New Hybrid Nanostructures Detect Nanoscale Magnetism

Researchers at Rensselaer Polytechnic Institute have created a new process for growing a single multi-walled carbon nanotube that is embedded with cobalt nanostructures. Using this new hybrid material, the team determined that the electrical conductance of MWCNTs is sensitive enough to detect and be affected by trace amounts of magnetic activity. It is believed to be the first instance of demonstrating the detection of magnetic fields of such small magnets using an individual carbon nanotube.
