Imyenda mishya ishobora kongera gukoreshwa ishobora gukuraho ingaruka mbi ku binyabuzima n'ibinyabutabire

Ibikoresho bivanze by'imyenda ya siponji ikoreshwa mu gukuraho imbogamizi z'ibinyabuzima n'ibinyabutabire. Ifoto ikomoka kuri Kaminuza ya Northwestern
Ibikoresho byinshi bya MOF bigizwe n'imitako y'ubwoya byakozwe hano bishobora gukoreshwa nk'igitambaro kirinda ingaruka z'ibinyabuzima n'ibinyabutabire.
Imyenda yica udukoko ikoresheje N-chloro kandi ikuraho uburozi ikoresha urufatiro rukomeye rwa zirconium metal organic (MOF)
Ibikoresho by’urusenda bigaragaza imikorere yihuse ya bagiteri za Gram-negative (E. coli) na bagiteri za Gram-positive (Staphylococcus aureus), kandi buri bwoko bushobora kugabanukaho logarithms 7 mu minota 5.
Ibikoresho bya MOF/fibre byuzuyemo chlorine ikora bishobora kwangiza mu buryo bwihariye kandi bwihuse sinapi ya sulfur na analogue yayo ya 2-chloroethyl ethyl sulfide (CEES) mu gihe kitarenze iminota 3.
Itsinda ry’abashakashatsi bo muri Kaminuza ya Northwestern ryakoze ikintu gishya gishobora gukuraho ibintu bitera ibinyabuzima (nk’icyorezo cya coronavirus gitera COVID-19) n’ibintu bitera ibinyabuzima (nk’ibikoreshwa mu ntambara z’ibinyabutabire).
Iyo umwenda umaze kwangirika, ibikoresho bishobora gusubira uko byari bimeze mbere binyuze mu buryo bworoshye bwo kuwusiga ibara ry'umweru.
“Kugira ibikoresho bifite imikorere ibiri bishobora guhagarika icyarimwe ibintu bihumanya ibidukikije n’ibikomoka ku binyabuzima ni ingenzi cyane kuko uburyo bwo guhuza ibikoresho byinshi kugira ngo uyu murimo urangire ari bwinshi cyane,” ibi ni byo byavuzwe na Omar Farha wo muri Kaminuza ya Northwestern, akaba n’impuguke mu by’ikoranabuhanga mu by’ibyuma cyangwa MOF, uyu ni wo musingi w’ikoranabuhanga.
Farha ni umwarimu w’ubutabire mu Ishuri ry’Ubugeni n’Ubumenyi rya Weinberg akaba n’umwanditsi w’ubushakashatsi. Ni umunyamuryango w’Ikigo Mpuzamahanga cy’Ubuhanga mu by’Ubutabire muri Kaminuza ya Northwestern.
Ibikoresho bya MOF/fibre bishingiye ku bushakashatsi bwakozwe mbere aho itsinda rya Farha ryakoze ikintu cya nanomaterial gishobora guhagarika imiti y’uburozi. Binyuze mu bikorwa bimwe na bimwe bito, abashakashatsi bashobora kongeramo imiti irwanya virusi n’imiti irwanya udukoko muri icyo kintu.
Faha yavuze ko MOF ari "ikiyiko cyo kwiyuhagira neza." Ibikoresho bingana na nano byakozwe bifite imyobo myinshi, ishobora gufata gaze, umwuka n'ibindi bintu nk'ikiyiko bifata amazi. Mu mwenda mushya w'ibice, umwobo wa MOF ufite katasiyo ishobora guhagarika imiti y'uburozi, virusi na bagiteri. Ibintu bito bito bishobora gusigwa ku myenda y'imyenda byoroshye.
Abashakashatsi basanze ibinyabutabire bya MOF/fiber byagaragaje imbaraga zihuse mu kurwanya SARS-CoV-2, ndetse na bagiteri za Gram-negative (E. coli) na bagiteri za Gram-positive (Staphylococcus aureus). Byongeye kandi, ibinyabutabire bya MOF/fiber byuzuyemo chlorine ishobora kwangiza vuba gaze ya sinapi n'ibindi binyabutabire byayo (2-chloroethyl ethyl sulfide, CEES). Utunyabutabire twa nanopores tw'ibikoresho bya MOF bitwikiriwe ku mwenda ni tunini bihagije kugira ngo ibyuya n'amazi bisohoke.
Farha yongeyeho ko iyi mashini ivanze ishobora kwaguka kuko ikenera gusa ibikoresho by'ibanze byo gutunganya imyenda bikoreshwa mu nganda. Iyo ikoreshejwe hamwe na mask, iyo mashini igomba kuba ishobora gukora icyarimwe: kurinda uwambaye mask virusi ziri hafi ye, no kurinda abantu bahuye n'uwanduye wambaye mask.
Abashakashatsi bashobora kandi gusobanukirwa ahantu ibikoresho bikora ku rwego rwa atome. Ibi bituma bo n'abandi babona isano hagati y'imiterere n'imikorere kugira ngo bakore ibindi bikoresho bivanze bishingiye kuri MOF.
Kubuza chlorine ikora ishobora kongera gukoreshwa mu myenda ya MOF ishingiye kuri zirconium kugira ngo hakurweho ingaruka mbi ku binyabuzima n'ibinyabutabire. Ikinyamakuru cya American Chemical Society, 30 Nzeri 2021.
