Saynisyahannadu waxay soo saareen goob lagu ururiyo qaybo ka mid ah qaybo ka mid ah, ama "nano-ashyaa," noocyo aad u kala duwan - INRANICENIC ama mid dabiici ah - oo loo maro dhismayaasha 3-D ee la doonayo. " Sida lagu soo sheegay warqad warqad ah oo maanta lagu daabacay agabyada dabiiciga ah, waxaa lagu dabaqi karaa madasha nawaayadda cusub ee DNA-DNA-da isla siyaabo yar oo loo qoray (bilyanths oo mitir ah), halkaas oo ah in kiimikooyin, iyo hanti kale.
"Mid ka mid ah sababaha ugu weyn ee aan SA uusan ahayn farsamo ku saabsan codsiyada wax ku oolka ah waa in si isku mid ah looguma daweyn karo kuwa 3-D ee ah nanoomates-ka nanomatates (CFN) - Xafiiska Waaxda Tamarta ee Mareykanka (DOE) Xarunta Isticmaalaha ee Brookhaven Shaybaarka qaranka - oo ah borofisar ku saabsan injineeriyadda kiimikada ah iyo fisikikada fiisigiska iyo agabyada alaabada ee Columbia Injineerinka Columbia. "Halkan, waxaan ku qiimeynay howsha SA ee guryaha anigoo qaabeeya xargaha adag ee polyhedral-ka ah ee ku saabsanaan badan oo ka tariir karta.
Saynisyahanada ayaa injineer ku ah qaab-dhismeedka DNA-ga ee DNA qaab ahaan qaabka cube, octakeedron, iyo tetradisdron. Gudaha gogosha waa DNA "hubka" oo keliya nano-sheyga oo keliya taxanaha isku xigxiga DNA-da ee la dhameystiri karo. Voxels-kaan - is dhexgalka loo yaqaan 'DNA-ga' iyo nano-sedex - waa dhismayaasha dhismayaasha ee qaab dhismeedka 3-D ee MACroscale. Xargaha ayaa isku xira midba midka kale iyadoon loo eegin nooca nano-shay-shay-shay gudaha ah (ama aan ahayn) iyadoo loo eegayo taxanaha isugeynta ah ee ay ku yaalliin hareerahooda. Waxay kuxirantahay qaabkooda, xirmooyinku waxay leeyihiin tiro ka duwan xariiqyo oo ay sidaas oo kale u sameeyaan qaabdhismeedyo kala duwan. Wax kasta oo nano-ashyaa lagu soo bandhigo gudaha xirmooyinka ayaa ku dhaca qaab dhismeedkaas gaarka ah.
Si loo muujiyo qaabkooda goluhu, saynisyahanada macquulka ah ee loo xushay (dahab) iyo semicouction (Selfium Senaparticles) nanoparticles iyo borotiin bakteeriyada ah (streptavilin) inay yihiin enno-abbaaraha nano-walxaha lagu ridayo gudaha DNA-ga. Marka hore, waxay xaqiijiyeen daacadnimada xildhibaanka DNA-da iyo samaynta weelka archos-ka ee elektaroonigga ah ee elektaroonigga ah ee elektaroonigga ah ee 'Van And And And And And And And And And And And And And And And And And And And And And And And And And And And And And And Andel' oo ku shaqeeya heerkulka macdanta ee tusaalayaasha bayoolojiyeed. Waxay markaa ka sara kiciyaan qaabdhismeedka 3-D-ga ee isku-dhafka ah ee isku-darka leh ee isku-dhafka ah ee isku-dhafka ah ee isku-dhafan Injineeriyada Columbia ee Injineerinka Bykhovsky Profession Sanat Kumar iyo kooxdiisu waxay sameysay qaab dhismeedka khaaska ah ee la muujiyey in si qunyar socodka ah ay yihiin kuwa ugu xasilloon ee ay ka hadli karaan maahmaahda.
"Voxels-kaan waxay noo oggolaadaan inaan bilowno fikradaha laga soo qaatay atomyada (iyo molecules) iyo crystals) iyo cryaraallada ay sameeyaan, iyo dekada aqoontan iyo keydka macluumaadka ah ee loo xiiseeyo Nanoscale," ayuu yiri Kumar.
Ardayda baandada ee Columbia ayaa markaa muujinaya sida loo adeegsado hay'adda Golaha loo adeegsan karo in lagu kaxeeyo ururka laba nooc oo ah agabyo kala duwan oo leh howlo kiimikaad iyo kuwa indhaha ah. Hal kiis, waxay isu soo urursadeen laba enzymes, oo abuuraya 3-D u diyaarsanaanta cufnaanta sare ee xirxiran. In kasta oo enzymes-ka aan si kibis u laheyn, waxay muujiyeen in afar geesood kor u kaca waxqabadka enzymatic. "Nanoreates-ka" waxaa loo isticmaali karaa in lagu maareeyo falcelinta cascade ah oo ay u saamaxdo xaraashka qalabka kiimikada. Mudaaharaadyada indhaha ee indhaha, waxay isku qasmeen laba midab oo kala duwan oo dhibco dhibco ah - nanocrystalstal yar yar oo loo isticmaalay in lagu sameeyo bandhigyo telefishan oo ay ku jiraan fadhiyada midabka leh iyo iftiinka. Sawirada lagu qabtay microscope fallaaraha ah ayaa muujisay in jilitaanka la sameeyay ee la sameeyay oo lagu hayo midab midab leh oo ka hooseeya xadka kala-goysyada ah (mawjadda) iftiinka; Hantidan ayaa u oggolaaneysa hagaajinta qaraar weyn ee soo bandhigida kala duwan iyo tikniyoolajiyadda isgaarsiinta ee indhaha.
"Waxaan u baahanahay inaan dib uga fikirno sida qalabka loo abuuri karo iyo sida ay u shaqeeyaan," ayuu yiri burcad. "Dib-u-habeynta maaddada looma baahna; in si fudud loo soo qaado agabyada jira siyaabo kala duwan oo loo yaqaan 'tekniyoolajiyada' '' wax ka baxsan xargaha loo yaqaan '3-D-ka' ee loo baahan yahay in si kale loo tixgeliyo in kale oo loo qaddariyo inay iswaafaqsan yihiin, way isbedelayaan Nanomanukeenin. "
Alaabada ay soo bandhigaan Doe / Shaybaarka Qaranka ee Brookhaven. Xusuusin: Waxyaabaha laga yaabo ayaa laga yaabaa in loo saxo qaabka iyo dhererka.
