Another month has passed...In May I focused on analysis of results which I obtained from micromechanical tests and FTIR studies. I’ve also summarized the thermal stability experiments. Calorimetric measurements and microscopic analysis of endothelial cell growth kinetics showed that polyelectrolyte multilayer films are stable in a broad range of temperatures. All results obtained so far were used to prepare a poster for the E-MRS 2012 Spring Meeting conference, for symposium focused on functional biomaterials.
