Coating Dependent In Vitro Biocompatibility of New Fe-Si Nanoparticles

In vitro biocompatibility of low and medium molecular weight chitosan–coated Fe3O4 nanoparticles

Objective(S): The chitosan - Fe3O4 core - shell nanoparticles were synthesized. The nanoparticles should be coated properly in the shape of core-shell, so that they remain hidden from the body's immune system after coating. Effects of different molecular weight in coating were investigated. Methods: Nanoparticles coated with low and ...

Biocompatibility of poly2methoxyethylacrylate coating for cardiopulmonary bypass.

The systemic inflammatory response to cardiopulmonary bypass (CPB) may contribute to the development of postoperative complications. Heparin-coated circuits and poly2methoxyethylacrylate (PMEA)-coated circuits have been developed to reduce the risk of such complications. We compared the biocompatibility of these circuits. Twelve patients scheduled to undergo elective coronary artery bypass graf...

Biocompatibility of Engineered Nanoparticles

Biocompatibility of crystalline opal nanoparticles

BACKGROUND Silica nanoparticles are being developed as a host of biomedical and biotechnological applications. For this reason, there are more studies about biocompatibility of silica with amorphous and crystalline structure. Except hydrated silica (opal), despite is presents directly and indirectly in humans. Two sizes of crystalline opal nanoparticles were investigated in this work under crit...

In Vitro Biocompatibility of Si Alloyed Multi-Principal Element Carbide Coatings

In the current study, we have examined the possibility to improve the biocompatibility of the (TiZrNbTaHf)C through replacement of either Ti or Ta by Si. The coatings were deposited on Si and 316L stainless steel substrates by magnetron sputtering in an Ar+CH4 mixed atmosphere and were examined for elemental composition, chemical bonds, surface topography, surface electrical charge and biocompa...
