Fabrication of pillar-like titania nanostructures on titanium and their interactions with human skeletal stem cells

Surface nanotopography is known to influence the interaction of human skeletal (mesenchymal) stem cells (hMSC) with a material surface. While most surface nanopatterning has been performed on polymer-based surfaces there is a need for techniques to produce well-defined topography features with tuneable sizes on relevant load-bearing implant materials such as titanium (Ti). In this study titania nanopillar structures with heights of either 15, 55...
