Nanostructure-Enabled and Macromolecule-Grafted Surfaces for Biomedical Applications

PVA and EDTA grafted superparamagnetic Ni doped iron oxide nanoparticles prepared by constant current electrodeposition for biomedical applications

In this paper, a rapid and room temperature electrochemical method is introduced in preparationof Ni doped iron oxide nanoparticles (Ni-IONs) grafted with ethylenediaminetetraacetic acid (EDTA)and polyvinyl alcohol (PVA). EDTA/Ni-IONs and PVA/Ni-IONs samples were prepared through baseelectro-generation on the cathode surface from aqueous solution of iron(II) chloride, iron(III...

Dextran grafted silicon substrates : preparation, characterization and biomedical applications

Biodevices used in the cardiovascular system suffer from well-known problems associated with surfaceinduced gas embolism and thrombosis. In order to improve the biocompatibility of these devices, biomimetic coatings show good promise. We recently synthesized a coating layer of dextran, a relatively simple and well characterized neutral polysaccharide, with the purpose of mimicking the cells' gl...
