American researchers have managed to created the smallest magnetic nanoparticles in order to detect cancer cells, to attach themselves to them and to transmit important information through the representation of magnetic resonance.

Magnetic resonance has turned out to be of great aid to doctors in discovering tumors without surgery. The device uses magnetic waves which record different signals and then return in order to identify different tissues in the body, making the difference between bones and muscles, or fluids and solid matter.

Scientists have discovered that magnetic nanoparticles can be very useful in identifying cancer cells by using magnetic resonance. Just like smalls rockets, the nanoparticles seek cancer cells and attach themselves to them. Once attached, they act like a radio antenna, transmitting better information by magnetic resonance.

Science Daily has informed that the researcher Shouheng Sun and his colleagues from the Brown University in the USA have managed to create the smallest nanoparticles, and, because of the special coating that is used, the radio signal is even stronger. These nanoparticles are important because they help in differentiating the background, like water molecules in the body and a solid mass such as a tumor.
