Metals in medicine are used in organic systems for diagnostic and treatment purposes. [1] Inorganic elements are also essential for organic life as cofactors in enzymes called metalloproteins . When metals are under or over-abundant in the body, equilibrium must be returned to its natural state via interventional and natural methods.
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 ...
In biology and medicine, nitric oxide is however an important signalling molecule in nature and this fact is the basis of the most important applications of metal nitrosyls. The nitroprusside anion, [Fe(CN) 5 NO] 2− , a mixed nitrosyl cyano complex, has pharmaceutical applications as a slow release agent for NO.
Lithium oxide – Li 2 O; Magnesium oxide – MgO; Potassium oxide – K 2 O; Rubidium oxide – Rb 2 O; Sodium oxide – Na 2 O; Strontium oxide – SrO; Tellurium dioxide – TeO 2; Uranium(IV) oxide – UO 2 (only simple oxides, oxyhalides, and related compounds, not hydroxides, carbonates, acids, or other compounds listed elsewhere)
For example, arsenopyrite, a common impurity in gold- and copper-containing ores, liberates arsenic trioxide upon heating in air. The processing of such minerals has led to numerous cases of poisonings, [ 22 ] and after the mine is closed, the leftover trioxide waste will present environmental hazard (as was the case with the Giant Mine , for ...
The metal ion in this reaction can be reduced, oxidized, and then re-reduced, in a process called redox cycling that can generate reactive oxygen species. [ citation needed ] The relative importance of the antioxidant and pro-oxidant activities of antioxidant vitamins is an area of current research, but vitamin C, for example, appears to have a ...

For example, styrene-butadiene block copolymers have a central polybutadiene chain with polystyrene end caps. When treated with OsO 4, the butadiene matrix reacts preferentially and so absorbs the oxide. The presence of a heavy metal is sufficient to block the electron beam, so the polystyrene domains are seen clearly in thin films in TEM.
