Due to the recent outbreak of COVID-19ongoing mutants, we developed a coronavirus variant protein microarray that includes all the current spike mutationsthe wild-type viral antigensapplied in detecting immune responsesdrug specificities. We filed the patientspublished our findings in the Analytical Chemistry. Besides massive production of the coronavirus protein microarray, we also collaborated with a scanner company, developed artificial intelligence software,collaborated with suppliers. We are welcome any sort of collaboration.
