Question

What is the size of the nano medical robot that set a new Guinness World Record?
A.140 nanometres
B.130 nanometres
C.110 nanometres
D.120 nanometres

Answer 1

D.120 nanometres
The scientists have developed the smallest medical robot and set a new Guinness World Record. The device, which is of 120 nanometres in size, can interact with biological cells. These nanocomposite particles can assist to treat cancer and Alzheimer's in the future and one day it might lead to huge medical advancements. 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 converts pressure into electric potentials. The magneto-elasto-electric coupled effect in the nanocomposites acts as arms and legs that move the nanoparticle around to interact with targeted biological cells.

Answer 2

its answer is 120 nanometer which was discovered by Houston scientist
