Nanotechnology: Detecting Lethal Diseases With Rust and Sand, Ho Chi Minh City Institute of Physics Study

ScienceDaily (Jan. 31, 2011) — The next big thing in medical diagnostics could be minutes particles of rust, iron oxide, coated with the material from which sand is formed, silicon dioxide. These magnetic nanoparticles, a mere 29 to 230 nanometers across, can be used to trap antibodies to the virus that causes cervical cancer and to the bacteria that causes potentially lethal diarrhea.
