Uru rubuga rukoreshwa nubucuruzi cyangwa ubucuruzi bufitwe na Informa PLC kandi uburenganzira bwose bubana nabo.Ibiro bya Informa PLC byanditse ni 5 Howick Place, London SW1P 1WG.Yiyandikishije mu Bwongereza na Wales.Numero 8860726.
Itsinda ry’abashakashatsi ba Cal Tech riyobowe na Wei Gao, umwarimu w’ubuhanga bw’ibinyabuzima, ryakoze sensor yambara ikurikirana urugero rwa metabolite nintungamubiri ziri mumaraso yumuntu mu gusesengura ibyuya byabo.Ibyuma byabize ibyuya byibanze ahanini bigizwe nibintu bigaragara cyane, nka electrolytite, glucose, na lactate.Iyi nshyashya irakomeye kandi itahura ibyuya byinshi murwego rwo hasi cyane.Biroroshye kandi gukora kandi birashobora gukorwa cyane.
Intego yitsinda ni sensor ituma abaganga bahora bakurikirana imiterere yabarwayi bafite uburwayi nkindwara zifata umutima, diyabete, nindwara zimpyiko, ibyo byose bikaba bishyira muburyo budasanzwe bwintungamubiri cyangwa metabolite mumaraso.Abarwayi byaba byiza mugihe umuganga wabo yari azi byinshi kumiterere yabo kandi ubu buryo bwirinda ibizamini bisaba inshinge no gupima amaraso.
Gao agira ati: "Ibyuma bikoresha ibyuya byinshi bishobora kwambara byihuse, bikomeza, kandi bidashobora gufata impinduka mu buzima ku rwego rwa molekile."â € œBashobora gutuma igenzura ryihariye, kwisuzumisha hakiri kare, no gutabara ku gihe bishoboka.â €
Rukuruzi rushingiye kuri microfluidics ikoresha amazi make, mubisanzwe binyuze mumiyoboro itarenze kimwe cya kane cya milimetero mubugari.Microfluidics ikwiranye neza na progaramu kuko igabanya ingaruka ziterwa no guhumeka ibyuya no kwanduza uruhu kumyumvire ya sensor.Nkuko ibyuya byatanzwe bishya bitembera muri mikorobe ya sensor, bipima neza ibigize ibyuya kandi bigafata impinduka mubitekerezo mugihe.
Kugeza ubu, Gao na bagenzi be bavuga ko ibyuma byifashishwa bya microfluidic bishingiye ku byuma byifashishwa ahanini byakozwe mu buryo bwa lithographie-evaporation, bisaba inzira yo guhimba bigoye kandi bihenze.Ikipe ye yahisemo gukora biosensor zayo muri graphene, ubwoko bwa karubone.Byombi bishingiye kuri graphene hamwe na microfluidics imiyoboro ikorwa mugushushanya impapuro za plastike hamwe na lazeri ya dioxyde de carbone, igikoresho gikunze kuboneka kubakunda urugo.
Itsinda ry’ubushakashatsi ryateguye sensor yaryo kugira ngo ripime igipimo cy’ubuhumekero n’umutima, hiyongereyeho aside irike na tirozine.Tyrosine yatoranijwe kubera ko ishobora kuba ikimenyetso cyerekana indwara ziterwa na metabolike, indwara z'umwijima, indwara ziterwa no kurya, ndetse n'indwara zo mu mutwe.Acide Uric yatoranijwe kubera ko, murwego rwo hejuru, ifitanye isano na gout, indwara ibabaza ingingo igenda yiyongera kwisi yose.Indwara ya Goutte ibaho iyo aside irike nyinshi mu mubiri itangiye koroha mu ngingo, cyane cyane iy'ibirenge, bigatera uburakari no gutwika.
Kugirango barebe uko sensor ikora neza, abashakashatsi barayipimishije kubantu bafite ubuzima bwiza nabarwayi.Kugenzura ibipimo bya tirozine ibyuya biterwa nubuzima bwumuntu, bakoresheje amatsinda abiri yabantu: abakinnyi batojwe hamwe nabantu bafite ubuzima bwiza.Nkuko byari byitezwe, sensor zerekanye urugero rwo hasi rwa tirozine mu icyuya cyabakinnyi.Kugira ngo bagenzure urugero rwa acide ya uric, abashakashatsi bakurikiranye ibyuya byitsinda ryabantu bafite ubuzima bwiza basiba, kandi na nyuma y’amasomo amaze kurya ifunguro rikungahaye kuri purineâ € ”mu biryo byahinduwe na aside irike.Rukuruzi rwerekanye aside irike izamuka nyuma yo kurya.Ikipe ya Gao yakoze ikizamini gisa nabarwayi ba gout.Rukuruzi rwerekanaga aside irike yabo yari hejuru cyane ugereranije nabantu bafite ubuzima bwiza.
Kugira ngo hamenyekane neza niba ibyo byuma bifata amajwi, abashakashatsi bashushanyije kandi basuzuma amaraso yatanzwe n'abarwayi ba goutte hamwe n'amasomo meza.Ibipimo bya sensor ya urugero rwa aside irike bifitanye isano cyane nurwego rwayo mumaraso yabo.
Gao avuga ko kumva byinshi bya sensor, hamwe no koroshya bishobora gukorwa, bivuze ko amaherezo bashoboye gukoreshwa n'abarwayi mu rugo kugira ngo bakomeze imiterere nka goutte, n'indwara z'umutima.Kugira amakuru nyayo yukuri kubuzima bwabo birashobora no gutuma abarwayi bahindura imiti nimirire yabo nkuko bisabwa.
