Abahanga mu bya siyansi bashyizeho urubuga rwo guteranya ibigize nanosised ibice bifatika, cyangwa "nano-ibintu," byubwoko butandukanye - incuro cyangwa kama - muburyo bwa 3-D. Nubwo kwiteranya (SA) byakoreshejwe neza mugutegura Nanomarial yubusa bwoko bwinshi, inzira yabaye sisitemu yihariye, ikabyara inzego zitandukanye zishingiye kumiterere yimbere yibikoresho byibikoresho byibikoresho byibikoresho. Nkuko byatangajwe mu mpapuro zasohowe uyu munsi mu bikoresho bya kamere, urubuga rwabadahwitse rwa ADNA rushobora gukoreshwa mu buryo bumwe bwo gutegura ibikoresho bimwe na kimwe cya mbere kuri Nanoscale (miliyari), imiti ye igaragara.
Umuyobozi wa Elegiya Oleg, ati: "Imwe mu mpamvu zikomeye zaba Nanomarial zituma SA atari tekinike ya Nanomaterial Laboratoire - na profeseri yubuhanga bwibimami hamwe na physics hamwe nibikoresho bya siyanse kuri Columbia Ubwubatsi. Ati: "Hano, twaretse inzira ya SA haturuka ku mitungo y'ibikoresho dushushanya amakadiri ya polyagedral ya ADN ishobora kwangiza ibintu bitandukanye by'ibihanga cyangwa kama, harimo na Brominonduct, ndetse na poroterume."
Abahanga bakoranye amakadiri ya synthetic adna muburyo bwa cube, Octahedron, na Tetrahedron. Imbere mu bikadiri ni ADN "amaboko" ko nano-ibintu byonyine bifite aho byuzuzanya bishobora guhambira. Izi jambo ryibikoresho - Kwishyira hamwe kwa ADN na Nano-ikintu - ni ibice byubaka macroscale 3-d irashobora gutangwa. Amakadiri ahurirana tutitaye kubwoko bwa Nano-ikintu kiri imbere (cyangwa ntabwo) dukurikije urutonde rwuzuzanya rwasimbujwe hamwe na vertike zabo. Ukurikije imiterere yabo, amakadiri afite umubare utandukanye wa vertike bityo ukore neza rwose. Ibintu byose nano-ibintu byakiriwe imbere muri frame bifata iyo miterere yihariye.
Kugaragaza uburyo bwabo bwo guterana, abahanga bahisemo ibyuma (zahabu) na semiconducting (cadmium selenicles hamwe na poroteyine ya bagiteri (stroptavitique) nkuko ibintu byateganijwe kandi kama-kama bigomba gushyirwa imbere muri ADN. Ubwa mbere, bemeje ubusugire bwamadiri ya ADN no gushiraho amajwi yibintu batekereza hamwe na microscopes ya CFN electros hamwe nikigo cya Van Andel, gifite ibikoresho bikorera kuri clogenic ubushyuhe bwibinyabuzima. Bahise bagerageza imiterere ya 3-D Lattice kuri X-Ray Gukwirakwiza hamwe nibikoresho bigoye bikwirakwiza ibiti byigihugu cyigihugu II (NSLS-II). Columbia Ubwubatsi Bykhovsky Porofeseri wo mu Buhanga bw'imiti Satat Kumar n'itsinda rye ryaratagaho imitunganyirize ya Lattesimentitse (bishingiye kuri X-Ray.
Kumar yasobanuye ati: "Izi vox zidushoboza gutangira gukoresha ibitekerezo bikomoka kuri atome (na molekile) na kaburimbo iyo ari yo, na Prisstals barimo, n'imbure kuri sisitemu ishishikajwe na Nanoscale."
Abanyeshuri ba Gang muri Columbiya bahise bagaragaza uburyo urubuga rwiteraniro rushobora gukoreshwa mugutwara imitunganyirize yibikoresho bibiri bitandukanye hamwe nibikorwa byimiti n optique. Mu rubanza rumwe, bateranya imirongo ibiri, batera 3-D inzara ifite ubucucike bwo gupakira. Nubwo ubwenge bwakomeje guhinduka ibintu bihinduka, bagaragaje ubwiyongere bune mubikorwa byiziritse. Aba "NajoreaCors" barashobora gukoreshwa mugukoresha ibiganiro bya Cascade no gushoboza guhimba ibikoresho bifatika. Kubijyanye no kwerekana ibintu bya optique, bavanze amabara abiri atandukanye ya quanim utudomo - ntoya zikoreshwa mugukora televiziyo yuzuye ibara ryuzuye kandi ryumucyo. Amashusho yafashwe na microscope ya fluorescence yerekanaga ko lattice yashizwemo ibara ryuzuye munsi yumupaka itandukanye (uburebure bwamazuru) bwumucyo; Uyu mutungo urashobora kwemerera iterambere ryinshi ryiterambere muburyo butandukanye bwo kwerekana no gutunganya itumanaho.
Gang yagize ati: "Tugomba gutekereza ku buryo ibikoresho bishobora gushingwa nuburyo bukora." "Gutanga ibintu ntibishobora kuba ngombwa; Gupakira gusa ibikoresho bihari muburyo bushya bishobora kuzamura imitungo yabo. Birashoboka, Ihuriro ryacu rishobora kuba ikoranabuhanga ryiza 'rirenze 3-D Gucapa Byakozwe' kugirango ugenzure ibikoresho umunzani muto kandi hamwe nibikoresho bitandukanye nibikorwa byateguwe. Ukoresheje inzira imwe kugirango ukore inkweto 3-d uhereye kuri Nano-ibintu byinshi byimibare itandukanye, guhuza ibyo byaba bitareba ubundi bidahuye, birashobora kuvugurura Nanomanike. "
Ibikoresho byatanzwe na Doe / Laboratwari yigihugu ya Brookhavery. Icyitonderwa: Ibirimo birashobora guhinduka muburyo nuburebure.

Tubwire icyo utekereza kuri siyansedaily - twishimiye ibitekerezo byiza kandi bibi. Ufite ibibazo ukoresheje urubuga? Ibibazo?
