Muchidzidzo chechangobva kuitika chakabudiswa mupepanhau Scientific Reports, maviri-dimensional biocompatible uye elastic plasmonic contact lenses akagadzirwa achishandisa polydimethylsiloxane (PDMS).
Tsvagiridzo: Maviri-dimensional biocompatible plasma yekuonana lenses yekururamisa upofu hwemavara.
Pano, yakachipa yakakosha dhizaini yekugadzirisa tsvuku-yegirinhi ruvara upofu yakagadzirwa uye yakaedzwa zvichibva pane yakapfava nanolithography.
Maonero eruvara rwemunhu anotorwa kubva mumasero matatu akaita makoni, akareba (L), epakati (M), uye mapfupi (S) makoni, ayo akakosha pakuona matoni matsvuku, egirinhi, uye ebhuruu, ane spectral sensitivity inodarika 430. , 530 uye 560 nm, zvichiteerana.
Colour blindness, inozivikanwawo seColour vision deficiency (CVD), chirwere chemaziso chinotadzisa kuonekwa nekududzirwa kwemavara akasiyana nemasero matatu ephotoreceptor anoshanda mukuona kwemazuva ese uye anoshanda zvinoenderana ne spectral sensitivity maxima.Ichi chirwere chemaziso, chinogona kuve constrictive kana genetic, kunokonzerwa nekurasikirwa kana kukanganisa mucone photoreceptor masero.

Dichroism inoitika kana imwe yemhando nhatu dzekoni photoreceptor masero isipo zvachose;uye inorondedzerwa seproteophthalmia (hapana tsvuku yekoni photoreceptors), deuteranopia (hapana green cone photoreceptors), kana trichromatic Rudzi upofu (kushaya blue cone photoreceptors).
Monochromaticity, iyo isinganyanyozivikanwa yehupofu hwemavara, inoratidzirwa nekusavapo kweanokwana maviri cone photoreceptor cell marudzi.
Monochromatics angave akazara colorblind (colorblind) kana kuti ane blue cone photoreceptors.Rudzi rwechitatu rwe abnormal trichromacy runoitika kana imwe yekoni photoreceptor mhando dzemasero dzikatadza kushanda.
Aberrant trichromacy yakakamurwa kuita mhando nhatu zvichienderana nerudzi rwekoni photoreceptor defect: deuteranomaly (yakakanganiswa yegirini koni photoreceptors), protanomaly (yakakanganisika red cone photoreceptors), uye tritanomaly (defective blue cone photoreceptors) photoreceptor masero).
MaProtans (protanomaly and protanopia) uye deutans (deuteranomaly uye deuteranopia), anowanzozivikanwa seprotanopia, ndiwo anonyanya kuzivikanwa marudzi ehupofu hwemavara.
Protanomaly, iyo spectral senitivity peaks ye red cone cells iblue-shifted, nepo senitivity maxima yegreen cone cells yakatsvuka-yakachinjwa.Nekuda kwekukakavadzana kwekunzwa kwekunzwa kwegirinhi uye tsvuku photoreceptors, varwere havagoni kusiyanisa mavara akasiyana.

Kunyange zvazvo kwave kune basa rakawanda rakakosha mukugadzira marapirwo eupenzi ekupofomara kwemavara kunobva kune akati wandei nzira dzekurapa dzechirwere ichi, gadziriso huru yemararamiro inoramba iri gakava rakavhurika.Gene therapy, tinted glasses, lenzi, optical filters, optoelectronic glasses, and enhancements on. makomputa uye nharembozha misoro yakafukidzwa muongororo yapfuura.
Magirazi akatsvuka ane mafirita eruvara akanyatso tsvagurudzwa uye anoita seanowanikwa zvakanyanya pakurapwa kweCVD.
Kunyange zvazvo magirazi aya achibudirira mukuwedzera kwemavara ekuona kwevanhu vane ruvara rwemavara, vane zvisingabatsiri zvakadai semutengo wakakwirira, uremu hunorema uye huwandu, uye kusava nekubatanidzwa nemamwe magirazi ekugadzirisa.
Kugadziriswa kweCVD, malenzi ekusangana akagadzirwa achishandisa makemikari pigments, plasmonic metasurfaces, uye plasmonic nanoscale particles ichangobva kuongororwa.
Nekudaro, aya malenzi ekusangana anotarisana nezvipingamupinyi zvakawanda, zvinosanganisira kushomeka kwebiocompatibility, kushandiswa kushoma, kusagadzikana kwakashata, mutengo wepamusoro, uye maitiro akaomarara ekugadzira.
Iri basa riripo rinokurudzira maviri-dimensional biocompatible uye elastic plasmonic contact lenses akavakirwa pa polydimethylsiloxane (PDMS) yekururamisa upofu hwemavara, nekusimbisa kwakanyanya pahunowanzo hupofu hwemavara, deuterochromatic anomaly (red-girini) upofu hwemavara.
PDMS inonzi biocompatible, flexible and transparent polymer inogona kushandiswa kugadzira contact lenses.Ichi chinhu chisingakuvadzi uye chinopindirana chebiocompatible chakawana kushandiswa kwakasiyana-siyana mubiology, mishonga uye makemikari industries.
Mune basa iri, 2D biocompatible uye elastic plasmonic contact lenses yakagadzirwa nePDMS, iyo isingadhuri uye yakatwasuka kugadzira, yakagadziridzwa uchishandisa mild nanoscale lithography nzira, uye deuteron kururamisa kwakaedzwa.
Malenzi akagadzirwa kubva kuPDMS, hypoallergenic, isiri-hazardous, elastic and transparent polymer.Iyi plasmonic contact lens, yakavakirwa pachiitiko cheplasmonic surface lattice resonance (SLR), inogona kushandiswa seyakanakisa ruvara sefa yekugadzirisa deuteron anomalies.
Malenzi akarongwa ane zvinhu zvakanaka zvakaita sekugara, biocompatibility uye elasticity, zvichiita kuti akwanise kugadziridza upofu hwemavara.
