Researchers from the National Polytechnic Institute (IPN) developed a nanostructured coating that aims to prevent the patient from returning to the operating room due to the wear of the device, thanks to the possibility of reducing friction and loosening to extend the life cycle of prostheses for biomedical use.
Luis Héctor Hernández, a scientist at the School of Mechanical and Electrical Engineering (ESIME), Zacatenco Unit, explained that the purpose is to reduce wear at points where there is greater movement between bone structures and stimulate the development of bone cells (osteoblasts) in titanium oxide coatings with gold and platinum nanoparticles.
Similarly, another of the objectives of this nanorecution was to improve the personalized hip prosthesis that was created at ESIME more than two years ago, since it will improve the structural integrity of the bone-prosthesis system.
The researcher explained that to improve biocompatibility, the titanium oxide coating on the metal surface where the bone and prosthesis act must be increased. "This development has a corrosion resistance 10 times greater than a simple titanium base used in commercial prostheses. The mineral hydroxyapatite was also synthesized by the hydrothermal method and electrodeposited on a transparent area of conductive glass that improves its operation," he said.
Carlos Torres Torres and Dayvis Fernández Valdés, from ESIME Zacatenco, as well as Martín Daniel Trejo Valdez, from the School of Chemical Engineering and Extractive Industries (ESIQIE), collaborated in the project.
