Ocwaningweni lwakamuva olushicilelwe kumagazini we-Scientific Reports, amalensi okuxhumana e-plasmonic anezinhlangothi ezimbili enziwe nge-polydimethylsiloxane (PDMS).
Ucwaningo: Amalensi okuxhumana e-plasma anezinhlangothi ezimbili ukuze kulungiswe ubumpumputhe bemibala.
Lapha, idizayini eyisisekelo engabizi yokulungisa ubumpumputhe bombala obomvu-oluhlaza yaklanywa futhi yahlolwa ngokusekelwe ku-nanolithography ethambile.
Ukubona kombala womuntu kususelwa kumaseli e-photoreceptor amise okwekhoni amathathu, amakhoni amade (L), aphakathi (M), namafushane (S), abalulekile ekuboneni amathoni abomvu, aluhlaza, aluhlaza okwesibhakabhaka, anokuzwela okubonakalayo okungama-430. , 530 kanye ne-560 nm, ngokulandelana.
Ubumpumputhe bemibala, okwaziwa nangokuthi ukuntula ukubona umbala (i-CVD), isifo samehlo esivimbela ukutholwa nokuchazwa kwemibala ehlukene ngamaseli amathathu e-photoreceptor asebenza ngokubona okuvamile futhi asebenze ngokuya ngokuzwela kwawo okubonakalayo okukhulu.Lesi sifo samehlo, esingase kube nomthelela noma ufuzo, kubangelwa ukulahlekelwa noma iphutha kumaseli e-cone photoreceptor.
Umdwebo oyisikimu wenqubo yokwenziwa kwelensi ehlongozwayo esekwe ku-PDMS, (b) izithombe zelensi eyenziwe yakhiwe ku-PDMS, kanye (c) nokucwiliswa ngelensi esekwe ku-PDMS ku-HAuCl4 3H2O isixazululo segolide sezikhathi ezihlukene zokufukamela .© Roostaei, N. no-Hamidi, SM (2022)
I-Dichroism yenzeka lapho enye yezinhlobo ezintathu zamaseli e-cone photoreceptor ingekho ngokuphelele;futhi ihlukaniswa njenge-proteophthalmia (awekho ama-photoreceptors e-cone ebomvu), i-deuteranopia (awekho ama-photoreceptors ekhoni eluhlaza), noma ubumpumputhe be-trichromatic Color (ukuntuleka kwama-photoreceptors wekhoni eluhlaza okwesibhakabhaka).
I-Monochromaticity, indlela engavamile kakhulu yokungaboni umbala, ibonakala ngokungabi bikho okungenani izinhlobo ezimbili zamaseli e-cone photoreceptor.
I-Monochromatics i-colorblind ngokuphelele (i-colorblind) noma inama-photoreceptors e-cone eluhlaza okwesibhakabhaka kuphela.Uhlobo lwesithathu lwe-trichromacy engavamile lwenzeka uma enye yezinhlobo zamaseli e-cone photoreceptor ingasebenzi.
I-Aberrant trichromacy ihlukaniswe yaba izinhlobo ezintathu ngokusekelwe ohlotsheni lwesici se-cone photoreceptor: i-deuteranomaly (ama-photoreceptors ekhoni eluhlaza angenasici), i-protanomaly (ama-photoreceptors e-cone ebomvu anesici), kanye ne-tritanomaly (ama-photoreceptors ekhoni eluhlaza okwesibhakabhaka anesici) amaseli e-photoreceptor).
Ama-Protans (i-protanomaly ne-protanopia) nama-deutans (i-deuteranomaly ne-deuteranopia), eyaziwa ngokuthi i-protanopia, ayizinhlobo ezijwayelekile kakhulu zokungaboni umbala.
I-Protanomaly, iziqongo zokuzwela kwe-spectral zamaseli ekhoni abomvu ashintshwa ngokuluhlaza okwesibhakabhaka, kuyilapho ubukhulu bokuzwela bamaseli ekhoni eluhlaza bushintshwa ngokubomvu.Ngenxa yokungezwani kokubukeka okungqubuzanayo kwama-photoreceptor aluhlaza nabomvu, iziguli azikwazi ukuhlukanisa imibala ehlukene.
Umdwebo oyisikimu wenqubo yokwenziwa kwelensi yokuxhumana ye-plasmonic ye-2D ehlongozwayo esekelwe ku-PDMS, kanye (b) nesithombe sangempela se-2D eguquguqukayo yelensi yokuxhumana ye-plasmonic.© Roostaei, N. and Hamidi, SM (2022)
Nakuba kube nomsebenzi omningi obalulekile ekuthuthukiseni ukwelashwa okungenangqondo kobumpumputhe bemibala ngokusekelwe ezindleleni ezimbalwa zezokwelapha zalesi simo, ukulungiswa okukhulu kwendlela yokuphila kuseyimpikiswano evulekile. amakhompyutha namadivayisi eselula yizihloko ezivezwe ocwaningweni lwangaphambilini.
Izibuko ezinemibala enokuhlunga zicutshungulwe kahle futhi zibonakala zitholakala kabanzi ukuze zelashwe i-CVD.
Nakuba lezi zibuko ziphumelela ekwandiseni umbono wombala kubantu abangaboni umbala, banezinkinga ezifana nenani eliphezulu, isisindo esinzima kanye nenqwaba, nokuntuleka kokuhlanganiswa nezinye izibuko zokulungisa.
Ukuze kulungiswe i-CVD, amalensi okuxhumana athuthukiswe kusetshenziswa i-pigment yamakhemikhali, i-plasmonic metasurfaces, nezinhlayiya ze-plasmonic nanoscale zisanda kuphenywa.
Kodwa-ke, lawa ma-contact lens abhekana nezingqinamba eziningi, okuhlanganisa ukuntula kwe-biocompatibility, ukusetshenziswa okulinganiselwe, ukuzinza okubi, intengo ephezulu, nezinqubo zokukhiqiza eziyinkimbinkimbi.
Umsebenzi wamanje uphakamisa amalensi okuxhumana e-biocompatible anezinhlangothi ezimbili kanye nokunwebeka kwe-plasmonic asekelwe ku-polydimethylsiloxane (PDMS) ukuze kulungiswe ubumpumputhe bombala, kugcizelelwe ngokukhethekile ubumpumputhe bombala obuvame kakhulu, i-deuterochromatic anomaly (bomvu-luhlaza) ubumpumputhe bombala.
I-PDMS i-biocompatible, flexible and transparent polymer engasetshenziswa ukwenza amalensi okuxhumana.Le nto engenabungozi futhi ehambisana ne-biocompatible ithole ukusetshenziswa okuhlukahlukene embonini yebhayoloji, yezokwelapha kanye neyamakhemikhali.
Kulo msebenzi, amalensi okuxhumana e-2D biocompatible kanye ne-elastic plasmonic enziwe nge-PDMS, angabizi futhi aqonde ukuklama, athuthukiswa kusetshenziswa indlela ye-nanoscale lithography emnene, futhi ukulungiswa kwe-deuteron kwahlolwa.
Amalensi enziwe nge-PDMS, i-hypoallergenic, engeyona ingozi, i-elastic and transparent polymer.Le lens yokuxhumana ye-plasmonic, esekelwe kwinto ye-plasmonic surface lattice resonance (SLR), ingasetshenziswa njengesihlungi sombala esihle kakhulu sokulungisa i-deuteron anomalies.
Amalensi ahlongozwayo anezinto ezinhle ezinjengokuqina, i-biocompatibility kanye nokunwebeka, okuwenza afanelekele izinhlelo zokusebenza zokulungisa ubumpumputhe bombala.
