Procedure for rapid mode of detection. The magnetic microparticles are first mixed with undiluted serum/plasma for five minutes and shaken by hand to capture SARS-CoV-2 antibodies. After rinsing using a magnetic rack to remove the other interfering factors, polystyrene microparticles are added for another five minutes and shaken by hand. Next, the solution is dispensed into the loading chamber of the microfluidic device. After entering the micro-channel, within 10 minutes, an accumulation of polystyrene microparticles is formed that is visible to the naked eye.
