Qhov teeb meem ntawm ib puag ncig muaj kuab paug tau dhau los ua qhov teeb meem kub hauv ntiaj teb niaj hnub no.Ib puag ncig muaj kuab paug, feem ntau tshwm sim los ntawm cov tshuaj lom neeg, suav nrog huab cua, dej, thiab av ua paug.Cov pa phem no tsis yog tsuas yog ua rau kev puas tsuaj ntawm biodiversity, tab sis kuj ua rau tib neeg kev noj qab haus huv.Cov pa phem ntau ntxiv uas niaj hnub xav tau kev txhim kho zoo dua lossis kev tshawb pom thev naus laus zis tam sim ntawd.Nanotechnology muaj ntau yam zoo los txhim kho ib puag ncig cov thev naus laus zis uas twb muaj lawm thiab tsim cov thev naus laus zis tshiab uas zoo dua li cov thev naus laus zis tam sim no.Hauv qhov kev nkag siab no, nanotechnology muaj peb lub peev xwm tseem ceeb uas tuaj yeem siv rau hauv thaj chaw ib puag ncig, suav nrog kev ntxuav (kev kho) thiab kev ua kom huv huv, kev kuaj xyuas cov kab mob (sensing thiab nrhiav pom), thiab kev tiv thaiv kev ua qias tuaj.

Nyob rau hauv lub ntiaj teb niaj hnub no uas cov kev lag luam tau niaj hnub thiab niaj hnub, peb ib puag ncig muaj ntau hom pa phem tawm los ntawm tib neeg kev ua ub no lossis cov txheej txheem kev lag luam.Piv txwv ntawm cov pa phem no yog carbon monoxide (CO), chlorofluorocarbons (CFCs), hlau hnyav (arsenic, chromium, lead, cadmium, mercury thiab zinc), hydrocarbons, nitrogen oxides, organic compounds (volatile organic compounds thiab dioxins), sulfur dioxide thiab feem ntau.Tib neeg cov dej num, xws li roj, thee thiab roj combustion, muaj peev xwm tseem ceeb los hloov emissions los ntawm tej yam ntuj tso.Ntxiv nrog rau kev ua pa phem, tseem muaj dej paug los ntawm ntau yam, suav nrog kev pov tseg pov tseg, cov roj nchuav, xau ntawm cov chiv, tshuaj tua kab thiab tshuaj tua kab, los ntawm cov txheej txheem kev lag luam thiab combustion thiab extraction fossil fuels.

Cov kab mob feem ntau pom muaj sib xyaw hauv huab cua, dej thiab av.Yog li, peb xav tau ib lub tshuab uas muaj peev xwm saib xyuas, kuaj xyuas thiab, yog tias ua tau, ntxuav cov pa paug ntawm huab cua, dej thiab av.Hauv cov ntsiab lus no, nanotechnology muaj ntau yam peev xwm thiab thev naus laus zis los txhim kho qhov zoo ntawm ib puag ncig uas twb muaj lawm.

Nanotechnology muaj peev xwm tswj tau qhov teeb meem ntawm nanoscale thiab tsim cov ntaub ntawv uas muaj cov khoom tshwj xeeb nrog cov haujlwm tshwj xeeb.Kev soj ntsuam los ntawm cov European Union (EU) cov xov xwm uas tau xaiv tau pom tias muaj kev cia siab zoo nrog rau qhov muaj feem cuam tshuam / kev pheej hmoo cuam tshuam nrog nanotechnology, uas feem ntau ntawm lawv tau raug ntaus nqi rau kev cia siab ntawm kev txhim kho hauv lub neej thiab kev noj qab haus huv.
