An article published in the journal Scientific Reports says researchers from the Centre for Biomedical Technology at Universidad Politécnica de Madrid (CTB-UPM) have developed a new technology that will allow them to modify the surface of metallic biomaterials in order to improve their interaction with the human body.

The procedure, called Activated Vapor Silanization (AVS), consists of coating the material surface with a layer of less than one-thousandth of a millimeter and joining molecules that are naturally found in humans. When applied to materials used to manufacture prostheses, the process reduces implant rejection and, consequently, increases its useful life, the researchers say.

“The AVS technology is a versatile procedure that can be easily adapted to the procedures currently used to develop metallic biomaterials,” says José Pérez, one of the researchers involved in the study.
