Abstract

 

The main aim of this research activity is to investigate the adhesion and bioactivity of different cell types on biomimetically modified 3-dimensional substrates, such as Si and different types of polymers, in order to develop scaffolds for potential use in tissue engineering applications. To this end, we use ultrafast laser structured Si wafers, comprising dual scale roughness in the micro- and nano- length scales. In this respect, the behaviour of fibroblast and neurons cultured on substrates prepared to exhibit gradient morphologies and/or chemistries was investigated. We have shown that it is possible to preferentially tune cell adhesion and growth, through choosing proper combinations of topography and chemistry of 3D micro/nano structures.
