Nqe lus piav qhia:
Ag nanopowder tuaj yeem siv rauantibacterial:
Cov tshuaj tua kab mob ntawm cov nyiaj tuaj yeem taug qab rov qab rau cov neeg Greek thiab Loos, uas ua rau nws lub sijhawm haus dej los ntawm kev khaws dej hauv cov khoom siv nyiaj.Silver ions raug tso tawm los ntawm lub thawv ntim phab ntsa, thiab cov nyiaj ions cuam tshuam nrog cov kab mob tseem ceeb ntawm cov enzymes thiab cov protein sulfhydryl pawg kom ua tiav cov tshuaj tua kab mob.Qhov no cuam tshuam rau cell respiration thiab ion thauj mus rau hauv daim nyias nyias, thiab tus kab mob ua rau cell tuag.Lwm txoj hauv kev los tiv thaiv kab mob rau cov tshuaj lom ntawm cov nyiaj nanoparticles kuj tau thov.Silver nanoparticles tuaj yeem thauj tog rau nkoj thiab tom qab ntawd nkag mus rau cov kab mob ntawm cov phab ntsa ntawm tes, ua rau muaj kev puas tsuaj rau lub cell membrane.Kev tsim cov pa oxygen reactive nyob rau saum npoo ntawm cov nyiaj nanoparticles tuaj yeem ua rau oxidative kev nyuaj siab thiab muab cov txheej txheem ntxiv rau kev puas tsuaj ntawm tes.Qhov tshwj xeeb toxicity rau cov kab mob thaum tswj tsis tshua muaj toxicity rau tib neeg tau ua rau cov nyiaj nanoparticles tau muab tso rau hauv ntau yam khoom, nrog rau cov ntaub qhwv lub qhov txhab, cov ntaub ntawv ntim khoom thiab cov txheej txheem tiv thaiv fouling.
Bioimaging tags thiab lub hom phiaj
Silver nanoparticles muaj qhov ua tau zoo tshaj plaws hauv kev nqus thiab tawg lub teeb, thiab tuaj yeem siv rau kev sau ntawv thiab duab.Lub siab tawg ntu ntu ntawm cov nanoparticles tuaj yeem tso cai rau tus kheej cov nyiaj nanoparticles tuaj yeem ua duab nyob rau hauv qhov chaw tsaus nti microscope lossis hyperspectral imaging system.Los ntawm kev sib txuas biomolecules (xws li cov tshuaj tiv thaiv kab mob lossis peptides) rau lawv qhov chaw, cov nyiaj nanoparticles tuaj yeem raug tsom rau cov hlwb lossis cov khoom siv ntawm tes.Qhov txuas ntawm lub hom phiaj molecule rau saum npoo tuaj yeem ua tiav los ntawm adsorption rau saum npoo ntawm nanoparticle, lossis los ntawm covalent coupling lossis lub cev adsorption.
Cia txias:
Silver nanopowders yuav tsum tau muab cia rau hauv qhov chaw qhuav, txias, yuav tsum tsis txhob raug huab cua kom tsis txhob muaj kev tiv thaiv oxidation thiab agglomeration.
