Researchers from the Far Eastern Federal University (FEFU) and Korea University (Republic of Korea) have developed devices to target cancer with precise drug delivery.
The devices, nanosprings, are made of cobalt and iron and have the properties of a magnet and are, as their name implies, springy. They can be used in nanorobots and nanosensors, Nanoscale research journal writes.
It is only recently that the ferromagnetic properties of nanosprings have become researched. They are very small in size which makes it extremely difficult to study them; they consist of ‘wires’ with a length of just about 200 atoms.
Assistant Professor at the Computing System Department at the FEFU School of Natural Sciences Alexander Samardak says that nanosprings can be guided using magnetic fields. According to the researcher, nanosprings have similar properties as macrosprings, so they can be widely used in nanotechnology. In addition, they can be useful in protein molecules express test systems.
Young experts at the FEFU School of Natural Sciences took part in the research.
