Cell Growth, Behavior, and Function Dictated by Nanostructured Stainless Steel Artificial MicroenvironmentsFabrication of nanoporous stainless steel artificial microenvironments. a Scanning electron microscopy of nanoporous surfaces on stainless steel substrates. Highly defined nanopore diameters between 100 and 220 nm were fabricated. Scale bar for flat = 500 nm, 100 = 300 nm, 180 = 500 nm, 200, and 220 = 1 μm. b Graphical representation depicting a linear relationship between anodization voltage and nanopore diameterBack to article page
