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 ...
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 ...
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.
While iron oxide used to make nanoparticles is biodegradable, the toxicity of magnetic nanoparticles is still under investigation. Some research has found no signs of damage to cells, while others claim that small (< 2 nm) nanoparticles can diffuse across cell membranes and disrupt organelles. [31] [32]
Magnetic-targeted carriers, also known as MTCs or magnetic vehicles, are micro- or nanoparticles that carry an anticancer drug to the target site by using an external magnetic field and field gradient to direct the desired drug. Usually, the complex involves microscopic beads of activated carbon, which bind the anticancer drug.
Drug-loaded dextran nanoparticles. Dextran has indirect applications in nanoparticles as a coating. Iron oxide nanoparticles coated with dextran can be loaded with the microRNA miR-29a to selectively target breast cancer cells and down-regulate anti-apoptotic genes leading to successful breast cancer treatment.
