SCIENTISTS have set a new Guinness World Record by creating the smallest medical robot - a device measuring just 120 nanometres that could assist in future cancer and Alzheimer’s treatments. The series of nanorobots was created by Soutik Betal during his doctoral research at University of Texas at San Antonio (UTSA) in the US could one day lead to huge medical advancements.

“We have developed nanocomposite particles that can be remotely controlled by an electromagnetic field. They function like extremely tiny robots that interact with biological cells,” said Ruyan Guo, a professor at UTSA. The nanocomposites are made of two different types of multifunctional oxide materials in a “core and shell” configuration.

The core is magnetic and changes ‘shape’ in response to magnetic fields. The ferroelectric shell is converts pressure into electric potentials. The magneto-elasto-electric coupled effect in the nanocomposites act as arms and legs that move the nanoparticle around to interact with targeted biological cells.
