  2. It can measure the biological activity of neurons and dynamics of vortices in superconductors.

Select the correct code

  • a. 
  • b. 
  • c. 
  • d. 
Answer : b

Quantum diamond microscope

  • Researchers from the Indian Institutes of Technology (IIT) at Mumbai and Kharagpur have built a microscope that can image magnetic fields within microscopic two-dimensional samples that change over milliseconds.
  • This has a huge potential for scientific applications, such as in measuring biological activity of neurons and dynamics of vortices in superconductors.
  • This is the first time that such a tool has been built to image magnetic fields that change within milliseconds. 
  • The key aspect of this sensor is a “nitrogen vacancy (NV) defect centre” in a diamond crystal.
  • Such NV centres act as pseudo atoms with electronic states that are sensitive to the fields and gradients around them (magnetic fields, temperature, electric field and strain).
