Nanoscale iron particles are sub-micrometer particles of iron metal. [1] Due to their high catalytic activity, low toxicity, and strong adsorption capacity, iron-based nanoparticles are widely utilized in drug delivery, magnetic targeting, gene therapy, and environmental remediation. [2]
Labelling cells (e.g. stem cells, dendritic cells) with iron oxide nanoparticles is an interesting new tool to monitor such labelled cells in real time by magnetic resonance tomography. [13] [14] Some forms of Iron oxide nanoparticle have been found to be toxic and cause transcriptional reprogramming. [15] [16]
Hiduminium or R.R. alloys (2% copper, iron, nickel): used in aircraft pistons Hydronalium (up to 12% magnesium, 1% manganese): used in shipbuilding, resists seawater corrosion Italma (3.5% magnesium, 0.3% manganese): formerly used to make coinage of the Italian lira
Ferrite nanoparticles or iron oxide nanoparticles (iron oxides in crystal structure of maghemite or magnetite) are the most explored magnetic nanoparticles up to date.Once the ferrite particles become smaller than 128 nm [22] they become superparamagnetic which prevents self agglomeration since they exhibit their magnetic behavior only when an external magnetic field is applied.

The aqueous solution of these complexes in different concentrations is taken in a quartz vessel and reduced using a photoreactor. Polyvinylpyrrolidone can be used as a stabilizer. The size and composition of the nanoparticles vary with the concentration of the aqueous solution. The composition of the nanoparticles can be analyzed using EDX studies.
Platinum nanoparticles become more chemically stable when alloyed with iron, cobalt, or nickel. The platinum alloys also have a better detection range and catalytic activity than platinum alone. [citation needed] These magnetic metal additions to platinum reduce the overall sensitivity to oxidation while maintaining the desirable magnetic ...
The alloy absorbs the oxygen vapor and saturates, facilitating a chemical reaction between zinc and oxygen. The nanostructure develops as the ZnO solidifies and grows outwards from the gold seed. This reaction can be highly controlled to produce more complex nanostructures by modifying the size and arrangement of gold seeds, and of the alloys ...
