• their influence on interactions with fibroblasts and platelets. Our results show that PTYR nanocoatings significantly reduced platelet adhesion and activation, whereas PDA coatings, due to their higher primary amine content, could in some cases enhance platelet adhesion. Furthermore, fibroblast

• attachment was primarily influenced by coating roughness, with a specific threshold beyond which adhesion did not increase or was negatively impacted. These findings highlight the potential of engineered PTYR nanocoatings for developing advanced hemocompatible surfaces for biomedical implants. Keywords

• case of LNM/C composites, the lithium intercalation is almost completely finished at 3.64 V, but for pure Li1.4Ni0.5Mn0.5O2+x it takes place over a wider potential range. It means that the carbon nanocoatings enable the polarization decrease upon lithium intercalation [23]. After galvanostatic cycling
