Dukoresha kuki kugirango tuzamure uburambe.Mu gukomeza gushakisha kururu rubuga wemera gukoresha kuki. Andi makuru.
Mu bushakashatsi buherutse gusohoka mu kinyamakuru Scientific Reports, lens ya contact ya biocompatible na elastique plasmonic contact lens yahimbwe hakoreshejwe polydimethylsiloxane (PDMS).
Ubushakashatsi: Ibice bibiri-biocompatible plasma ihuza lens yo gukosora ubuhumyi bwamabara. Inguzanyo yerekana amashusho: Sergey Ryzhov / Shutterstock.com
Hano, igishushanyo cyibanze kidahenze cyo gukosora ibara ritukura-icyatsi kibisi cyateguwe kandi gipimwa hashingiwe kuri nanolithographe yoroheje.
Imyumvire yumuntu yakomotse kuri selile eshatu zifata fotoreceptor selile, ndende (L), hagati (M), na conge ngufi (S), zikenerwa mukubona amabara atukura, icyatsi, nubururu, hamwe na sensibilité ya spécialité ntarengwa 430 , 530 na 560 nm.

Ubuhumyi bwamabara, buzwi kandi nkibura ryamabara (CVD), nindwara yijisho ribuza gutahura no gusobanura amabara atandukanye na selile eshatu zifotora zikora mubyerekezo bisanzwe kandi bigakora ukurikije sensibilité sensibilité maxima.Iyi ndwara yijisho, ishobora kuba intagondwa cyangwa irondakoko, iterwa no gutakaza cyangwa inenge muri selile ya Photoreceptor.

Dichroism ibaho mugihe bumwe mubwoko butatu bwa cone Photoreceptor selile idahari rwose;kandi ishyirwa mubikorwa nka proteophthalmia (nta fotoreptept ya cone itukura), deuteranopiya (nta fotoreptor yicyatsi kibisi), cyangwa ubuhumyi bwamabara ya trichromatic (kubura fotoreptept yubururu).
Monochromaticity, uburyo busanzwe bwo guhuma amabara, burangwa no kubura byibuze ubwoko bubiri bwa fotoreceptor selile.
Monochromatics yaba ifite ibara ryuzuye (ibara ryamabara) cyangwa ifite fotorepteptor yubururu gusa.Ubwoko bwa gatatu bwa trichromacy idasanzwe ibaho iyo imwe mumyanya mikorere ya selile ya cone.
Aberrant trichromacy igabanijwemo ubwoko butatu bushingiye ku bwoko bwa cone Photoreceptor inenge: deuteranomaly (icyatsi kibisi cya fotoreceptors), protanomaly (fotoreceptors itukura ifite inenge), na tritanomaly (selile yubururu bwa cone Photoreceptors).
Protans (protanomaly na protanopiya) na deutans (deuteranomaly na deuteranopia), bakunze kwita protanopiya, ni ubwoko busanzwe bwo guhuma amabara.
Protanomaly, impagarike yimikorere ya selile yumutuku itukura ihinduranya ubururu, mugihe sensitivite maxima ya selile yicyatsi kibisi ihinduranya umutuku.Bitewe nubwumvikane buke bwimyumvire yibyatsi bifotora icyatsi kibisi numutuku, abarwayi ntibashobora gutandukanya amabara atandukanye.

Mugihe habaye ibikorwa byinshi byingirakamaro mugutezimbere imiti idahwitse yubuhumyi bwamabara hashingiwe kumihanda myinshi yubuvuzi kuriyi miterere, ihinduka ryimibereho rikomeje kuba impaka zifunguye. mudasobwa n'ibikoresho bigendanwa ni ingingo zikubiye mubushakashatsi bwabanje.
Ibirahuri byahinduwe bifite amabara yungurura byakorewe ubushakashatsi bwimbitse kandi bigaragara ko biboneka cyane kubuvuzi bwa CVD.
Mugihe ibyo birahure bigenda byongera imyumvire yibara kubantu bafite ubumuga bwo kutabona, bafite ibibi nkibiciro bihanitse, uburemere buremereye nubwinshi, no kutagira aho bihurira nibindi birahure bikosora.
Kugira ngo CVD ikosorwe, hashyizweho ubushakashatsi bwifashishije pigment ya chimique, metasurface ya plasmonic, na plasmonic nanoscale.
Nyamara, utwo tuntu two guhuza duhura nimbogamizi nyinshi, zirimo kutabangikanya ibinyabuzima, imikoreshereze mike, umutekano muke, igiciro kinini, hamwe nibikorwa bigoye.
Igikorwa kiriho kirerekana ibice bibiri-biocompatible na elastique plasmonic contact lens ishingiye kuri polydimethylsiloxane (PDMS) kugirango ikosore ubuhumyi bwamabara, hibandwa cyane cyane kubuhumyi bwamabara akunze kugaragara, guhumeka amabara ya deuterochromatic (umutuku- icyatsi).
PDMS ni biocompatible, flexible and transparent polymer ishobora gukoreshwa mugukora lens ya contact.Iyi ngingo itagira ingaruka kandi yibinyabuzima yasanze ikoreshwa muburyo butandukanye mubinyabuzima, ubuvuzi nubuvuzi.

Muri uyu murimo, 2D ya biocompatible na elastique plasmonic contact lens yakozwe na PDMS, ihendutse kandi yoroshye gushushanya, yakozwe hifashishijwe uburyo bworoheje bwa nanoscale lithographie, hanyuma hakosorwa ubugororangingo bwa deuteron.
Lens ikozwe muri PDMS, hypoallergenic, idafite ibyago, elastike kandi ikorera mu mucyo.Iyi lens ya contact ya plasmonic, ishingiye kuri phenomenon ya plasmonic surface lattice resonance (SLR), irashobora gukoreshwa nkayunguruzo rwamabara meza mugukosora ibintu bidasanzwe bya deuteron.
Lens ziteganijwe zifite ibintu byiza nko kuramba, biocompatibilité na elastique, bigatuma bikwiranye no gukosora ibara rihumye.
Inshingano: Ibitekerezo byavuzwe hano ni ibyumwanditsi mubushobozi bwabo kandi ntabwo byanze bikunze byerekana ibitekerezo bya AZoM.com Limited T / A AZoNetwork, nyiri uruganda nuwukoresha kururu rubuga. Uku kwamagana kugizwe nibice bigize amategeko n'amabwiriza ya gukoresha uru rubuga.
