Bioactive metals
WebAug 4, 2024 · Medical devices made of bioactive glasses and metals that dissolve at the end of their operational lifespan could replace other types of implants and eliminate the need for invasive removal once they have served their purpose, say researchers at Missouri University of Science and Technology. Biometals are metals normally present, in small but important and measurable amounts, in biology, biochemistry, and medicine. The metals copper, zinc, iron, and manganese are examples of metals that are essential for the normal functioning of most plants and the bodies of most animals, such as the human body. A few (calcium, potassium, sodium) are present in relatively larger amo…
