Bioactive glasses (BGs) are widely studied for bone regeneration primarily because of their ability to bond to living bone, which is attributed to the formation of a hydroxyapatite layer on the glass surface in contact with the body fluids. BGs can be used as carriers for inorganic therapeutic ions. One of them is cobalt which is able to target the cellular hypoxia inducible factor 1α (HIF-1α)...

Biomedical coatings exhibiting antibacterial properties are receiving increasing attention to enhance the surface properties of metallic implants. The current study focuses on the fabrication and characterization of copper(II) – chitosan (Cu(II)-CS) – strontium doped bioactive glass (SrBG) composite coatings on stainless steel substrates via electrophoretic deposition (EPD). Initially,...

Due to its chemical similarity to bones and teeth the hydroxyapatite exhibits excellent biocompatibility1 with soft tissues such as skin, muscle and, gums, making it an ideal candidate for orthopedic and dental implants or components of implants, presenting as a high interest biomaterial scientific2-4. Due to its wide application as a biomaterial, it is necessary to develop materials with...

The work deals with the surface modification of silicon nitride by the heat treatment to make material bioactive. The silicon nitride was sintered with different sintering additives using FAST in order to form bioactive grain boundary phases. The heat treatment by oxy-acetylene flame was used to create bioactive porous surface layer of Si3N4. Various combinations of sintering additives were...
