Topography and wettability of nanopatterned PMMA and PS surfaces embossed with various anodized aluminum oxide nanotemplates

The interactions between biological cells and nanometer-scale structured surfaces are very important issues in nanobiotechnology. Most current methods of fabricating such surfaces are costly and are not suitable for the production of a nanometer-scale structured surface that will be used merely as a disposable tool in cell biological studies. We developed and optimized an embossing method of polymers with nanoporous AAOs which is easy, cheap and fast in fabricating nanometer-scale structures on the surface of polymers. We think this method can be applied not only in cellular nanobiotechnogy but also in other areas of nanotechnogy.
