By a News Reporter-Staff News Editor at Health & Medicine Week -- Data detailed on Proteins have been presented. According to news reporting out of Shanghai, People's Republic of China, by NewsRx editors, research stated, "Understanding and controlling the process of electrochemical deposition (ECD) of a mineralized collagen coating on metallic orthopedic implants is important for engineering highly bioactive coatings. In this work, the influence of different ECD parameters was investigated."
Our news journalists obtained a quote from the research from the Chinese Academy of Science, "The results showed that the mineralization degree of the coatings increased with deposition time, voltage potential and H2O2 addition, while chitosan addition led to weakening of mineralization, heavy mineralization resulted in a porous coating morphology. Furthermore, two typical coatings, dense and porous, were analyzed to investigate their microstructure and evaluated for their cytocompatibility; the dense coating showed better osteoblast adhesion and proliferation. Based on our understanding of how the different coating parameters influenced the coating, we proposed an ECD process in which the pH gradient near the cathode and the collagen isoelectric point were suggested to play crucial roles in controlling the mineralization and morphology of the coatings."
According to the news editors, the research concluded: "The proposed ECD process may offer a guide for controlled deposition of a desired bioactive coating."
