This month was a final step in dissertation writing. Described results might be fundamental for modern type of tissue analog preparation.Migration channels in form of straight lines obtained in ablation process provided the control of smooth muscle cells migration and spreading, mimicking their organization in blood vessel‘s wall. Poly-L-lysine/hyaluronic acid (PLL/HA) coatings cross-linked by carbodiimide or modified by silicon carbide nanoparticles introduction could be the most promising for surface functionalization of cardiovascular devices. Biomimetic multiscale surface functionalization of polyurethane/vinyl polychloride base materials improved their bio(hemo)compatibility. Presented results confirmed that significant improvement of blood contacting materials could be possible by fabrication of the multilayer structure mimicking the natural blood vessel‘s wall. The dissertation presented also a new approach in biomaterials hemocompatibility evaluation which seemed to be promising and would be developed in further experimental work.

My dissertation was sent to the reviewers. There is no more chance to improve the manuscript.
I'm waiting for their comments.

In this month I investigated formation of silver nanoparticles using metal island film technique. Four layers having thicknesses of 7, 10, 15 and 20 nm were sputtered at a rate of 2 A / s on polished Si wafers. . The deposited layer thickness was read on a quartz microbalance. The resulting silver layer was then subjected to annealing on the stage heating at 250 ° C under argon for 0.5 hours. The formated islands were analyzed using SEM and AFM. Average size obtained from 7 and 10 nm layers was 60 and 105 nm. For thicker layers islands lost thier oval shape and became irregular. Surface coverage was 46, 30, 29 and 33.8 %, respectively for increasing initial layer thickness.
The obtained structere can be applied to the Si cell as a plasmonic back reflector.
