Lub neej ntawm nanomaterials (cov ntaub ntawv muaj nanoparticles) nws tus kheej tsis yog qhov phom sij. Tsuas yog qee qhov ntawm nws yog qhov phom sij, tshwj xeeb tshaj yog lawv lub chaw muaj zog thiab txhim kho lub zog. Tsuas yog thaum muaj qee yam ntawm nanoparticles yam tsis zoo rau biology lossis ib puag ncig, peb ntsib kev phom sij tiag tiag.
Txhawm rau sib tham txog qhov cuam tshuam ntawm nanomaterials nyob rau kev noj qab haus huv thiab ib puag ncig, peb yuav tsum paub qhov txawv ob hom ntawm nanostructures:
Nano-qhov loj me me tau sib sau ua ke rau ntawm ib txheej, khoom siv lossis khoom siv ntawm nanocomposite, nanosurface qauv lossis nanocomponent (cov khoom siv hluav taws xob, cov khoom siv kho qhov muag, thiab lwm yam), tseem hu ua nanoparticles ruaj khov.
GG quot; Free" nanoparticles, tsis hais seb lawv puas tau khaws cia hauv qee cov kauj ruam ntawm kev tsim khoom lossis siv ua ib tus neeg nanoparticles.
Cov nanoparticles dawb tej zaum yuav nano-qhov loj tib cov khoom, cov sib txuas, lossis cov khoom siv sib xyaw ua ke, xws li" coated" nanoparticles lossis" tub ntxhais-plhaub" nanoparticles nyob rau hauv uas ib lub ntsiab yog coated nrog lwm yam khoom.
Hauv cov caij nyoog niaj hnub no, qhov kev lees paub yog tias txawm tias peb yuav tsum mob siab rau cov ntaub ntawv nrog cov nanoparticles ruaj khov, nanoparticles dawb yog qhov kev txhawj xeeb tshaj plaws.
Vim hais tias nanoparticles yog qhov txawv ntawm lawv cov neeg ua haujlwm niaj hnub hais tias lawv cov kev phom sij tsis tuaj yeem yog los ntawm kev paub tshuaj lom. Qhov kev sib tham txog kev noj qab haus huv thiab ib puag ncig ntawm dawb nanoparticles yog qhov tseem ceeb.
Dab tsi nyuab dua yog tias thaum peb tham txog nanoparticles, peb yuav tsum paub tias hmoov los yog kua muaj nanoparticles yuav luag tsis muaj monodispersed, tab sis muaj ntau qhov ntau thiab tsawg hauv qee yam. Qhov no ua rau kev soj ntsuam tshawb xyuas nyuaj dua, vim cov nanoparticles loj loj yuav muaj cov yam ntxwv txawv ntawm cov me me. Ntxiv mus, nanoparticles muaj ib tug nyiam mus polymerize, thiab polymerized nanoparticles muaj tus cwj pwm sib txawv los ntawm ib tus neeg nanoparticles.
