Cov tshuaj tiv thaiv kab mob tshiab no xav tias yuav siv rau cov kab mob xws li mob qhua pias mus txog Covid-19. Muaj kev tshaj tawm tias cov tshuaj tiv thaiv kab mob tshiab no yog ua los ntawm cov khoom me me poly(lactic-co-glycolic acid) (PLGA). PLGA yog ib qho khoom siv polymer organic uas lwj tau, uas tsis muaj tshuaj lom thiab muaj kev sib raug zoo zoo. Nws tau pom zoo rau kev siv rau hauv Implants, sutures, kho cov ntaub ntawv, thiab lwm yam.
