Ukuqhambuka kwamva nje kwe-COVID-19 kuye kwabangela ukuba kukhangelwe izisombululo ezisebenzayo ezinokuthintela ukusasazeka kwale ntsholongwane ibulalayo - ukusuka kubaphandi kunye noososayensi abazibophelele ekufumaneni isisombululo, kubavelisi kunye nabathengi abafuna ulwazi oluthembekileyo. Ngeli xesha lokungaqiniseki, abaninzi bafuna ulwazi malunga neetekhnoloji ezinokuthi zisetyenziswe ukulwa le ntsholongwane. Enye indlela eqinisekisiweyo kukusebenzisa isibane se-UV.

Ukuphazamisa i-DNA ye-pathogens kunye nokukhanya kwe-UV ukukhanya kwe-
UVC yiteknoloji esetyenziswa ngokuqhelekileyo inzala ebonakaliswe ukuba ingasebenzi uluhlu olubanzi lweentsholongwane, kubandakanywa-kodwa kungaphelelanga kwi-MRSA, C. diff, E. Coli kunye nePseudomonas. Kwisicelo samandla e-UVC afunxwa yi-nucleic acids ngaphakathi kwe-RNA kunye ne-DNA, okukhokelela kwi-covalent bonds ethi, kwidosi efanelekileyo, inokunika i-pathogen ingakwazi ukuvelisa kunye nokusulela. Obona bude busebenzayo bentsholongwane bubakho ngencopho ephakathi kwe-260 nm ukuya kwi-270 nm, eyona ndawo ifanelekileyo apho i-DNA ifunxa amandla e-UV.

Kwiminyaka emininzi, izibane ze-UV ze-mercury zazibhekwa njengeyona nto ingcono kakhulu. Nangona kunjalo, izibane zinemida eliqela, kubandakanywa umsebenzi ophantsi kumaqondo obushushu efriji, ulwakhiwo oluethe-ethe, ixesha elide lokufudumala, umngcipheko wokuvezwa kwemekyuri, kunye nokukhutshwa kwe-UV okulinganiselweyo kwi-254nm. Xa kuthelekiswa, i-UV light-emitting diodes (I-UVC LEDs) inokumiselwa ukuba ikhuphe kumaza afanelekileyo okubulala iintsholongwane kwaye ibonelele ngokuthembekileyo kwimfuno yokubulala iintsholongwane ngaphandle kwemida ethintela izibane zemercury.

Isisombululo esisebenzayo ekuvavanyeni ukusebenza kwe-COVID-19
Ukusetyenziswa kobuchwephesha be-UVC be-LED kumphezulu kwenza ukuba kubulawe iintsholongwane ezithembekileyo, ezikhawulezayo, eziyimfuneko kwizixhobo ezincinci ukuya kweziphakathi, ezinjengeelaptops, iifowuni, izitshixo, iimpahla zamehlo, izitshixo kunye nezixhobo zempilo. Ithintela ukusasazwa kweentsholongwane eziyingozi kwiindawo ezinobuthathaka kakhulu, kubandakanywa amacandelo okhathalelo lwesibhedlele, iilebhu kunye namagumbi acocekileyo.

Ii-LED ze-UVC ze-Klaran azizange zibonise ukuba zisebenza kakuhle ngokuchasene ne-superbugs, ezifana ne-C. diff kunye ne-Methicillin-Resistant Staphylococcus Aureus (MRSA), kodwa ziyakwazi ukufezekisa ukunciphisa okubonakalayo kwimithwalo yentsholongwane kunye nebhaktheriya ngemizuzwana.

Ngelixa uphononongo luqinisekisile ukuba ukukhanya kwe-UVC kunokusebenza ukulwa ne-SARS-COV izifundo ezongezelelweyo ziyafuneka ukumisela kunye nokuqinisekisa idosi-impendulo efunekayo ukwenza i-COVID-19 isebenze kwiindawo ezahlukeneyo kunye nezixhobo.
