Ukuqubuka kwakamuva kwe-COVID-19 kugqugquzele ukufuna okukhulu kwezixazululo ezisebenzayo ezinganqanda ukusabalala kwaleli gciwane elibulalayo - kusuka kubacwaningi nososayensi abazibophezele ekutholeni isisombululo, kubakhiqizi nakubathengi abafuna imininingwane ethembekile. Kulesi sikhathi sokungaqiniseki, abaningi bafuna ulwazi mayelana nobuchwepheshe obungase busetshenziswe ukulwa naleli gciwane. Enye indlela efakazelwe ukusebenzisa ukukhanya kwe-UV.

Ukuphazamisa i-DNA yamagciwane ngokukhanya kwe-UV ukukhanya kwe-
UVC kuwubuchwepheshe obusetshenziswa ngokuvamile bokuvala inzalo obuye baboniswa buvala amagciwane anhlobonhlobo, okuhlanganisa- kodwa kungagcini nje ngo- MRSA, C. diff, E. Coli kanye ne-Pseudomonas. Ekusetshenzisweni amandla e-UVC amuncwa ama-nucleic acid ngaphakathi kwe-RNA ne-DNA, okuholela kumabhondi aqinile okuthi, ngesilinganiso esifanele, enze i-pathogen ingakwazi ukuzala futhi itheleleke. Ubude begagasi be-germicidal obusebenza kahle kakhulu buba nenani eliphakeme phakathi kuka-260 nm kuya ku-270 nm, indawo enhle lapho i-DNA imunca amandla e-UV.

Iminyaka eminingi, izibani ze-UV ze-mercury zazibhekwa njengesinqumo esingcono kakhulu. Kodwa-ke, amalambu anemikhawulo eminingana, okuhlanganisa ukusebenza okuphansi emazingeni okushisa esiqandisi, ukwakhiwa okuntekenteke, isikhathi eside sokufudumala, ubungozi bokuchayeka kwi-mercury, kanye nokukhishwa kwe-UV okulinganiselwe ku-254nm. Uma kuqhathaniswa, ama-UV light-emitting diode (ama-UVC LED) angalungiselelwa ukuthi akhiphe amaza afanele we-germicidal wavelengths futhi ahlinzeke ngokubulala amagciwane lapho kudingeka khona ngaphandle kwemikhawulo ephazamisa izibani ze-mercury.

Isixazululo esisebenzayo ekuhloleni ukusebenza kwe-COVID-19
Ukusetshenziswa kobuchwepheshe be-UVC be-LED endaweni kunika amandla ukubulawa kwamagciwane okuthembekile, okusheshayo, okudingekayo kakhulu kumadivayisi amancane kuya kwaphakathi nendawo, njengamakhompyutha aphathekayo, amafoni, amakhibhodi, izingubo zamehlo, okhiye nempahla yezokunakekelwa kwempilo. Ivimbela ukudluliswa kwamagciwane ayingozi ezindaweni ezibucayi kakhulu, okuhlanganisa izindawo zokunakekela ezibhedlela, amalabhorethri kanye nezindlu ezihlanzekile.

Ama-LED we-Klaran UVC awazange abonise ukusebenza kahle ngokumelene nama-superbugs, njenge-C. diff kanye ne-Methicillin-Resistant Staphylococcus Aureus (MRSA), kodwa futhi ayakwazi ukuzuza ukuncipha okuphawulekayo kwemithwalo yegciwane kanye nebhaktheriya ngemizuzwana.

Nakuba izifundo ziqinisekisile ukuthi ukukhanya kwe-UVC kungasebenza ngempumelelo ekulweni ne-SARS-COV izifundo ezengeziwe ezidingekayo ukuze kutholwe futhi kuqinisekiswe impendulo ethile yomthamo odingekayo ukuze kwenziwe i-COVID-19 isebenze ezindaweni nezinto ezisetshenziswayo.
