    The purpose of this study was to analyze surface chemical species deposited on various implant materials immersed in simulated body fluid (SBF). The investigated materials including pure titanium, two beta titanium alloys and stainless steel (316L) were formed into discs using cold pressing and sintering. The samples were examined using SEM and mid-IR microscopes. All the sample discs exhibited nucleation and growth of calcium phosphates, precipitated from the SBF solution containing calcium, phosphate and other ions. The results have shown that the nucleation and growth of phosphates depend on the alloy composition and become more intensive in the case of the titanium alloy with the niobium additio

    W pracy przedstawiono wyniki badań adsorpcji mucyny zwierzęcej na powierzchni wybranych biomateriałów. Przebadano po dwie próbki każdego z materiałów, których powierzchnie różniły się chropowatością. Badania przeprowadzono za pomocą mikrospektroskopii w podczerwieni z transformacją Fouriera (FT-IRM). Wyniki badań wskazują na adsorpcję mucyny do wszystkich testowanych materiałów. Zaobserwowano wpływ rodzaju biomateriału na intensywność adsorpcji testowanej proteiny do jego powierzchni.This work presents results of research of animal mucin adsorption on the surface of selected biomaterials. Two samples of each material with different surface roughness were investigated. The tests were performed using Fourier-transform infrared microspectroscopy (FT-IRM). The results indicate that mucin adsorb to all tested materials surface. The influence of biomaterial type on protein adsorption intensity to material surface was observed

    W pracy przedstawiono badania struktury chemicznej oraz morfologii nanokrystalicznych hydroksyapatytów: niedomieszkowanego oraz domieszkowanego jonami krzemianowymi SiO 4 4- . Próbki do badań uzyskano niekonwencjonalną techniką chemicznej kondensacji w fazie gazowej z wykorzystaniem niskociśnieniowego płomienia (CCVC). Do badań zastosowano mikroskopię elektronową TEM i SEM oraz metody spektroskopii NMR i IR w ciele stałym. Stwierdzono istotny wpływ jonów krzemianowych na strukturę chemiczną hydroksyapatytu.This paper reports a systematic investigation on Si-substituted and unsubstituted synthetic hydroxyapatites produced by the NanoSpray TM and combustion chemical vapor condensation (CCVC) process. The studies were focused on structural properties, crystal morphology and chemical composition of the samples. Various analytical methods, such as electron microscopy, high-resolution solid-state nuclear magnetic resonance (NMR) and infrared spectroscopy were used. A significant effect of silicate ions on the hydroxyapatite structure was found
