Ma microneedles okhala ndi mabowo a PLA: kuzindikira mwachangu kwa antibody ya covid-19 popanda zitsanzo za magazi

Ofufuza aku Japan apanga njira yatsopano yogwiritsira ntchito ma antibodies kuti azindikire kachilombo ka corona koyambirira mwachangu komanso modalirika popanda kufunikira zitsanzo za magazi. Zotsatira za kafukufukuyu zafalitsidwa posachedwapa mu lipoti la Science.
Kusazindikira bwino anthu omwe ali ndi kachilombo ka covid-19 kwachepetsa kwambiri momwe anthu padziko lonse lapansi amayankhira COVID-19, zomwe zikuchulukirachulukira chifukwa cha kuchuluka kwa matenda osawonetsa zizindikiro (16% - 38%). Pakadali pano, njira yayikulu yoyesera ndikutenga zitsanzo popukuta mphuno ndi pakhosi. Komabe, kugwiritsa ntchito njira imeneyi kumachepetsedwa ndi nthawi yayitali yodziwira matendawa (maola 4-6), mtengo wokwera komanso zofunikira pa zida zaukadaulo ndi ogwira ntchito zachipatala, makamaka m'maiko omwe ali ndi ndalama zochepa.
Atatsimikizira kuti madzi amkati mwa thupi angakhale oyenera kuzindikira ma antibodies, ofufuza adapanga njira yatsopano yopezera zitsanzo ndi kuyesa. Choyamba, ofufuza adapanga tinthu tating'onoting'ono tomwe timatha kuwonongeka topangidwa ndi polylactic acid, tomwe timatha kutulutsa madzi amkati mwa thupi kuchokera pakhungu la munthu. Kenako, adapanga biosensor yochokera papepala yowunikira ma antibodies enieni a covid-19. Mwa kuphatikiza zinthu ziwirizi, ofufuza adapanga chigamba chaching'ono chomwe chingathe kuzindikira ma antibodies pamalopo mumphindi zitatu.
