Physical characteristics of the growth substrate including nano- and microstructure play crucial role in determining the behaviour of the cells in a given biological context. To test the effect of varying the supporting surface structure on cell growth we applied a novel sol-gel phase separation-based method to prepare micro- and nanopatterned surfaces with(More)
In current paper we demonstrate the applicability of high viscous oligomeric alkoxide concentrates in fabrication of technologically interesting structures like nanometer diameter fibers (down to 200 nm), nanoneedles (tip radii 15-25 nm) and some micrometers wide linear surface structures. The approach is cost-effective and simple as it utilizes low-cost(More)
The invention of electrospinning has solved the problem of producing micro- and nanoscaled metal oxide fibres in bulk quantities. However, until now no methods have been available for preparing a single nanofibre of a metal oxide. In this work, the direct drawing method was successfully applied to produce metal oxide (SnO2, TiO2, ZrO2, HfO2 and CeO2) fibres(More)
