Electrochemical Corrosion Resistance and In Vivo Bioactivity of Nickel, Silver and Cobalt Nanoparticles Materials for Medical Applications

This study experimentally investigated the influence of Nickle, Silver and Cobalt nanoparticles materials electrochemically and biologically for medical applications. In vitro, electrochemical corrosion resistance has been used to analysing the behaviour of the nanoparticles materials selected by simulation body fluid (SBF) as corrosive media at 37 °C. In vitro, the biological tableted method at 37 °C for 24 hr has been applied on laboratory white mouse skins to evaluate the effect of nanoparticles diluted solutions with normal saline on the growth of Candida-Albicans. The results showed that the nanoparticles materials used have a low tendency to corrosion electrochemically, and the Cobalt nanoparticles material has better corrosion resistance than that of Silver and Nickel in the same conditions. Furthermore, the growth of the C-Albicans decreased in the presence of nanoparticles material compared with another one, which gives the possibility to use the nanoparticles as a fungal antagonist.
