Blood-contacting devices have emerged in the 21st century as go-to clinical treatment for severe cardiovascular diseases. Due to their poor hemocompatibility, many coatings been developed improve biocompatibility with limited success due lack of robustness biomolecule conjugation. In this paper, we propose a new self-protonating, plasma polymerized, superimposed multi-layered nanoreservoir coat...

The present research attempt consists in the development of mesoporous hydroxyapatite using inexpensive ingredients using cetyltrimethylammonium bromide (CTAB) as template through a chemical-based hydrothermal method. Wide angle X-ray diffraction (XRD) reveals the formation of pure single-phased hydroxyapatite particles. Fourier transform infrared absorption spectroscopy (FTIR) and electron dif...

Pure iron has been considered as a promising candidate for biodegradable implant applications. However, a faster degradation rate of pure iron is needed to meet the clinical requirement. In this work, metal vapor vacuum arc technology was adopted to implant zinc ions into the surface of pure iron. Results showed that the implantation depth of zinc ions was about 60 nm. The degradation rate of p...

Present prosthetic heart valves, while hemodynamically effective, remain limited by progressive structural deterioration of tissue valves or the burden of chronic anticoagulation for mechanical valves. An idealized valve prosthesis would eliminate these limitations. Polymeric heart valves (PHVs), fabricated from advanced polymeric materials, offer the potential of durability and hemocompatibili...

Respiratory insufficiency is a major cause of neonatal mortality and long-term morbidity, especially in very low birth weight infants. Today, non-invasive and mechanical ventilation are commonly accepted procedures to provide respiratory support to newborns, but they can reach their limit of efficacy. To overcome this technological plateau and further reduce mortality rates, the technology of a...
