Mechanical engineering ntawm qib molecular tej zaum yuav yog lub tuam txhab txoj kev npau suav los txog. Txawm li cas los xij, nyob rau lub sijhawm ntev, cov nanoparticles hauv koj lub cev tau kawm me ntsis, tshwj xeeb tshaj yog thaum nws los txog rau kev noj qab haus huv. Ntxiv rau qhov kev lag luam tshiab tau txais txiaj ntsig zoo heev, muaj lub cev loj zuj zus ntawm cov ntaub ntawv toxicological qhia tias cov khoom siv nanotechnology, thaum noj, tuaj yeem ua rau lub hlwb puas (raws li pom los ntawm cov ntses bass thaj tsam loj) thiab yog li ntawd yuav tsum tau kuaj tag nrho rau lawv txoj kev nyab xeeb.

Cov nanoparticles muaj peev xwm nkag mus rau ntawm daim tawv nqaij, qhia tias muaj peev xwm cuam tshuam tsis zoo rau lub cev tiv thaiv kab mob, lossis nkag mus rau hauv cov hlab ntsha. Piv txwv li, qee cov tshuaj pleev thaiv hnub rau ntawm cov txee niaj hnub no muaj cov nanoparticles uas muaj peev xwm nkag mus rau ntawm daim tawv nqaij, txav mus los ntawm cov kabmob uas tsis paub txog kev noj qab haus huv. FDA tau tshaj tawm ob peb txoj cai hais txog kev siv nanoparticles hauv tshuaj pleev ib ce.

Thomas Fons ntawm Australian National University, uas yog Australian Pawg Saib Xyuas Kev Tshawb Fawb Txog Kev Noj Qab Haus Huv Hauv Pej Xeem Nanotechnology, tau hais tias qhov kev tshawb pom los ntawm kev tshawb fawb yog qhov tseem ceeb, nyiam qhov yuav tsum tau sau npe, thiab cov tuam txhab lag luam yuav tsum tau thov kom muaj cov ntaub ntawv muaj kev nyab xeeb rau lawv cov khoom. "Cov txiaj ntsig tshawb fawb pom tau tias cov nanoparticles muaj peev xwm ua rau cov hlwb muaj sia nyob, thiab qhov no yuav tsum tau siv txoj cai ceev faj," nws hais.

Raws li lub ntiaj teb no tus thawj coj kev lag luam nanotechnology analyst, Helmut Kaiser Consultancy, nyob rau hauv 2005 muaj txog 300 nanotechnology-raws li cov khoom noj khoom haus nyob rau hauv lub ntiaj teb no kev ua lag luam, nrog rau kwv yees li kev lag luam loj ntawm US $ 5.4 billion. Yog li ntawd nws yog thaum ntawd.

Thiab los ntawm 2015, nws kwv yees, nanotechnology yuav siv nyob rau hauv 40 feem pua ntawm cov zaub mov kev lag luam. Raws li cov kws pab tswv yim no, nanotechnology-ua zaub mov nrog cov khoom noj muaj txiaj ntsig zoo thiab tib lub tsw thiab kev ntxhib los mos raws li cov khoom tsim tawm yuav dhau los ua tus qauv los ntawm 2040.

Nws yog qhov tseeb tias nanotechnology twb muaj nyob rau hauv qee cov khoom noj thiab kev zoo nkauj (nrog rau kev tiv thaiv kev laus thiab tshuaj pleev thaiv hnub). Tag nrho ib ncig ntawm "ntse" ntim thiab taug qab. Pom tsis pom (rau qhov muag liab qab thiab qhov chaw ntawm lub tshuab ntsuas), noj tau nanowrap nrog barcode ntxiv tuaj yeem tsis tsuas yog nthuav tawm cov khoom lwj thaum ntxov, tab sis kuj txhim kho saj ntawm zaub mov lossis txhua yam uas hu ua nws. Cov neeg tsim khoom rub lawv txhais tes hauv kev zoo siab vim tias muaj zaub mov yuav tsis nyob ntawm cov peev txheej tsawg, huab cua phem, teeb meem dej, thiab lwm yam. Txoj kev niaj hnub pub rau tag nrho lub ntiaj teb no.

Thiab tsis txhob tos rau cov ntaub ntawv nanoparticle cov ntawv sau rau hauv koj cov khoom. Txawm hais tias cov neeg muag khoom yuav zoo siab los pleev xim rau qhov zoo siab ntawm qhov ploj ntawm wrinkles lossis flawless xim ntawm koj lub ntsej muag, kuj muaj kev noj qab haus huv thiab ib qho downside rau npib.

Kev sib cav txog pej xeem nyob qhov twg ntawm kev sau npe ntawm nanoparticles hauv koj cov khoom, tshuaj pleev ib ce, lossis cov kev pheej hmoo cuam tshuam? Tej zaum nyob rau hauv Karaganda … Zoo li cov thawj coj nom tswv tseem tab tom sib cav txog qhov yuav tsum tau sau npe ntawm GMOs.

Thaum cov nas tsuag tsis muaj zaub mov noj thiab muab cov kev xaiv noj zaub mov los yog hloov noob caj noob ces, lawv khiav ncaj nraim mus rau ntuj. Thiab tsuas yog thaum lawv tsis muaj kev xaiv tab sis tuag tshaib plab, lawv noj GMO qos yaj ywm.

Yog li lwm zaus koj tuaj hla ib yam dab tsi nrog lo lus "ntse" … xav txog seb nws yuav txhais li cas. Tshawb nrhiav seb koj tuaj yeem ua li cas txog cov peev txheej ntawm qhov yuav tsum tau siv rau sab hauv lossis sab nraud rau koj lub cev. Ntse mini micro computers los tswj koj cov tawv nqaij thiab lub cev kua?

Cov xeeb leej xeeb ntxwv yuav tau raug kev txom nyem los ntawm nanoparticles

Nanoparticles, tshwj xeeb tshaj yog titanium dioxide, tam sim no tuaj yeem pom nyob txhua qhov chaw: los ntawm cov tshuaj pleev ib ce thiab tshuaj pleev thaiv hnub rau dyes thiab vitamins.

Cov kws tshaj lij txhua lub sijhawm tam sim no thiab tom qab ntawd pom lawv cov txuj ci tseem ceeb - lawv xav tias muaj peev xwm tiv thaiv cov ntaub so ntswg los ntawm kev sib kis, tua tus kab mob khaub thuas, thiab lwm yam. Tsis tas li ntawd, titanium dioxide yeej ib txwm suav tias yog cov khoom tsis muaj tshuaj lom. Thiab tsis ntev los no, cov kws tshawb fawb los ntawm University of Koblenz-Landau (Lub Tebchaws Yelemees) tau tsim tias titanium dioxide nanoparticles yog qhov tseeb, lub sijhawm foob pob. Lawv tuaj txog qhov xaus no, raws li tau tshaj tawm hauv phau ntawv xov xwm PloS ONE, tom qab ua qhov kev sim ntawm daphnia - me crustaceans uas nyob hauv cov dej hauv av (lawv kuj hu ua dej fleas). Qhov tseeb yog tias daphnia feem ntau yog siv los ntsuas cov khoom ntawm ntau yam tshuaj pleev ib ce thiab tshuaj rau kev tsis haum xeeb.

Cov kws tshawb fawb German tau tso Daphnia hauv dej uas muaj titanium dioxide nanoparticles. Lawv qhov concentration yog 50 npaug tsawg dua qhov uas suav tias yog qhov txaus ntshai rau lub neej ntawm cov tsiaj no. Qhov chaw no tsis cuam tshuam rau txhua yam ntawm lub neej ua haujlwm ntawm Daphnia. Tom qab ntawd cov kws tshawb fawb tau ua tib yam kev sim nrog cov xeeb ntxwv uas tsim los ntawm cov crustaceans. Nws tau dhau los ua ob mus rau tsib npaug ntau dua rau ib puag ncig - txawm tias qhov tsis tseem ceeb ntawm titanium dioxide nanoparticles cuam tshuam tsis zoo rau lawv lub peev xwm ua luam dej.

"Kev tshawb fawb lees paub tias cov txiaj ntsig ntawm nanomaterials, vim lawv qhov tshwj xeeb zoo, tuaj yeem xav tsis thoob. Tab sis cov kev tshawb fawb classic tsis muab lub sijhawm los ntsuas qhov kev pheej hmoo ntawm kev siv cov ntaub ntawv no siab npaum li cas, vim tias lawv tsis ntsuas lawv cov txiaj ntsig ntawm lub cev mus ntev, "sau lub taub hau ntawm pawg tshawb fawb, Ralph Schultz. Raws li cov kws tshawb fawb, kev saib xyuas yuav tsum tau them rau qhov no, txij li txhua xyoo ib qho kev loj hlob ntawm nanomaterials nkag mus rau ib puag ncig nrog rau kev lag luam thiab cov khoom pov tseg hauv tsev. Tsis muaj leej twg paub lawv coj li cas rau ntawd.
