Cilmi-baarayaal ka socda Waaxda Farsamada iyo Aerospace Engineering (MAE) ee Dugsiga Herbert Wertheim ee Injineerinka ayaa soo saaray nooc cusub oo xuubka dhiig-baxa ah oo ka samaysan graphene oxide (GO), kaas oo ah walxo lakabyo monoatomic ah.Waxa la filayaa inay si buuxda u beddesho daawaynta sifaynta kelyaha si samir leh.Horumarkani waxa uu u ogolaanayaa sifeeye-yaraha in lagu xidho maqaarka bukaanka.Ku shaqaynta cadaadiska halbowlaha, waxay baabi'in doontaa bamka dhiigga iyo wareegga dhiigga ee ka baxsan jidhka, taas oo u oggolaanaysa sifeynta badbaadada ee raaxada gurigaaga.Marka la barbar dhigo xuubka polymer-ka ee jira, qulqulka xuubka ayaa ah laba amar oo sarreeya, wuxuu leeyahay iswaafajinta dhiigga, mana fududa in la cabbiro sida xuubabka polymerka.
Professor Knox T. Millsaps oo ka tirsan MAE isla markaana hormuud ka ah cilmi-baadhaha mashruuca xuubka Saeed Moghaddam iyo kooxdiisu waxay soo saareen hannaan cusub oo ku lug leh isku-ururinta iyo hagaajinta sifooyinka jidheed iyo kiimikaad ee GO nanoplatelets.Habkani waxa uu kaliya u rogayaa lakabyada 3 GO isu imaatinyo nanosheet ah oo si heer sare ah loo agaasimay, si loo gaaro awood aad u sareysa iyo xulashada."Annaga oo horumarinayna xuubka si aad ah uga sii daaran marka loo eego dhiggiisa noolaha, xuubka hoose ee glomerular (GBM) ee kelyaha, waxaan muujinnay awoodda weyn ee nanomaterials, nanoengineering, iyo isku-ururinta molecular."Mogda Dr. Mu ayaa tiri.
Daraasadda waxqabadka xuubka ee xaaladaha hemodialysis waxay soo saartay natiijooyin aad u dhiirigelinaya.Isku-dhafka miirayaasha ee urea iyo cytochrome-c waa 0.5 iyo 0.4, siday u kala horreeyaan, kuwaas oo ku filan sifaynta gaabis ah ee muddada dheer iyada oo la sii hayo in ka badan 99% albumin;Daraasadaha ku saabsan hemolysis-ka, kicinta dhammaystirka iyo xinjirowga ayaa muujiyay inay la mid yihiin agabka xuubka sifaynta ee jira Ama ka wanaagsan waxqabadka xuubka sifaynta ee jira.Natiijooyinka daraasaddan waxaa lagu daabacay Waddooyin Hormarsan Interfaces (Febraayo 5, 2021) ee hoos yimaada ciwaanka "Trilayer Interlinked Graphene Oxide Membrane ee Hemodialyzer Wearable".
Dr. Moghaddam ayaa yiri: "Waxaan soo bandhignay GO nanoplatelet gaar ah oo iskood isu abaabulay oo dalbaday mosaic, kaas oo si weyn u horumarinaya dadaalka tobanka sano ah ee horumarinta xuubabka graphene."Waa madal shaqayn karta oo kor u qaadi karta sifaynta habeenkii socodka hoose ee guriga.Dr. Moghaddam wuxuu hadda ka shaqeynayaa horumarinta microchips-yada iyadoo la adeegsanayo xuubka cusub ee GO, kaas oo u keeni doona cilmi-baaris ku dhow xaqiiqda bixinta qalabyada hemodialysis ee xiran ee bukaannada cudurrada kelyaha.
Tifaftirka dabeecadda (Maarso 2020) ayaa tiri: “Ururka Caafimaadka Adduunka ayaa ku qiyaasey in ku dhawaad 1.2 milyan oo qof ay u dhintaan kelyo-gabka sannad kasta adduunka oo dhan [iyo dhacdooyinka cudurka kelyaha ee heerka-dambe (ESRD) waxaa sabab u ah sonkorowga iyo dhiig-karka]….Sifeynta Sifeynta Isku-darka xaddidaadyada wax-ku-oolka ah ee tignoolajiyada iyo awood-u-helidda waxay sidoo kale ka dhigan tahay in wax ka yar kala bar dadka u baahan daawaynta ay heli karaan."Qalabka la gashado ee si habboon loo yareeyey ayaa ah xal dhaqaale si loo kordhiyo heerarka badbaadada, gaar ahaan horumarka Shiinaha."Xubabkayagu waa qayb muhiim ah oo ka mid ah nidaam yar oo la xidhan karo, kaas oo soo saari kara shaqada sifaynta kelyaha, si weyn u hagaajinaya raaxada iyo la awoodi karo adduunka oo dhan," ayuu yidhi Dr. Moghaddam.
"Horumarka muhiimka ah ee daaweynta bukaanada qaba dhiigbaxa dhiigbaxa iyo kelyaha ee shaqada ayaa xaddiday tignoolajiyada xuubabka.Tignoolajiyada Membrane may samayn horumar la taaban karo dhawrkii sano ee la soo dhaafay.Horumarka aasaasiga ah ee tignoolajiyada xuubka waxay u baahan tahay hagaajinta sifaynta kelyaha.Qalab heersare ah oo la dami karo oo la xushay, sida xuubabka graphene oxide ee aadka u dhuuban ee halkan lagu sameeyay, ayaa laga yaabaa inay beddelaan jaantuska.Xuubabka aadka u dhuuban ee aadka u khafiifka ah ma ogaan karaan kaliya sifeeyaha yar yar, laakiin sidoo kale aaladaha la qaadan karo ee dhabta ah iyo kuwa xiran kara, si kor loogu qaado tayada nolosha iyo saadaasha bukaanka."James L. McGrath ayaa sheegay in uu yahay borofisar ku takhasusay injineernimada biomedical ee Jaamacadda Rochester iyo la-hawlgaliyaha tignoolajiyada cusub ee xuubka silikon khafiifka ah ee codsiyada kala duwan ee bayooloji (Nature, 2007).
Cilmi-baaristan waxaa maalgeliyay Machadka Qaranka ee Sawir-qaadista Biomedical iyo Bioengineering (NIBB) oo hoos yimaada Machadyada Caafimaadka Qaranka.Kooxda Dr. Moghaddam waxaa ka mid ah Dr. Richard P. Rode, oo ah dhakhtar sare oo ka tirsan UF MAE, Dr. Thomas R. Gaborski (baaritaan la wadaaga), Daniel Ornt, MD (la-baaraha maamulaha), iyo Henry C oo ka tirsan Waaxda Biomedical. Injineernimada, Rochester Institute of Technology .Dr. Chung iyo Hayley N. Miller.
Dr. Moghaddam waa xubin ka mid ah UF Interdisciplinary Microsystems Group wuxuuna hoggaamiyaa Nanostructured Energy Systems Laboratory (NESLabs), oo hadafkiisu yahay in la wanaajiyo heerka aqoonta nanoengineering ee qaababka dalool ee shaqaynaya iyo fiisigiska gudbinta micro/nanoscale.Waxa uu isu keenaa qaybo badan oo injineernimada iyo sayniska ah si ay si fiican u fahmaan fiisigiska gudbinta mikro/nano-nano una horumariyaan qaab-dhismeedka jiilka xiga iyo nidaamyada leh waxqabad sare iyo hufnaan.
