Magalasi okhala ndi ma nanoparticles agolide apangidwa kuti azitha kuwongolera khungu lamtundu wobiriwira.
Khungu la khungu ndi mkhalidwe womwe mithunzi ina ingawoneke ngati yosamveka kapena yosazindikirika - kupangitsa zochitika za tsiku ndi tsiku kukhala zovuta.
magalasi achikuda pa intaneti
Mosiyana ndi magalasi okhala ndi utoto wobiriwira wakhungu, magalasi opangidwa ndi gulu la UAE ndi UK atha kugwiritsidwanso ntchito kukonza zovuta zina za masomphenya.
Ndipo chifukwa amagwiritsa ntchito zinthu zopanda poizoni, alibe mavuto azaumoyo omwe amadziwika ndi magalasi am'mbuyomu omwe amagwiritsa ntchito utoto wofiira.
Komabe, kafukufuku wina akuwonetsa kuti magalasi asanafike pamsika wamalonda, amafunika kuwunikiridwa pamayesero azachipatala.
Magalasi apadera olumikizirana apangidwa okhala ndi ma nanoparticles agolide ndi kusefa kopepuka kuti athandizire kuwongolera khungu, lipoti la kafukufuku (chithunzi cha masheya)
Kafukufukuyu adachitidwa ndi injiniya wamakina Ahmed Salih ndi anzawo ku Khalifa University ku Abu Dhabi.
"Kusokonekera kwamtundu ndi vuto lobadwa nalo la diso lomwe limakhudza 8% ya amuna ndi 0.5% ya azimayi," ofufuzawo adalongosola m'mapepala awo.
Mitundu yofala kwambiri ya matendawa ndi yofiira-khungu ndi yofiira - yomwe imadziwika kuti "khungu la mtundu wofiira-wobiriwira" - lomwe, monga momwe dzinalo likusonyezera, zimapangitsa kuti zikhale zovuta kuti anthu azisiyanitsa zobiriwira ndi zofiira.
"Chifukwa palibe mankhwala a matendawa, odwala amasankha zovala zomwe zimathandiza kuti maonekedwe awonekere," anawonjezera ofufuzawo.
Makamaka, anthu omwe ali ndi khungu lofiira-wobiriwira amavala magalasi ofiira omwe amapangitsa kuti mitunduyo ikhale yosavuta kuwona - koma magalasiwa nthawi zambiri amakhala ochuluka ndipo sangagwiritsidwe ntchito kukonza mavuto ena a maso nthawi imodzi.
Chifukwa cha zofooka zimenezi, ofufuza posachedwapa ayamba kugwiritsa ntchito magalasi opangidwa mwapadera.
Tsoka ilo, ngakhale magalasi opaka utoto wa pinki adapangitsa kuti wovalayo aziwona zobiriwira zobiriwira pamayesero azachipatala, onse adachotsa utotowo, zomwe zidapangitsa kuti azikhala ndi nkhawa zokhudzana ndi chitetezo komanso kulimba kwawo.
Khungu la khungu ndi mkhalidwe womwe mitundu ingawonekere yosamveka kapena yovuta kusiyanitsa.
M'malo mwake, a Saleh ndi anzawo adatembenukira ku tinthu tating'ono ta golide. Izi sizowopsa ndipo zakhala zikugwiritsidwa ntchito kwa zaka mazana ambiri kupanga "galasi la cranberry" lamtundu wa rozi chifukwa cha momwe amamwazira kuwala.
Kuti apange magalasi olumikizirana, ofufuzawo adasakaniza ma nanoparticles agolide mu hydrogel, chinthu chapadera chopangidwa ndi netiweki ya ma polima olumikizana.
Izi zimapanga gel ofiira omwe amasefa kuwala kwa mafunde pakati pa 520-580 nanometers, gawo la sipekitiramu pomwe zofiira ndi zobiriwira zimadutsana.
Magalasi ogwira mtima kwambiri, ofufuzawo akuti, anali omwe adapangidwa ndi tinthu tating'ono ta golide tokhala ndi ma nanometer 40 omwe sanagwirizane kapena kusefa kuwala kochulukirapo kuposa momwe amafunikira.
Bambo Salih ndi anzawo adatembenukira ku tinthu ting'onoting'ono tagolide, topanda poizoni ndipo takhala tikugwiritsa ntchito kwazaka mazana ambiri kupanga 'galasi la cranberry' lamtundu wa rozi, lomwe lili pano.
Kuti apange magalasi olumikizana, ofufuzawo adasakaniza ma nanoparticles agolide mu hydrogel. Izi zimapanga gel osakaniza amtundu wa rose omwe amasefa mafunde opepuka pakati pa 520-580 nanometers, gawo la sipekitiramu pomwe zofiira ndi zobiriwira zimalumikizana.
Magalasi a nanoparticle agolide alinso ndi zinthu zosungira madzi monga magalasi wamba omwe amapezeka pamalonda.
Ndi kafukufuku woyambirira watha, ofufuzawo tsopano akuyang'ana kuti achite mayesero azachipatala kuti adziwe chitonthozo cha magalasi atsopano.
Pafupifupi munthu mmodzi mwa anthu 20 alionse ndi osaona, zomwe zimapangitsa dziko kukhala lodetsa nkhawa kwambiri.
Pali mitundu inayi ya khungu la mitundu, yomwe imadziwika kuti red blindness, double blindness, trichromatic blindness, ndi color blindness.
Kufiira kumaphatikizapo chilema kapena kusapezeka kwa maselo aatali atalitali mu retina;ma cones a photoreceptor awa ali ndi udindo wozindikira kuwala kofiyira.MaProtans adapeza zovuta kusiyanitsa chofiira ndi chobiriwira, ndi buluu ndi chobiriwira.
Deuteranopia ndi chikhalidwe chomwe ma cones obiriwira osamva kuwala akusowa mu retina.Chotsatira chake, ma deutans amavutika kusiyanitsa pakati pa zobiriwira ndi zofiira, ndi zina zotuwa, zofiirira, ndi zobiriwira.Pamodzi ndi khungu lofiira, izi ndi imodzi mwa mitundu yofala kwambiri ya khungu lamtundu.
Tritanopia ndi maselo afupiafupi a cone mu retina omwe salandira kuwala kwa buluu nkomwe.Anthu omwe ali ndi mtundu wosowa kwambiri wakhungu amasokoneza kuwala kwa buluu ndi imvi, wofiirira wakuda ndi wakuda, wobiriwira wapakati ndi buluu, ndi lalanje ndi zofiira.
Anthu omwe ali ndi khungu lathunthu sangathe kuzindikira mtundu uliwonse ndipo amatha kuona dziko lakuda ndi loyera ndi mithunzi ya imvi.
magalasi achikuda pa intaneti
Ndodo zimagwira ntchito m'malo otsika kwambiri, pomwe ma cones amagwira ntchito masana ndipo ali ndi udindo wamtundu.
Malingaliro omwe ali pamwambawa ndi a ogwiritsa ntchito athu ndipo samangowonetsa malingaliro a MailOnline.
