Imyenda mishya ishobora gukoreshwa irashobora gukuraho ibinyabuzima na chimique

Porogaramu ishobora guterwa na kristaline sponge yimyenda ikoreshwa mugukuraho ibinyabuzima na chimique. Inkomoko y'amashusho: Kaminuza ya Northwestern
Ibikoresho byinshi bya MOF bishingiye kuri fibre yibikoresho byakozwe hano birashobora gukoreshwa nkigitambara kirinda ibinyabuzima n’ibinyabuzima.
Imikorere myinshi kandi ishobora kuvugururwa N-chloro ishingiye ku miti yica udukoko no kwangiza imyanda ikoresha icyuma gikomeye cya zirconium (MOF)
Ibikoresho bya fibre yibikoresho byerekana ibikorwa byihuse byibinyabuzima birwanya Gram-negative bacteri (E. coli) na Gram-positif ya Gram-positif (Staphylococcus aureus), kandi buri tsinda rishobora kugabanuka kugera kuri 7 logarithm mu minota 5.
MOF / fibre igizwe na chlorine ikora irashobora guhitamo no kwangiza vuba sinapi ya sulfure na analogue ya chimique 2-chloroethyl ethyl sulfide (CEES) hamwe nubuzima bwa kimwe cya kabiri kitarenze iminota 3
Itsinda ry’ubushakashatsi ryaturutse muri kaminuza y’amajyaruguru y’iburengerazuba ryateguye imyenda myinshi ishobora gukuraho ibinyabuzima (nka coronavirus nshya itera COVID-19) hamwe n’iterabwoba ry’imiti (nk'izikoreshwa mu ntambara y’imiti).
Iyo umwenda umaze kubangamiwe, ibikoresho birashobora gusubizwa uko byahoze hakoreshejwe uburyo bworoshye bwo guhumanya.
Omar Farha wo muri kaminuza ya Northwestern, akaba ari icyuma-nganda cyangwa impuguke za MOF yagize ati: "Kugira ibikoresho bibiri bishobora gukora icyarimwe gukora uburozi bwa chimique na biologiya ni ngombwa kuko bigoye guhuza ibikoresho byinshi kugirango urangize iki gikorwa ni byinshi cyane". , iyi niyo shingiro ryikoranabuhanga.
Farha ni umwarimu wa chimie mu ishuri ry’ubukorikori n’ubumenyi rya Weinberg akaba n'umwanditsi umwe w’ubwo bushakashatsi. Ni umunyamuryango w'ikigo mpuzamahanga cya Nanotehnologiya muri kaminuza ya Northwestern.
MOF / fibre yibigize ishingiye kubushakashatsi bwakozwe mbere aho itsinda rya Farha ryakoze nanomaterial ishobora kudakora imiti yubumara. Binyuze mubikorwa bito, abashakashatsi barashobora kandi kongeramo imiti igabanya ubukana bwa antibacterial.
Faha yavuze ko MOF ari “sponge yuzuye yo koga.” Ibikoresho bingana na Nano byakozwe hamwe n’imyobo myinshi, ishobora gufata gaze, imyuka nibindi bintu nka sponge imitego y'amazi. Mu mwenda mushya uhuriweho, cavit ya MOF ifite catalizator ishobora kudakora imiti yuburozi, virusi na bagiteri. Nanomateriali nini irashobora gutwikirwa byoroshye kumyenda yimyenda.
Abashakashatsi basanze ibihimbano bya MOF / fibre byerekanaga ibikorwa byihuse kurwanya SARS-CoV-2, ndetse na bagiteri ya Gram-negative (E. coli) na bacteri za Gram-positif (Staphylococcus aureus). Byongeye kandi, MOF / fibre igizwe na chlorine ikora irashobora gutesha agaciro gazi ya sinapi hamwe n’ibigereranyo byayo (2-chloroethyl ethyl sulfide, CEES). Nanopores yibikoresho bya MOF bitwikiriye imyenda ni nini bihagije kugirango ibyuya n'amazi bihunge.
Farha yongeyeho ko ibyo bikoresho byose ari byinshi kuko bisaba gusa ibikoresho by'ibanze byo gutunganya imyenda bikoreshwa mu nganda. Iyo ikoreshejwe ifatanije na mask, ibikoresho bigomba gushobora gukora icyarimwe: kurinda uwambaye mask kwirinda virusi hafi yabo, no kurinda abantu bahura numuntu wanduye wambaye mask.
Abashakashatsi barashobora kandi gusobanukirwa urubuga rukora rwibikoresho kurwego rwa atome. Ibi bibafasha nabandi kuvana imiterere-imikorere yubusabane kugirango bakore ibindi bikoresho bishingiye kuri MOF.
Kwimura chlorine ikora ishobora kuvugururwa muri zirconium ishingiye kuri MOF yimyenda kugirango ikureho ibinyabuzima na chimique. Ikinyamakuru cya Sosiyete y'Abanyamerika y'Abashakashatsi, ku ya 30 Nzeri 2021.
