Quaternized copolymers of 4-vinylpyridine and poly(ethylene glycol) methyl ether methacrylate are known to have antibacterial properties and have displayed biocompatibility in red blood cell hemolysis assays. The results from hemolysis assays have shown substantial promise, but the technique is rudimentary and only a first step toward the determination of biocompatibility. The present paper fur...

Herein, we report the effects of graphene oxides on human fibroblast cells and mice with the aim of investigating graphene oxides' biocompatibility. The graphene oxides were prepared by the modified Hummers method and characterized by high-resolution transmission electron microscope and atomic force microscopy. The human fibroblast cells were cultured with different doses of graphene oxides for...

Objective. The purpose of this review paper is to review the literature regarding the toxicology of mercury from dental amalgam and evaluate current statements on dental amalgam. Materials and Methods. Two key-words "dental amalgam" and "toxicity" were used to search publications on dental amalgam biocompatibility published in peer-reviewed journals written in English. Manual search was also co...

Exposure of blood to hemodialysis membranes results in numerous interactions between the blood elements and the membrane. Transformation and adsorption of plasma proteins (such as complement) and activation of blood cells (such as neutrophils and monocytes) have been studied most extensively by nephrologists in recent years. There is no consensus on the definition of biocompatibility for dialyz...

Cardiovascular disease is the dominant cause of mortality in developed countries, with coronary artery disease (CAD) a predominant contributor. The development of stents to treat CAD was a significant innovation, facilitating effective percutaneous coronary revascularization. Coronary stents have evolved from bare metal compositions, to incorporate advances in pharmacological therapy in what ar...

Mechanical and biological biocompatibility is important consideration for materials that are used as metallic implants. During the past two decades, many β-type titanium alloys composed of non-toxic and hypoallergenic elements with low Young’s moduli have been developed worldwide. Recently, the development of new titanium-based materials to improve the mechanical and biological biocompatibility...

Amanda Williams, University of South Carolina, 2012 SURF Fellow Advisor: Prof. Hamid Garmestani Graduate Mentor: Parisa Pooyan Introduction Many biopolymers in place today lack native biomechanical characteristics of the target tissue and are mechanically and thermally unstable. A suggested material to combat these issues is a composite material made of a biopolymer matrix with a reinforcing ag...
