Genetic code rau sau npe cov khoom thiab cov neeg ua txhaum cai
Barcodes thiab QR codes siv los sau txhua yam ntawm T-shirts hauv khw muag khaub ncaws mus rau lub tsheb cav yuav sai sai no hloov los ntawm DNA-raws li daim ntawv lo uas tsis pom ntawm qhov muag liab qab thiab tsis tuaj yeem muab tshem tawm lossis cuav.
Hauv ib tsab xov xwm luam tawm hauv Nature Communications, cov kws tshawb fawb los ntawm University of Washington thiab Microsoft tau nthuav tawm molecular labeling systemhu ua porcupine. Raws li cov kws tshawb fawb. Nws yuav nyuaj rau cov neeg txhaum cai los txheeb xyuas thiab tshem tawm lossis hloov DNA tag Cov khoom muaj txiaj ntsig lossis cov khoom tsis zoo xws li cov ntawv pov npav, cov duab kos duab lossis cov ntaub ntawv cais.
Tsis tas li ntawd, lawv thov tias lawv cov kev daws teeb meem, tsis zoo li feem ntau lwm cov cim, yog tus nqi zoo. "Kev siv DNA los sau cov khoom tau nyuaj yav dhau los vim kev sau ntawv thiab nyeem ntawv nws feem ntau kim heev thiab siv sijhawm, thiab yuav tsum tau siv cov khoom siv lab kim," tus kws tshawb fawb tus thawj coj ntawm University of Washington kawm tiav cov tub ntxhais kawm hais rau AFP. Katy Doroshchak.
Porcupine tso cai rau koj los tsim DNA tawg ua ntejuas cov neeg siv yog pub dawb los tsim cov cim npe tshiab. Porcupine labeling scheme yog ua raws li kev siv cov txheej txheem DNA hu ua molecular khoom, lossis "molbits" luv luv, raws li tsab ntawv tshaj tawm los ntawm University of Washington.
Doroschak piav qhia tias "Yuav kom encode tus cim, peb muab txhua qhov digital me ntsis nrog molbit." "Yog tias tus lej digital yog 1, peb ntxiv nws rau lub cim, thiab yog tias nws yog 0, peb tsis quav ntsej nws. Qhov no yog ua raws li kev ziab ntawm DNA strands kom txog thaum lawv npaj txhij rau kev txiav txim siab tom ntej. Thaum cov khoom tau sau npe, nws tuaj yeem xa lossis khaws cia. " Thaum ib tug neeg xav nyeem cov cim, moisturizing thiab nyeem nrog nanoporous sequencer, tus nyeem ntawv DNA me dua li iPhone.
Tsis zoo li cov khoom cim uas twb muaj lawm, ntxiv rau kev tiv thaiv, DNA-raws li txoj kev tseem tuaj yeem kos cov khoom uas yuav nyuaj rau barcode.
"Nws tsis tuaj yeem kos paj rwb lossis lwm yam textiles nrog cov qauv zoo li RFID tag thiab, tab sis koj tuaj yeem siv cov huab-nyeem tau DNA-raws li tus cim, "Doroshchak ntseeg. "Qhov no tuaj yeem siv tau rau hauv cov khoom siv sib txuas uas qhov kev taug qab yog qhov tseem ceeb los tswj cov khoom muaj nqis."
DNA cim qhov no tsis yog lub tswv yim tshiab, tab sis txog tam sim no nws tau paub tsuas yog los ntawm kev ua haujlwm ntawm tub ceev xwm tawm tsam cov neeg ua phem. Muaj cov khoom zoo li Xaiv DNA Tshuaj tsuag, siv los tiv thaiv thiab tiv thaiv tus kheej tawm tsam thiab lwm yam kev ua txhaum cai. Qhov no yog qhov muaj txiaj ntsig zoo nyob rau hauv rooj plaub ntawm kev ua txhaum cai los ntawm cov neeg ua txhaum cai ntawm mopeds thiab maus taus. Lub aerosol cim lub tsheb, khaub ncaws thiab tawv nqaij ntawm txhua tus neeg tsav tsheb thiab cov neeg caij tsheb nrog cov cim cim tshwj xeeb tab sis pom tsis pom DNA uas muab cov pov thawj pov thawj txuas rau cov neeg ua txhaum cai.
Lwm cov tshuaj hu ua DNA Tus Saib Xyuas, siv tsis raug mob rau kev noj qab haus huv, cim coded, detectable UV teeb ib qho stain uas tseem nyob ntawm daim tawv nqaij thiab khaub ncaws rau ob peb lub lis piam. Kev tswj hwm zoo ib yam li SelectaDNA labeling spray.
