Surface modification of polyurethanes with covalent immobilization of heparin AKSOY, AYŞEGÜL; Hasırcı, Vasıf Nejat; Hasırcı, Nesrin (2007-10-04) Thrombus formation and blood coagulation is a major problem associated with blood contacting products such as catheters, vascular grafts, arteries, artificial hearts and heart valves. An intense research is being conducted towards the synthesis of new hemocompatible materials and modifications of surfaces with biological molecules. In this study, polyurethane (PU) films were synthesized in medical purity from diisocyanate and polyol without using any other ingredients and their surfaces were modified by cov...

Surface Characterization and Biocompatibility of Selenium-Doped Hydroxyapatite Coating on Titanium Alloy Yilmaz, Bengi; Evis, Zafer; Tezcaner, Ayşen; Banerjee, Sreeparna (2016-11-01) Selenium-doped hydroxyapatite (HA) was biomimetically coated on Ti6Al4V plates with the aim of combining the anticancer and antibacterial properties of selenium with the biocompatibility and bioactivity of HA. For the coating process, the composition of 1.5 x SBF (solution with ion concentrations at 1.5 times that of simulated body fluid, SBF) was modified to include 0.15 mM selenate (SeO42-) ion. The selenium-doped HA coating was characterized by several methods, such as scanning electron microscopy, X-ray...

Surface Modification and Characterization of Multi-Walled Carbon Nanotube Kanbur, Yasin; Kucukyavuz, Zuhal (Informa UK Limited, 2011-01-01) Multi-walled carbon nanotubes (MWCNTs) were chemically functionalized by using sulfuric acid and nitric acid. The functionalization was done with two different acid ratio. The functionalized nanotubes were characterized with Fourier Transform Infrared Spectroscopy, X-Ray Photon Spectroscopy, Thermal Gravimetric Analysis, Elemental Analysis, Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy. Sulfonation of carbon nanotubes (CN) increased the electrical conductivity of carbon nanotubes ...
