Key Takeaways
- Kev tawg tsis ntev los no tuaj yeem tso cai siv DNA los khaws cov ntaub ntawv ntau rau lub sijhawm ntev.
- Ib tus kws tshaj lij tau hais tias DNA khaws cov thev naus laus zis tuaj yeem tuav ntau dua 50, 000 npaug ntawm cov ntaub ntawv ntau npaum li daim npav microSD nco hauv tib qhov chaw.
- Tab sis DNA khaws cia ntsib teeb meem engineering ua ntej nws ua lag luam ua tau.
Tej zaum koj yuav tuaj yeem khaws koj cov ntaub ntawv siv DNA sai sai.
Kev teb ntawm DNA cov ntaub ntawv khaws cia yog nrawm nrawm nrog cov ntawv tshaj tawm tsis ntev los no ntawm kev tawg los ntawm cov kws tshawb fawb hauv Tebchaws Meskas thiab Tuam Tshoj. Cov kws tshaj lij hais tias DNA muaj lub peev xwm los ntim cov ntaub ntawv ntau ntxiv rau hauv qhov chaw me dua li cov tsav tsheb.
"Koj tuaj yeem xav txog koj daim npav nco microSD ib terabyte; nws hnyav txog 250 milligrams," Hieu Bui, tus xibfwb uas kawm DNA suav ntawm Lub Tsev Kawm Qib Siab Catholic University, hais rau Lifewire hauv kev xam phaj email. "Cov khoom siv DNA hnyav tib yam tuaj yeem tuav tau 53,000 npaug ntawm cov ntaub ntawv ntau dua li ntawm daim npav microSD, thiab tej zaum koj yuav tsis tas yuav lwm daim npav nco ntev."
A Natural Hard Drive
Lub tswv yim ntawm kev khaws cov ntaub ntawv hauv DNA, cov molecule tsim los ntawm ob lub polynucleotide chains uas coil nyob ib ncig ntawm ib leeg los tsim ob lub helix nqa cov lus qhia caj ces, tau nyob ib ncig ntawm kaum xyoo tab sis tau cuam tshuam los ntawm cov teeb meem kev lag luam.
Nyob rau hauv daim ntawv tshawb fawb, Microsoft tshaj tawm thawj nanoscale DNA cia tus kws sau ntawv. Cov kws tshawb fawb tau hais tias lawv tuaj yeem ncav cuag DNA sau qhov ceev ntawm 25 x 10^6 ib ntus ib square centimeter, uas mus txog qhov tsawg kawg nkaus sau nrawm uas yuav tsum tau ua rau DNA khaws cia.
"Ib kauj ruam tom ntej yog txhawm rau txhawm rau digital logic hauv lub nti kom tso cai rau tus kheej tswj hwm ntau lab tus electrode me ntsis los sau kilobytes ib ob ntawm cov ntaub ntawv hauv DNA," Microsoft cov kws tshawb fawb tau sau rau hauv blog ncej. "Los ntawm qhov ntawd, peb pom cov thev naus laus zis mus txog arrays uas muaj ntau lab tus electrodes muaj peev xwm khaws cia megabytes ib ob ntawm cov ntaub ntawv hauv DNA."
Cov kws tshawb fawb Suav tseem tsis ntev los no tshaj tawm txog DNA khaws cia. Tsis zoo li lwm txoj hauv kev uas khaws cov ntaub ntawv ntawm cov kab ntev ntev, tus kws tshawb fawb tau faib cov ntsiab lus ua ntu thiab khaws cov no ntawm cov electrodes sib txawv.
Thiab cov kws tshawb fawb ntawm Georgia Tech Research Institute tau hais tias tsis ntev los no lawv tau ua kev nce qib mus rau lub hom phiaj ntawm microchip tshiab tuaj yeem loj hlob DNA strands uas tuaj yeem muab cov ntaub ntawv ceev ceev 3D cov ntaub ntawv khaws cia ntawm tus nqi qis thiab muaj peev xwm. tuav cov ntaub ntawv ntawd ntau pua xyoo.
"Peb tau tuaj yeem qhia tau tias nws tuaj yeem loj hlob DNA mus rau qhov ntev uas peb xav tau, thiab ntawm qhov loj me uas peb mob siab txog kev siv cov chips no," Nicholas Guise, ib tus kws tshawb fawb., hais hauv xov xwm tshaj tawm."Lub hom phiaj yog kom loj hlob ntau lab tus cim, kev ywj pheej nyob thoob plaws lub nti los ntawm cov microwells, nrog rau txhua qhov ua haujlwm ua ib qho me me electrochemical bioreactor.
Ntau Cov Ntaub Ntawv, Tsawg Qhov Chaw
DNA tuaj yeem hloov pauv cov ntaub ntawv khaws cia, tab sis nws tsis paub meej thaum twg koj yuav siv thev naus laus zis hauv koj cov khoom siv.
"Nyob rau yav tom ntej, cov neeg siv tuaj yeem cia siab tias DNA khaws cov ntaub ntawv los tuav ntau cov ntaub ntawv, nyob deb dua qhov chaw, siv lub zog ntsuab me me, thiab khaws cov ntaub ntawv digital dhau ntawm tus tswv lub neej," Bui hais.
Tab sis nws tsis zoo li tus neeg siv nruab nrab yuav tau txais txiaj ntsig los ntawm DNA cov ntaub ntawv khaws cia txhua lub sijhawm sai sai, tus kws tshaj lij cov ntaub ntawv Nick Heudecker hais rau Lifewire hauv kev xam phaj email. Nws hais tias thev naus laus zis tuaj yeem yog qhov zoo tagnrho rau khaws cov ntaub ntawv loj heev nyob rau lub sijhawm ntev. Cov ntaub ntawv khaws cia zoo li no yuav pab tau rau cov koom haum xws li Library of Congress lossis cov zej zog txawj ntse ntau dua li ntawm lub laptop.
"Tam sim no, cov tib neeg siv DNA rau cov ntaub ntawv khaws cia yog feem ntau gimmicks, zoo li khaws koj lub hnab nyiaj bitcoin passcode li DNA kom koj tsis tuaj yeem poob nws," Heudecker hais. "Lub sijhawm dhau los, koj tuaj yeem pom cov lag luam siv huab-raws li DNA cov ntaub ntawv khaws cia rau off-load lawv qhov tseem ceeb tshaj plaws, tab sis tsawg kawg tau nkag mus, cov ntaub ntawv rau DNA, tab sis qhov ntawd yog 5-10 xyoo tawm ntawm qhov tsawg kawg nkaus."
DNA cia tseem ntsib teeb meem engineering ua ntej nws tuaj yeem ua lag luam. Tus nqi siab, thiab kev nrawm nrawm, Heudecker tau hais. Cov txheej txheem ntawm kev siv DNA rau kev khaws cia kuj nyuaj heev.
"Tsis zoo li niaj hnub no cov ntaub ntawv khaws cia, DNA 'disk drives' khiav ntawm cov tshuaj thiab cov kua dej," Heudecker hais. "Lawv zoo li kev sim sim, nrog cov raj thiab cov twj, dua li lub computer."
