Kuphononongo lwakutsha nje olupapashwe kwijenali yeeNgxelo zeSayensi, iilensi zonxibelelwano ezine-dimensional biocompatible kunye ne-elastic plasmonic zenziwe kusetyenziswa i-polydimethylsiloxane (PDMS).
UPhando: Iilensi zoqhagamshelwano zeplasma ezinomacala amabini zilungele ukulungiswa kobumfama bombala.
Apha, uyilo olusisiseko olungabizi kakhulu lokulungisa ubumfama bombala obomvu-oluhlaza lwenzelwe kwaye lwavavanywa ngokusekwe kwi-nanolithography ethambileyo.
Umbono wombala womntu uthatyathwe kwiiseli zefotoreceptor ezimilise okwekhowuni ezintathu, ezinde (L), eziphakathi (M), nezimfutshane (S) iicones, eziyimfuneko ekuboneni iithowuni ezibomvu, eziluhlaza, nebhlowu, ezinobuntununtunu obungama-430. , 530 kunye ne-560 nm, ngokulandelanayo.
Ubumfama bombala, obukwabizwa ngokuba yi-colour vision deficiency (CVD), sisifo samehlo esithintela ukubonwa kunye nokutolikwa kwemibala eyahlukeneyo ngeeseli ezintathu ze-photoreceptor ezisebenza ngokubona okuqhelekileyo kwaye zisebenze ngokobuntununtunu be-spectral maxima. ukuba ngqongqo okanye ufuzo, kubangelwa ukulahlekelwa okanye isiphene kwiiseli ze-cone photoreceptor.

I-Dichroism yenzeka xa enye yeentlobo ezintathu zeeseli ze-cone photoreceptor ingekho ngokupheleleyo;kwaye ihlelwa njenge-proteophthalmia (akukho zi-photoreceptors zekhowuni ebomvu), i-deuteranopia (akukho fotoreceptors yekowuni eluhlaza), okanye i-trichromatic Ubumfama bombala (ukunqongophala kweefotoreceptors zekowuni eluhlaza okwesibhakabhaka).
I-Monochromaticity, eyona ndlela incinci yokumfameka kombala, ibonakala ngokungabikho kweentlobo ezimbini zeeseli ze-cone photoreceptor.
Monochromatics mhlawumbi colorblind ngokupheleleyo (colorblind) okanye kuphela blue cone photoreceptors.Uhlobo lwesithathu engaqhelekanga trichromacy kwenzeka ukuba enye yekowuni photoreceptor iintlobo iiseli ukungasebenzi.
I-Aberrant trichromacy yahlulwe yazintlobo ezintathu ngokusekelwe kuhlobo lwesiphene se-cone photoreceptor: i-deuteranomaly (i-photoreceptors ye-cone eluhlaza eneziphene), i-protanomaly (i-photoreceptors ye-cone ebomvu eneziphene), kunye ne-tritanomaly (i-photoreceptors ye-cone eneziphene) iiseli ze-photoreceptor).
Iiprotans (i-protanomaly kunye ne-protanopia) kunye ne-deutans (i-deuteranomaly kunye ne-deuteranopia), eyaziwa njenge-protanopia, zezona ntlobo ziqhelekileyo zokungaboni ngemibala.
I-Protanomaly, iincopho ze-spectral sensitivity yeeseli ezibomvu ze-cone zi-blue-shifted, ngelixa i-sensitivity maxima yeeseli ze-cone eziluhlaza ziguqulwa zibomvu.Ngenxa ye-spectral sensitivities eziphikisanayo ze-photoreceptors eziluhlaza kunye nebomvu, izigulane azikwazi ukwahlula imibala eyahlukeneyo.

Ngelixa bekukho umsebenzi omninzi oxabisekileyo ekuphuhliseni unyango olungenabutyhakala lobumfama bombala olusekelwe kwiindlela ezininzi zonyango lwale meko, uhlengahlengiso oluphambili lwendlela yokuphila luhlala luyingxoxo evulekileyo. Unyango lweGene, iiglasi ezinemibala, iilensi, izihluzi zamehlo, iiglasi ze-optoelectronic, kunye nezincedisi iikhomputha kunye nezixhobo eziphathwayo zizihloko ezigutyungelwe kuphando lwangaphambili.
Iiglasi ezifakwe umbala ezinezihluzi ezinemibala ziye zaphandwa ngokucokisekileyo kwaye zibonakala zifumaneka ngokubanzi kunyango lwe-CVD.
Nangona ezi glasi ziphumelele ekwandiseni ukubonakala kombala kubantu abangaboniyo, banezinto ezingalunganga ezifana nexabiso eliphezulu, ubunzima obunzima kunye nobuninzi, kunye nokungabikho kokudibanisa nezinye iiglasi zokulungisa.
Ukulungiswa kwe-CVD, iilensi zoqhagamshelwano eziphuhliswe kusetyenziswa i-pigments yekhemikhali, i-plasmonic metasurfaces, kunye ne-plasmonic nanoscale particles zisanda kuphandwa.
Nangona kunjalo, ezi lens zoqhagamshelwano zijongene nemiqobo emininzi, kubandakanywa ukunqongophala kwe-biocompatibility, ukusetyenziswa okulinganiselweyo, ukuzinza okubi, ixabiso eliphezulu, kunye neenkqubo zokuvelisa eziyinkimbinkimbi.
Umsebenzi okhoyo uphakamisa iilensi zoqhagamshelwano ezine-dimensional biocompatible kunye ne-elastic plasmonic esekwe kwi-polydimethylsiloxane (PDMS) yokulungiswa kobumfama bombala, kugxininiswa ngokukodwa kobona bumfama buxhaphakileyo bombala, i-deuterochromatic anomaly (bomvu-luhlaza) ubumfama bombala.
I-PDMS yi-polymer e-biocompatible, eguquguqukayo kunye ne-transparent engasetyenziselwa ukwenza iilensi zoqhagamshelwano.Le nto engenabungozi kunye ne-biocompatible ifumene usetyenziso oluhlukeneyo kwi-biological, medical and chemical industry.
Kulo msebenzi, i-2D biocompatible kunye ne-elastic plasmonic contact lens ezenziwe nge-PDMS, ezingabizi kwaye zithe ngqo ukuyila, zaphuhliswa kusetyenziswa indlela ye-nanoscale lithography elula, kwaye ukulungiswa kwe-deuteron kwavavanywa.
Iilensi zenziwe kwi-PDMS, i-hypoallergenic, i-polymer enobungozi, i-elastic kunye ne-transparent.Le lens yoqhagamshelwano ye-plasmonic, esekelwe kwinto ye-plasmonic surface lattice resonance (SLR), inokusetyenziswa njengesihluzo sombala obalaseleyo wokulungisa i-deuteron anomalies.
Iilensi ezicetywayo zineempawu ezintle ezifana nokuqina, ukuhambelana kwe-biocompatibility kunye no-elasticity, okwenza ukuba zilungele izicelo zokulungiswa kombala.
