Another month has passed and the next papers have been read...This time I focused on the literature concerning methods of cellular adhesion and proliferation control on the polyelectrolyte multilayer surfaces. I produced several series of samples to evaluate the micro-hardness. I prepared specimens to impact R test, which will allow to assess the confluence and the stability of endothelial monolayer, as well as the risk of activation of the coagulation system by the proposed tissue analog. I also continued studies on growth and morphology of commercially available HUVEC cell line and fibroblast line (as a model cell line) on the previously functionalized polyelectrolyte surfaces with varying degree of cross-linking.
