Splash!!! I wish it had been me that jumped into cold blue water…Ehh, instead that I had an additional work…my freshly prepared buffer was spilled on a lab floor...it’s quite difficult to focus on important things when outside is the middle of summer. Anyway, opportunity to work in the lab with an air condition had convinced me to continue my science adventure in July. It was good time for reading papers because was really quite everywhere in the Institute. Moreover I carried out studies on diffusion phenomenon within cross-linked and non cross-linked polyelectrolyte multilayer films. I prepared samples for strength tests and for SEM analysis. I’ve started studies of endothelial and smooth muscle cells growth kinetics on PLL/HA films.
