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 ...
Fingerprint powders are commonly used because of the versatility associated with this technique. There is a large selection of fingerprint powder compositions that have evolved, over time, to enable the safe and effective use of fingerprint powders on a wide range of backgrounds. [3] [5] [6]
Research has shown that nanoscale iron particles can be effectively used to treat several forms of ground contamination, including grounds contaminated by polychlorinated biphenyls (PCBs), chlorinated organic solvents, and organochlorine pesticides. Nanoscale iron particle are easily transportable through ground water, allowing for in situ ...
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 ...
Many applications of engineered cerium oxide nanoparticles naturally disperse themselves into the environment, which increases the risk of exposure. There is ongoing exposure to new diesel emissions using fuel additives containing CeO 2 nanoparticles, and the environmental and public health impacts of this new technology are unknown. EPA's ...
The opportunity for functionalizing nanoparticles in such ways is especially beneficial when targeting areas of the body that have certain physiochemical properties that prevent the intended drug from reaching the targeted area alone; for example, some nanoparticles are able to bypass the Blood Brain Barrier to deliver therapeutic drugs to the ...
Divers uncovered a 3,000-year-old clay figurine in Italy's Lake Bolsena, revealing human fingerprints and shedding light on Iron Age rituals. Discover the story. ... Still, it could have offered ...
Ninhydrin is most commonly used to detect fingerprints in forensic cases, as the terminal amines of lysine residues in peptides and proteins sloughed off in fingerprints react with ninhydrin. [2] [3] Ninhydrin is a white solid that is soluble in ethanol and acetone. [1] Ninhydrin can be considered as the hydrate of indane-1,2,3-trione.
