The speed at which light travel we are shirking the size of computer at twice of that speed. Nanotechnology is a result of this process. Richard Feynman was the start of the nanotechnology, but in this week Soutik Betal has taken this industry to a text level.
Under the guidance of professors Ruyan Guo and Amar S. Bhalla from University of Texas, Soutik Betal has built the world’s smallest medical robot. The device was created by Soutik Betal during his Electrical Engineering doctoral program. Researcher said technology like this will be the future of direct medication to cells in diseases like cancer and Alzheimer’s.
This robot has entered the Guinness Book of World Records for its negligible size. The size of this world’s smallest medical robot is too small that even a human eye can’t see it. It doesn’t look anything like C-3PO or R2-D2, or even BB-8. The size of this robot is insanely 120 nanometer, which gives it a fair advantage over anything else.
“In a nutshell, 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.
This world’s smallest medical robot is technically a series of nanocomposite particles of two different types of multifunctional oxide materials in a core and shell configuration that can be remotely controlled by an electromagnetic field. The core is magnetic and changes the shape in response to magnetic fields.
According to Guo, the detachable nanoparticles could lead to medical advancements in the future.
The ferroelectric shell 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 help it to move cells in a coordination with one another.
The fabrication of core-shell structured materials have been developed through international research exchanges with collaborators in Brazil, the team discovered and Betal demonstrated the nanocomposites produced permeable motion.
It was during extensive testing of the technology that the UTSA team realized they’d come so far on the project. They reached out to international research exchanges in Brazil. The team under the leadership of Betal noticed something interesting. The experimental demonstration of UTSA’s remotely controlled medical robot was performed in late 2016.
“We were intrigued and initially puzzled at the fact that nanoparticles larger than the opening of a cell membrane’s channels could actually enter inside,” said Guo.
The research was supported in part by the National Science Foundation (Grant no. NSF 1002380), by the U.S. Department of Defense (Grant no. W911NF-12-1-0082) and by the UTSA Office of the Vice President for Research, Economic Development and Knowledge Enterprise.
“Their abilities leave room for much hope,” Guo said. “We believe cancerous cells may be specifically targeted for treatment eliminating the need for some chemotherapy treatments, and Alzheimer’s disease victims could possibly receive special treatments by aligning cells which have ceased to live in the brain. There is still much work to be done, but we are very happy for this recognition and the potential that lies ahead.”
Betal, Guo, and Bhalla has published their research of world’s smallest medical robot early this year in Nature–Scientific Reports, very, few get a spot in Guinness alongside fingernail guy, the Big Mac enthusiast, a speedy finger snapper, my friend Jeff, and a man willing to let a chainsaw near his face.
