Dr. Singh research focuses on epitaxial growth and characterization of nanoparticles, thin films and biomaterials using advanced sol-gel, e-beam and thermal evaporation techniques, electronic and magnetic properties using synchrotron based X-ray techniques, and studying how their transport and electronic properties evolve with system’s shape and size. The materials systems of interest include the epitaxial ferroelectric, magnetic, correlated oxide thin films, superconductor and heterostructures, and biological samples such as graphene oxide etc.
We synthesised the Fe3O4 nanoparticle coated with silica to help the hospital in RTPCR diagnosis for covid19. In one of the procedures, they need to immobilize the novel coronavirus RNA (actually work also for DNA and RNA in general) for separation. The material used for nucleic acid immobilization is called magnetic beads and it is high cost and highly demanded during a pandemic situation. We modified the Fe3O4 nanoparticle coated with silica as the beads material, from recent protocols. The XAS and XMCD spectra is as below:
