Nanoscale magnets made from graphene can be used in medical electronics

A scientific team from the University of Olomouc in the Czech Republic announced that they have used graphene to develop the world’s smallest metal magnet, which can be used in various fields such as nuclear magnetic resonance imaging, water treatment, biochemistry and electronics.

Researchers have successfully chemically modified graphene to capture ultra-tiny metal nanoparticles, according to reports. “This technique successfully avoids its reaction with oxygen to form the more common but weaker magnetic metal oxides,” says Zadek Zbozhir, an expert at the University of Olomouc. According to the report, graphene is a two-dimensional crystal made of carbon atoms with only one atomic thickness. It is stronger than steel, conducts electricity higher than copper, and can fully transmit light.

  

Chemically modifying it enables “control of its electrical, optical and magnetic properties,” Zborgil said in the research report. “This has helped us create a new class of magnets that are very powerful and stable in the atmosphere,” the study said. Zbozhir’s team made the mass production of this new nanomagnet possible. According to the report, scientists are currently conducting experiments on the application of this new nanomagnet in the field of medical diagnosis. In addition, the magnet is expected to be used in fields such as ecology, electronics and biotechnology.
