Conventional and Nanotechnology-Based Sensing Methods for SARS Coronavirus (2019-nCoV)

Zero-dimensional quantum dots, spherical nanoparticles, one-dimensional CNTs, metal, metal oxide nanotubes and rods, and 2D nanomaterials such as graphene have also been widely used for sensing applications. Apart from the above-mentioned diagnostic methods, development of nanosensors to detect 2019-nCoV virus can be very helpful to identify and isolate the infected individuals and offer infected patients the required treatment on time.
