Carbon-based implant materials are of interest because they are well accepted by the biological environment. Carbon fibrous materials developed in the Department of Special Ceramics of the University of Mining and Metallurgy in Cracow were tested in in vivo studies to determine their influence on the living body. For comparative purposes, different carbon(More)
Bone defect is one of the most frequent problems in bone tissue reconstruction in which application of a biomaterial filling is necessary. It creates a still rising demand of biomaterials for bone surgery. Polymer-ceramic nanocomposites (e.g. based on chitosan matrix) is a group of novel materials whose properties such as strength, Young's modulus,(More)
PURPOSE Preventing the formation of blood clots on the surface of biomaterials and investigation of the reasons of their formation are the leading topics of the research and development of biomaterials for implants placed into the bloodstream. Biocompatibility and stability of a material in body fluids and direct effect on blood cell counts components are(More)
Carbon nanotubes are expected to be of use in both genetic engineering and biomaterials engineering. In each of these potential areas of application, nanoparticles are introduced into a living organism either in the form of active biomolecule carriers or as a result of the degradation process of an implant. In the present study we focus on the in vivo(More)
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)
In the present study we focused on the in vitro and in vivo evaluation of two types of carbon fibres (CFs): hydroxyapatite modified carbon fibres and porous carbon fibres. Porous CFs used as scaffold for tissues regeneration could simultaneously serve as a support for drug delivery or biologically active agents which would stimulate the tissue growth; while(More)
The purpose of the study was to examine the response of macrophages and the concentration of selected released cytokines following contact with a new carbon-polylactide composite. The macrophages were grown on samples of the materials and on each of its components separately. Viability of the cells as well as concentrations of interleukins IL-6, IL-10,(More)
RATIONALE AND OBJECTIVES Thanks to the advanced studies in biomaterial engineering a panoply of polymers can be used to manufacture porous scaffolds for bone tissue regeneration. Suitability of the scaffold for its purpose is determined by factors like size of the pores, its orientation and shape, as well as biocompatibility of the material. Even though a(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)
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)
