EPA cov kws tshawb fawb tab tom kawm cov cim tshuaj thiab lub cev ntas ntawm nanomaterials (xws li qhov loj me, zoo li, tshuaj muaj pes tsawg leeg, ruaj khov, thiab lwm yam) los pab tsim cov qauv kev kwv yees los txiav txim seb qhov twg nanomaterials tej zaum yuav ua rau muaj kev pheej hmoo siab dua thiab cov uas xav tias yuav muaj kev cuam tshuam me ntsis.

Tsis tas li ntawd, nanomaterials siv li cas hauv tshuaj thiab kev tshawb fawb?

Ib daim ntawv thov ntawm nanotechnology hauv tshuaj kho mob tam sim no tau tsim muaj kev siv nanoparticles xa tshuaj, tshav kub, lub teeb lossis lwm yam khoom siv rau cov hlwb tshwj xeeb (xws li cov qog nqaij hlav cancer). Cov txheej txheem no txo qis kev puas tsuaj rau cov hlwb noj qab haus huv hauv lub cev thiab tso cai rau kev kuaj pom tus kab mob ua ntej.

Qhov thib ob, nanomaterials saib li cas? Feem ntau cov ntaub ntawv nanoscale tsawg dhau los ua pom nrog lub qhov muag liab qab thiab txawm tias nrog cov pa kuaj mob microscopes. Cov ntaub ntawv uas tsim los rau qhov me me no feem ntau hu ua engineered nanomaterials (ENMs), uas tuaj yeem coj cov khoom siv kho qhov muag, sib nqus, hluav taws xob, thiab lwm yam khoom.

Hauv qhov no, dab tsi yog nanomaterials siv rau?

Daim ntawv thov. Cov ntaub ntawv nano yog siv nyob rau hauv ntau yam, tsim cov txheej txheem, cov khoom thiab kev kho mob nrog rau cov xim, lim, rwb thaiv tsev thiab lubricant additives. Hauv kev kho mob Nanozymes yog nanomaterials nrog cov yam ntxwv zoo li enzyme.

Cov piv txwv ntawm nanomaterials yog dab tsi?

Piv txwv ntawm nanomaterials yog carbon nanotube, nanoparticle, hlau roj hmab, quantum dots, nanopores thiab ntau yam ntxiv. Nanotechnology, luv luv rau "nanotech", yog txoj kev tshawb fawb txog kev tswj cov teeb meem ntawm atomic thiab molecular nplai.
