Kit and method for detecting coronavirus

A method for detecting Coronavirus comprising the steps of:

• preparing magnetic nanoparticles with primers attached on the surface thereof;
• obtaining magnetic nanoparticles having amplified products on the surface by performing a polymerase chain reaction (PCR) by adding the magnetic nanoparticles with the primers attached to the surface to a sample containing Coronavirus;
• adding the magnetic nanoparticles with the amplified products on the surface in a reactor provided with an opening, covering the opening with a conductive substrate, and applying a magnetic field into the reactor from one side of the conductive substrate under a first condition;
• adding metal ions including any one or more of ruthenium (Ru), iron (Fe), silver (Ag), copper (Cu), nickel (Ni), cadmium (Cd) and zinc (Zn) into the reactor and then applying the magnetic field under a second condition;
• and
• providing first and second electrodes in the reactor, and measuring an electrochemical signal using the first and second electrodes and the conductive substrate together.
