Preparation and characterization of PEG/Dextran coated superparamagnetic Iron Oxide (Fe3O4) nanoparticles for biomedical applications
Recent progress in nanotechnology and electrochemical methods can be applied to fine control of the size, crystal structure, and surface properties of iron oxide nanoparticles. Here we appliedcathodic electrochemical deposition (CED) as an efficient and effective tactic for synthesisand double coating of surface of superparamagnetic iron oxide nanoparticles (SPIONs). In first step, bare Fe3O4 n...

متن کاملTribological Property of FG/UHMWPE Composites
Fluorinated graphene/ultra high molecular weight polyethylene (FG/UHMWPE) composites were prepared by ultrasonic dispersion and hot pressing. The mechanical propertys and tribological property of pure UHMWPE and FG/UHMWPE composites were investigated by micro hardness tester and high-speed reciprocating friction tester. The wear volume of the sample was measured by the scanning electron microsc...
متن کاملNanotribology of CoCr–UHMWPE TJR prosthesis using atomic force microscopy
Ultra high molecular weight polyethylene (UHMWPE) submicron wear debris particles in total joint replacement (TJR) prosthesis have been observed clinically to cause osteolysis. In this study, the formation of UHMWPE submicron wear debris was investigated by modeling a nanoscale asperity on the surface of a CoCr femoral component of a total knee replacement (TKR) prosthesis using a Si3N4 AFM com...
متن کاملBSA nanoparticles loaded with IONPs for biomedical applications: fabrication optimization, physicochemical characterization and biocompatibility evaluation
Objective(s): Cancer diagnosis in its early stages of progress, can enhance the efficiency of treatment utilizing conventional therapy methods. Non-biocompatibility of iron oxide nanoparticles (IONPs) has made a big challenge against their usage as a contrast agent. Efficient coverage by biomolecules such as albumin can be a solution to overcome this problem. Herein, albumin-coated IONPs were p...
