Surface characterization and cytocompatibility evaluation of silanized magnesium alloy AZ91 for biomedical applications.
Mg alloys with high Al contents have superior corrosion resistance in aqueous environments, but poor cytocompatibility compared to that of pure Mg. We have silanized the cast AZ91 alloy to improve its cytocompatibility using five different silanes: ethyltriethoxysilane (S1), 3-aminopropyltriethoxysilane (S2), 3-isocyanatopyltriethoxysilane (S3), phenyltriethoxysilane (S4) and octadecyltriethoxy...
متن کاملOxide Film and Porosity Defects in Magnesium Alloy Az91
Porosity is a major concern in the production of light metal parts. This work aims to identify some of the mechanisms of microporosity formation in magnesium alloy AZ91. Microstructure analysis was performed on several samples obtained from gravity-poured ingots in graphite plate molds. Temperature data during cooling was acquired with type K thermocouples at 60 Hz at three locations of each ca...
متن کاملComparison of Electrochemical Methods for the Evaluation of Cast AZ91 Magnesium Alloy
Linear polarization is a potentiodynamic method used for electrochemical characterization of materials. Obtained values of corrosion potential and corrosion current density offer information about material behavior in corrosion environments from the thermodynamic and kinetic points of view, respectively. The present study offers a comparison of applications of the linear polarization method (fr...
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...
