Introduction
At present, the epidemic will continue for a certain period of time, and there is a risk of re outbreak at any time. The government's long-term large-scale nucleic acid testing will certainly increase the financial burden. Self testing will be the main way in the future. The existing self-test methods are difficult to report and easy to make false reports. The reaction principle of this case is the same as the existing antigen detection principle: the test paper is composed of colloidal gold, positive and negative two-dimensional codes. When used, the test solution reacting with saliva or nasal fluid is painted on the test paper, and the N protein in the test solution seeps into the lower layer of the test paper through capillary action. If the N protein in saliva does not carry virus, the positive display layer will not react and display, and the negative two-dimensional code will be displayed in the next layer, If it is positive, the positive QR code will be displayed and the negative QR code will be completely covered.
