Fig. 6From: The Spatiotemporal Control of Osteoblast Cell Growth, Behavior, and Function Dictated by Nanostructured Stainless Steel Artificial MicroenvironmentsImmunofluorescent labeling of cell nucleus on different nanoporous artificial microenvironments. Cell nucleus was labeled blue with DAPI to analyze the number of viable cells after days 1 and 3. For both the days, the maximum number of viable cells were seen on 100-nm nanoporous surfaces. One hundred-nanometer nanopore diameter was marked as the transition step in the modulation of cell viability by the nanoporous surfacesBack to article page
