Influence of Electrospinning Conditions on the Structure and Properties of One - and Two-Component Polymer Nanofibers for Use in Tissue Engineering
Abstract:
The process of electrospinning is one of the most commonly used methods for the preparation of nano-scale and sub-micron fibers for use in tissue engineering. The observed increase in the interest stems from wide range of applications of this process, which gives the possibility of forming fibers from different types of polymers used in medicine as well as in other fields of nanotechnology and industry. The work carried out within the framework of the doctoral dissertation research focused on determining the impact of utilitarian - electrospinning parameters on morphology, molecular structure and molded fiber overmolecular level . An equally important task was the purpose of application - to determine the effect of morphology and properties of molded fiber on the behavior of cells seeded on them . The fibers formed from a synthetic polymer as well as with the addition of gelatin and collagen for comparison . Cytotoxicity evaluated nonwovens and molded in cell proliferation in- vitro studies .

Bioactive Nanocomposite Ceramic- Polymer Materials for Bone Tissue Regeneration
Abstract:
Based on the knowledge of bone tissue and the characteristics that should be present biofunctional material for the treatment of bone defects, a method of preparation of nanocomposite porous polymer- ceramic materials. Reinforcing phase and a candidate bioactive properties was nanohydroksyapatyt, as a matrix we choose biodegradable polymers from the group of aliphatic polyesters : polylactide and polycaprolactone .
To obtain a predetermined porosity materials used NaCl crystals with dimensions of 300 microns and 200 microns. Made strength tests allowed to assess the effect of the addition of nanoparticles on mechanical parameters . Microstructure analysis microscopy ( SEM ) and the study of the elemental composition by EDS was performed both before and after the additional saturation nanohydroksyapatytem electrophoretic ( EPD ) and incubated in SBF. The study allowed us to assess the bioactivity of the material received.

Asbestos: from Health Hazard to Nanotechnology Applications
Abstract:
Asbestos is a set of silicate minerals belonging to the amphibole and serpentine family. The three most common types of asbestos are chrysotile, amosite and crocidolite. Chrysotile is the most abundant mineral in asbestos manufactured. It affects strongly the biological-mineral system interactions, which have been widely investigated in order to single out the causes of health hazard associated with asbestos fibers. Chrysotile is actually more known for its deleterious environmental effects than for its unusual structure and morphology. It is possible to obtain synthetic geomimetic chrysotile without any health hazard effects. The synthesis of geomimetic chrysotile nanotubes is entirely based on a hydrothermal reaction system. Synthetic chrysotile nanotubes have a high potentiality for nanotechnological applications. With the aim at preparing the first synthetic geoinspired inorganic nanowires, we have started to synthesize metal nanoparticles like Ag, Cu, Au, capped with thiol. Stoichiometric synthetic chrysotile nanotubes have been partially filled with previously synthesized bimetallic nanoparticles by capillarity effect at room temperature and pressure using a suitable organic solvent. Furthermore, the charged surfaces of the synthetic chrysotile nanotubes can be exploited for assembling chromophores. Indeed, preliminary experiments have shown the ability of such nano-objects to template the growth aggregates of the anionic tetrakis (4-sulfonatophenyl) porphyrin. Chrysotile nanotubes can be used to make nanocomposites. Particularly interesting are conductive polymer composites. Submicrometric fibers of conductive polymer blend (polyniline-polyethylene oxide) filled with stoichiometric synthetic chrysotile nanotubes can be obtained by electrospinning. The presence of nanotubes into the electrospun fibers improved electrical properties. The parallel distribution of the nanotubes produced rigid and straight fibers with efficient electric transport properties. Such hybrid materials are interesting for perspectives in technological fields.

10th February 2014 (Monday) we had an opportunity to listen M.Sc Olga Urbanek lecture entitled:
The Effect of Hydroxyapatite Nanoparticles Addition on Selected Properties of Bioresorbable Nanocomposites After Gamma Sterilization Treatment
Abstract:
Sterilization is necessary process for biomateriasl prior to introduction into the human body in order to remove from the surface of pathogens , which are a potential source of infection, leading to rejection of the implant. It is important here that the sterilization did not cause changes in the properties of the material, thereby disqualifying it for medical use. In order to improve the resistance to gamma radiation sterilization of two commonly used in medicine polymers: poly (L- lactide ) and poly (lactide -co- glycolide ) nano - doped hydroxyapatite them ( nano - HA) . Samples of the starting material and nano - ceramics doped (1%, 5 % and 10% by weight . Nano -HA ) were performed in the form of films by casting from the solution. The increase in the dispersion of ceramic was obtained by ultrasonic . Radiation sterilization was performed with a standard for medical supplies dose of 25 kGy. Research methods GPC , DSC , TGA , FTIR , density , surface roughness , contact angle and the tensile strength showed that after sterilization by gamma radiation can be divided into a period of intense changes in the properties resulting from changes in the microstructure and properties of the stabilization period. The influence of nano -HA and gamma radiation the degree of crystallinity.

Advanced Techniques For The High Resolution X-ray Tomography As A New Tool For The Study And Evaluation Of Tissue Engineered products
Abstract:
In recent years, computed tomography (CT) has become a widely used technique for research in materials science and medicine, including basic research. Methods of micro-and nanoCT have great potential for characterization of tissue engineered products. By means of the computed tomography can accurately characterize the newly developed biomaterial tissue growth in the three-dimensional scaffold, the biomaterial and the degradation of the mechanical properties in situ. In this paper we will present the results of tissue-engineered products using the most advanced techniques for the High Resolution X-ray tomography.
