Ubuzima: Guhuza amabara-gukosora lens ya konte ikoresha zahabu nanoparticles kugirango uyungurure urumuri

Lens ya contact irimo zahabu nanoparticles yatejwe imbere iyungurura urumuri kugirango ifashe gukosora ibara ritukura-icyatsi kibisi.
Ubuhumyi bwamabara nuburyo igicucu gishobora kugaragara ko cyacecetse cyangwa kitamenyekana - bigatuma ibikorwa bya buri munsi bigorana.

Bitandukanye n'ibirahuri byahinduwe kugirango impumyi zitukura-icyatsi kibisi, lens yakozwe nitsinda rya UAE hamwe nu Bwongereza naryo rishobora gukoreshwa mugukosora ibindi bibazo byerekezo.
Kandi kubera ko bakoresha ibikoresho bidafite uburozi, ntabwo bafite ibibazo byubuzima bishobora kurangwa na lens prototype yabanje gukoresha irangi ritukura.
Nyamara, ubushakashatsi bumwe bwerekana ko mbere yuko lens zigera ku isoko ry’ubucuruzi, zigomba gusuzumwa mu bigeragezo by’amavuriro.
Hashyizweho uburyo bwihariye bwo guhuza amakuru burimo nanoparticles ya zahabu no kuyungurura urumuri kugirango bifashe gukosora ubuhumyi bwamabara, raporo yubushakashatsi (ishusho yimigabane)
Ubushakashatsi bwakozwe na injeniyeri w’ubukanishi Ahmed Salih na bagenzi be bo muri kaminuza ya Khalifa i Abu Dhabi.
Abashakashatsi basobanuye mu nyandiko yabo bati: "Kubura amabara ni indwara ivuka y'amaso yibasira 8% by'abagabo na 0.5% by'abagore."
Ubwoko bw'indwara bukunze kugaragara ni ubuhumyi butukura n'ubuhumyi butukura - hamwe bizwi ku izina rya “impumyi itukura-icyatsi kibisi” - nk'uko izina ribigaragaza, bigora abantu gutandukanya icyatsi n'umutuku.
Abashakashatsi bongeyeho bati: "Kubera ko nta muti ushobora gukiza indwara, abarwayi bahitamo kwambara bifasha kongera imyumvire y'amabara".
By'umwihariko, abantu bafite ubumuga bwo kutabona-icyatsi kibisi bambara ibirahuri bitukura byorohereza kubona ayo mabara - ariko ibirahuri akenshi ni binini kandi ntibishobora gukoreshwa mugukosora ibindi bibazo byerekezo icyarimwe.
Kubera izo mbogamizi, abashakashatsi baherutse kwitabaza uburyo bwihariye bwo guhuza amakuru.
Kubwamahirwe, mugihe uturemangingo twibara twijimye twijimye twateje imbere uwambaye imyenda yumutuku-icyatsi mubigeragezo byamavuriro, bose barangije irangi, bituma bahangayikishwa numutekano wabo nigihe kirekire.
Ubuhumyi bwamabara nuburyo amabara ashobora kugaragara acecetse cyangwa bigoye gutandukanya undi.Figure: Ibintu byamabara bigaragara muburyo butandukanye bwubuhumyi bwamabara
Ahubwo, Bwana Saleh na bagenzi be bahindukiriye uduce duto twa zahabu.Ibi ntabwo ari uburozi kandi bimaze ibinyejana byinshi bikoreshwa mu gukora ibara ryitwa "cranberry ikirahure" kubera uburyo bakwirakwiza urumuri.
Gukora lensisiti yo guhuza, abashakashatsi bavanze nanoparticles ya zahabu muri hydrogel, ibikoresho bidasanzwe bikozwe murusobe rwa polymers ihuza.
Ibi bitanga gel itukura iyungurura uburebure bwumurambararo hagati ya nanometero 520-580, igice cyurwego aho umutuku nicyatsi kibisi.
Abashakashatsi bavuga ko uburyo bwiza bwo guhuza amakuru, ari bwo bwakozwe hamwe na nanometero 40 z'ubugari bwa zahabu zidafatanye hamwe cyangwa ngo zungurure urumuri kuruta uko byari bikenewe.
Bwana Salih na bagenzi be bahindukiriye uduce duto twa zahabu, tudafite uburozi kandi bukaba bwarakoreshejwe mu binyejana byinshi mu gukora ibara ry’ibara rya 'cranberry ikirahure', ku ishusho hano
Kugirango ukore lensisiti yo guhuza, abashakashatsi bavanze nanoparticles ya zahabu muri hydrogel.Ibyo bitanga gel ifite ibara rya roza iyungurura uburebure bwumucyo uri hagati ya nanometero 520-580, igice cyurwego aho umutuku nicyatsi kibisi.
Lens ya nanoparticle ifite kandi uburyo bwo kubika amazi asa nubucuruzi busanzwe buboneka.
Hamwe nubushakashatsi bwibanze burangiye, abashakashatsi ubu barashaka gukora ibizamini byamavuriro kugirango bamenye ihumure rishya.
Abantu bagera kuri 1 kuri 20 ni amabara, ibintu bituma isi iba ahantu habi.
Hariho ubwoko bune bwubuhumyi bwamabara, buzwi nkubuhumyi butukura, ubuhumyi bubiri, ubuhumyi butatu, nubuhumyi bwamabara.
Redblindness ikubiyemo inenge cyangwa kubura ingirabuzimafatizo ndende ya cone muri retina;iyi fotoreceptor cones ishinzwe kumva itara ritukura.Abaprotani basanze bigoye gutandukanya umutuku nicyatsi, nubururu nicyatsi.
Deuteranopia ni imiterere aho ibara ryatsi ryumva urumuri rwabuze muri retina.Nkigisubizo, abadutani bafite ikibazo cyo gutandukanya icyatsi nicyatsi gitukura, hamwe nicyatsi, ibara ry'umuyugubwe, nicyatsi-ubururu.Mu buhumyi butukura, ibi ni bumwe muburyo busanzwe bwo guhuma amabara.
Tritanopiya ni selile ngufi-ya cone selile muri retina itakira urumuri rwubururu na gato.Abantu bafite ubu buryo budasanzwe bwo guhuma amabara bitiranya ubururu bwerurutse bwerurutse nicyatsi, umutuku wijimye wijimye, icyatsi kibisi hamwe nubururu, na orange numutuku.
Abantu bafite ubuhumyi bwuzuye ntibashobora kubona ibara na rimwe kandi barashobora kubona isi gusa mwirabura n'umweru kandi igicucu cy'imvi.

Inkoni ikora mumucyo muke, mugihe cones ikora kumanywa kandi ishinzwe ibara.Abantu bafite ubumuga bwo kutabona bafite ibibazo byingirabuzimafatizo.
Ibitekerezo byavuzwe haruguru nibyo byabakoresha bacu kandi ntabwo byanze bikunze byerekana ibitekerezo bya MailOnline.
