Metallic biomaterials

Due to its rising accumulation in the food chain and ongoing presence in ecosystems, metal contamination has piqued the curiosity of experts from all over the world. Environmentally hazardous heavy metal removal is being pursued utilizing a variety of techniques, such as ion exchange and precipitation, as well as chemical oxidation or reduction, electrochemistry, and filtration.

We produced and characterized copper(II)-chitosan complexes fabricated via in-situ precipitation as antibioticfree antibacterial biomaterials. Copper was bound to chitosan from a dilute acetic acid solution of chitosan and copper(II) chloride exploiting the ability of the polysaccharide to chelate metal ions.

The fiber composite was found to have excellent biocompatibility with significant cell growth, while the MTX-loaded PVA/HAP/FA composite showed cytotoxicity against A459 cells. The prepared fibrous composites will serve as a superior biomaterial for osteosarcoma-diseased bone repair after evidencing of in-vivo and clinical trials.

Highly porous Ti matrix composites can be a solution for some of the major clinical concerns for the load bearing implants such as low tribocorrosion resistance, stress shielding, and lack of biological anchorage. In order to respond to these needs, highly porous Ti-TiB-TiNx in-situ composites were synthesized by pressureless sintering using BN as reactant and urea as space holder. Corrosion behaviour was investigated at body temperature, in phosphate buffer saline solution (PBS), by measuring open circuit potential (OCP) and cyclic polarization.

The task of providing a reliable replacement for anatomic loss falls short of the original biology in both elegance and durability. Although prosthetic replacements are poor substitutes for healthy biology, disease and destruc- tion leave clinicians few alternatives. Teeth and their prosthetic replacement typify this dilemma. The healthy tooth is a thing to be admired – strong, compliant, chemically resistant, and even beautiful.

Since their first introduction, metallic biomaterials have always been designed to be corrosion resistant. For decades, this paradigm has become the mainframe of the biomaterials world. It has been cited in thousands of scientific papers and taught in hundreds of courses of materials for biomedical devices. It has also been followed by industries in developing millions of medical devices until today. Nowadays, with the advent of tissue engineering, biomaterials are envisaged to actively interact with the body.

Metals are used as biomaterials due to their excellent electrical and thermal conductivity and mechanical properties. Since some electrons are independent in metals, they can quickly transfer an electric charge and thermal energy. The mobile free electrons act as the binding force to hold the positive metal ions together. This attraction is strong, as evidenced by the closely packed atomic arrangement resulting in high specific gravity and high melting points of most metals.
