Characterization of denture acrylic resin surfaces modified by glow discharges
(Sage Publications, Inc., 1997)Resin samples prepared by compression molding using a poly (methyl methacrylate) (PMMA) denture base material were exposed to radio-frequency (rf) glow discharges to improve the wettability of the material. Fourier transform ... -
Growth of vertically aligned carbon nanotubes over self-ordered nano-porous alumina films and their surface properties
(Elsevier, 2012)Nanoporous anodic aluminum oxide (AAO) with self-organized arrays of uniform nanopores have been used for various applications in the fields of sensing, storage, separation and template-based fabrication of metal nanowires, ... -
Impedimetric detection and lumped element modelling of a hemagglutination assay in microdroplets
(Royal Society of Chemistry, 2016)Droplet-based microfluidic systems offer tremendous benefits for high throughput biochemical assays. Despite the wide use of electrical detection for microfluidic systems, application of impedimetric sensing for droplet ... -
In vitro biocompatibility of plasma-aided surface-modified 316L stainless steel for intracoronary stents
(Institute of Physics Publishing, 2010)316L-type stainless steel is a raw material mostly used for manufacturing metallic coronary stents. The purpose of this study was to examine the chemical, wettability, cytotoxic and haemocompatibility properties of 316L ... -
Oxygen plasma modification of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) film surfaces for tissue engineering purposes
(John Wiley & Sons, Inc., 2003)Plasma glow-discharge application is known as a technique to coat or modify the surfaces of various materials. In this study, the influence of oxygen rf-plasma treatment on surface and bulk properties of a biological ... -
Poly (hydroxyethyl methacrylate-glycidyl methacrylate) films modified with different functional groups: In vitro interactions with platelets and rat stem cells
(Elsevier, 2013)Copolymerization of 2-hydroxyethylmethacrylate (HEMA) with glycidylmethacrylate (GMA) in the presence of α-α′- azoisobisbutyronitrile (AIBN) resulted in the formation of hydrogel films carrying reactive epoxy groups. ... -
Preparation and characterization of poly(hydroxyethyl methacrylate-co-poly(ethyleneglycol-methacrylate)/hydroxypropyl-chitosan) hydrogel films: Adhesion of rat mesenchymal stem cells
(Hangug Gobunja Haghoi, 2010-12-02)This study examined the effects of the surface properties of the materials, such as the hydroxyl, methyl and amino groups, on rat bone marrow derived Mesenchymal Stem Cell (MSC) seeding. A series of hydrogels were prepared ... -
Rapid and alternative fabrication method for microfluidic paper based analytical devices
(Elsevier B.V., 2016)A major application of microfluidic paper-based analytical devices (µPADs) includes the field of point-of-care (POC) diagnostics. It is important for POC diagnostics to possess properties such as ease-of-use and low cost. ... -
Selective adsorption of L1210 leukemia cells/human leukocytes on micropatterned surfaces prepared from polystyrene/polypropylene-polyethylene blends
(Elsevier, 2014)The objective of this study is to prepare polymeric surfaces which will adsorb L1210 leukemia cells selectively more than that of healthy human leukocytes in order to develop new treatment options for people with leukemia. ... -
Surface-modified bacterial nanofibrillar PHB scaffolds for bladder tissue repair
(Taylor and Francis Ltd., 2016)The aim of the study is in vitro investigation of the feasibility of surface-modified bacterial nanofibrous poly [(R)-3-hydroxybutyrate] (PHB) graft for bladder reconstruction. In this study, the surface of electrospun ... -
XPS and water contact angle measurements on aged and corona-treated PP
(John Wiley & Sons, Inc., 1999)Effects of corona treatment and aging on commercially produced corona discharged polypropylene (PP) films were followed via surface sensitive roughness analysis by atomic force microscopy (AFM), water contact angle (WCA), ...
