Stunning Research Shows High Potential for DNA Damage from Nanoparticles (Study)

'Nanoparticles are already used in the manufacture of sunscreens, cosmetics, sporting goods and other consumer products. Researchers are also investigating their use as drug-delivery mechanisms.'

Nanoparticle Applications
A survey of nanoparticle applications under development:

Nanoparticles are particles that have one dimension that is 100 nanometers or less in size.The properties of many conventional materials change when formed from nanoparticles. This is typically because nanoparticles have a greater surface area per weight than larger particles; this causes them to be more reactive to certain other molecules.

Nanoparticles are used, or being evaluated for use, in many fields. The list below introduces many of the uses under development. You can use the links in each paragraph to go to a detailed explanation.

Iron oxide nanoparticles can used to improve MRI images of cancer tumors. The nanoparticle is coated with a peptide that binds to a cancer tumor, once the nanoparticles are attached to the tumor the magnetic property of the iron oxide enhances the images from the Magnetic Resonance Imagining scan.
