Kungani ibhekwa njengengcono kunokusula, ama-gel, okhilimu, izibulala-magciwane, isinqandakuvunda notshwala?
Kunesayensi esheshayo ngemuva kwalokhu.
Ngokomqondo, ukugeza ngamanzi kungasebenza ekuhlanzeni amagciwane anamathela ezandleni zethu. Ngeshwa, amagciwane ajwayele ukuhlangana nesikhumba sethu njengeglu, okwenza kube nzima ukuthi iwe.Ngakho-ke, amanzi awodwa akwanele, yingakho kufakwa insipho.
Ngamafuphi, amanzi afakwa kule nsipho aqukethe ama-amphiphilic molecule angama-lipids, ahleleke ngokufana nolwelwesi lwe-lipid lwegciwane. Lokhu kwenza ukuthi lezi zinto ezimbili zincintisane, futhi yile ndlela insipho uqobo isusa ngayo ukungcola ezandleni zethu.Ngokweqiniso, insipho ayikhululi nje kuphela "i-glue" phakathi kwesikhumba sethu namagciwane, iyababulala ngokususa okunye ukuxhumana zibophe ndawonye.
Yileyo ndlela amanzi anensipho ekuvikela ngayo ku-COVID-19, yingakho kulokhu kufanele usebenzise amanzi anensipho esikhundleni semikhiqizo esetshenziswa kakhulu yotshwala.
