The medical uses of silver include its use in wound dressings, creams, and as an antibiotic coating on medical devices. [ 2 ] [ 3 ] [ 4 ] Wound dressings containing silver sulfadiazine or silver nanomaterials may be used to treat external infections.
Metals have been used in treatments since ancient times. The Ebers Papyrus from 1500BC is the first written account of the use of metals for treatment and describes the use of Copper to reduce inflammation and the use of iron to treat anemia. Sodium vanadate has been used since the early 20th century to treat rheumatoid arthritis.
Metal ions and metallic compounds are often used in medical treatments and diagnoses. [18] Compounds containing metal ions can be used as medicine, such as lithium compounds and auranofin . [ 19 ] [ 20 ] Metal compounds and ions can also produce harmful effects on the body due to the toxicity of several types of metals. [ 18 ]
The human body has complex homeostatic mechanisms which attempt to ensure a constant supply of available copper, while eliminating excess copper whenever this occurs. However, like all essential elements and nutrients, too much or too little nutritional ingestion of copper can result in a corresponding condition of copper excess or deficiency ...
Subsequent research conducted at the University of Southampton (UK) compared the antimicrobial efficacies of copper and several non-copper proprietary coating products to kill MRSA. [35] [36] At 20 °C, the drop-off in MRSA organisms on copper alloy C11000 is dramatic and almost complete (more than 99.9% kill rate) within 75 minutes. However ...
Tungsten is one of the oldest metal ions to be incorporated in biological systems, preceding the Great Oxygenation Event. Before the abundance of oxygen in Earth's atmosphere, oceans teemed with sulfur and tungsten, while molybdenum, a metal that is highly similar chemically, was inaccessible in solid form. The abundance of tungsten and lack of ...
Aluminium oxide is used for its hardness and strength. Its naturally occurring form, corundum, is a 9 on the Mohs scale of mineral hardness (just below diamond). It is widely used as an abrasive, including as a much less expensive substitute for industrial diamond. Many types of sandpaper use aluminium oxide crystals.
Iron oxide nanoparticles may also be used in magnetic hyperthermia as a cancer treatment method. In this method, the ferrofluid which contains iron oxide is injected to the tumor and then heated up by an alternating high frequency magnetic field. The temperature distribution produced by this heat generation may help to destroy cancerous cells ...
