World’s smallest medical robot hits Guinness Book of World Records

Prime News, International, (Texas), August 29:-A doctoral research student at the University of Texas has built the world’s smallest robot-medical robot- that cannot be seen with the human eye.

Creation of Soutik Betal, the robot measures 120 nanometer and has entered the Guinness Book of World Records for its negligible size, Fast Company reports.

The robot is basically a series of nanocomposite particles of multifunctional oxide materials that can be remotely controlled by an electromagnetic field.

The nanocomposites are made of two different types of multifunctional oxide materials in a “core and shell” configuration. The core is magnetic. It changes ‘shape’ in response to magnetic fields. The shell is ferroelectric. It 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. The nanorobots can move cells to align with one another, push cells into different locations and possibly be used to deliver medication into a cell.

Because the tiny robot is capable of interacting with biological cells, future applications could include direct medication to cells in conditions such as cancer and Alzheimer’s.
