Bloody Spring has came… In the darkness of air conditioned lab I have started hemocompatibility assays. PEMs were prepared on PCV tubes in order to perform experiments in aortic flow simulator. I’ve also continued CLSM visualization of smooth muscle cells growing on samples modified by migration channels. Finally, coatings functionalized by the SiC or Ag nanoparticles for the ATR-FTIR analysis were prepared during this few sunny days.
