The aim of the study was to fabricate titanium (Ti) material coated with functionalized carbon nanotubes (f-CNTs) that would have potential medical application in orthopaedics as an implantable electronic device. The novel biomedical material (Ti-CNTs-H2O) would possess specific set of properties, such as: electrical conductivity, non-toxicity, and ability(More)
Initial protein adsorption to the material surface is crucial for osteoblast adhesion, survival, and rapid proliferation resulting in intensive new bone formation. The aim of this study was to demonstrate that modification of a chitosan matrix of chitosan/hydroxyapatite (chit/HA) biomaterial for bone tissue engineering applications with linear β-1,3-glucan(More)
S OF PROFFERED PAPERS 767 was measured and compared with those of the non-irradiated control. Charge activity was tested by formation of 14C-Val-tRNA. It was found that 400 R did not cause significant mortality. However, 500 and 700 R resulted a mortality of 20 and 35% respectively. The charge activity of tRNAVal decreased, depending on the doses delivered.(More)
Coating the material with a layer of carbon nanotubes (CNTs) has been a subject of particular interest for the development of new biomaterials. Such coatings, made of properly selected CNTs, may constitute an implantable electronic device that facilitates tissue regeneration both by specific surface properties and an ability to electrically stimulate the(More)
The aim of this study was to determine which procedure for β-1,3-glucan gelation - newly developed dialysis against calcium salt or described in the literature thermal technique - is more appropriate for fabrication of a biomaterial designed for bone tissue engineering applications. Thus, β-1,3-glucan/hydroxyapatite scaffolds were prepared based on two(More)
Recent researches suggest participation of minerals in the formation of life under primordial conditions. Among all of the minerals, quartz seems to be one of the most probable to take part in such processes. However, an external source of energy is needed, e.g. electric discharge. A device simulating the proposed conditions was designed and was used to(More)
