Ishami ry'Umuryango w'Abibumbye ryita ku Buzima ndetse n'Ikigo cyo muri Amerika gishinzwe kurwanya indwara zemera ko aerosole ari bwo buryo bw'ibanze bwo gukwirakwiza virusi ya COVID-19. Aerosole ni uduce duto twamazi cyangwa ibindi bintu bishobora kuguma bihagaritswe mukirere igihe kirekire, bito bihagije kugirango byinjire mumyanya y'ubuhumekero.
Abantu barekura aerosole iyo bahumeka, inkorora, kuvuga, gutaka cyangwa kuririmba. Iyi aerosole irashobora kandi kuba irimo virusi iyo yanduye COVID-19. Guhumeka aerosole ya coronavirus ihagije birashobora gutuma umuntu arwara. Mugusaba abantu kwambara masike, kunoza uburyo bwo guhumeka mu nzu hamwe na sisitemu yo kuyungurura ikirere, kugabanya imikoreshereze yumuntu no kugabanya umubare wa aerosole mubidukikije nibyo byihutirwa mugukwirakwiza ikwirakwizwa rya aerosole ya COVID-19.
Ubushakashatsi kuri virusi nshya zandura ni akaga, kandi ni gake muri laboratoire zifite urwego rwo hejuru rw’ibinyabuzima. Ubushakashatsi bwose kugeza ubu kuri masike cyangwa kuyungurura neza mugihe cyicyorezo cyakoresheje ibindi bikoresho bitekereza kwigana ingano nimyitwarire ya aerosole ya SARS-CoV-2. Ubushakashatsi bushya butezimbere kuri ibyo, kugerageza ibisubizo bya saline ya aerosolize hamwe na aerosole irimo coronavirus yo mumuryango umwe na virusi itera COVID-19 ariko yanduza imbeba gusa.
Yun Shen na mugenzi we wa kaminuza ya George Washington, Danmeng Shuai bakoze akayunguruzo ka nanofiber gatanga umuyaga mwinshi binyuze mu gitonyanga cya fluoride ya polyvinylidene kugeza ku rudodo ruzunguruka rugera kuri nanometero 300 z'umurambararo - incuro zigera kuri 167 zoroshye kurusha umusatsi w'umuntu. Ubu buryo bwaremye imyenge ya micrometero nkeya ya diametre hejuru ya nanofibers, ibafasha gufata 99,9 ku ijana bya aerona ya coronavirus.
Tekinike yo kubyaza umusaruro, izwi nka electrospinning, irahenze kandi irashobora gukoreshwa mugukora cyane nanofiber muyunguruzi kubikoresho bikingira umuntu hamwe na sisitemu yo kuyungurura ikirere. Electrospinning isiga kandi electrostatike yumuriro kuri nanofibers, ikongerera ubushobozi bwo gufata aerosole, kandi ubwinshi bwayo bworoshye guhumeka mugihe wambaye akayunguruzo ka electrospun nanofiber.
Prof. Yun Shen yagize ati: "Ikoranabuhanga rya Electrospinning rirashobora koroshya igishushanyo mbonera no gukora masike na filtri yo mu kirere." Ati: "Gukoresha ikoranabuhanga rya electrospinning mugutezimbere ubwoko bushya bwa masike hamwe nayunguruzo rwo mu kirere bifite imikorere myiza yo kuyungurura, uburyo bwubukungu bushoboka ndetse nubunini. Kubasha guhaza ibyifuzo bya masike hamwe nayunguruzo rwikirere mumurima biratanga icyizere."
