Nyob rau hauv xyoo tas los no, nano-drug technology yog ib tug nrov tshiab technology nyob rau hauv kev npaj tshuaj technology. Cov tshuaj nano xws li nanoparticles, pob lossis nano capsule nanoparticles raws li lub cev muaj zog, thiab kev ua tau zoo ntawm cov khoom hauv ib txoj hauv kev ua ke tom qab cov tshuaj, kuj tuaj yeem ua ncaj qha rau kev ua haujlwm ntawm nanoparticles.
Piv nrog rau cov tshuaj pa, nano-drugs muaj ntau yam zoo uas yog incomparable rau cov pa pa:
Cov tshuaj tso tawm qeeb, hloov ib nrab-lub neej ntawm cov tshuaj hauv lub cev, ua kom lub sijhawm ntev ntawm cov tshuaj;
Ib lub hom phiaj tshwj xeeb tuaj yeem ncav cuag tom qab tau ua rau hauv cov tshuaj coj;
Txhawm rau txo cov koob tshuaj, txo lossis tshem tawm cov tshuaj lom neeg lom nyob rau hauv qhov chaw ntawm kev ua kom muaj txiaj ntsig zoo;
Lub membrane thauj mechanism yog hloov mus ua kom cov permeability ntawm cov tshuaj mus rau lub biofilm, uas yog pab tau rau cov tshuaj transdermal absorption thiab ua si ntawm cov tshuaj ua tau zoo.
Yog li ntawd rau cov kev xav tau nrog kev pab los ntawm ib tus neeg nqa khoom kom xa cov tshuaj mus rau cov hom phiaj tshwj xeeb, muab kev ua si rau lub luag haujlwm ntawm kev kho mob ntawm nanodrugs, kev tsim cov cab kuj los txhim kho cov txiaj ntsig ntawm kev siv tshuaj yeeb tshuaj yog qhov tseem ceeb.
Tsis ntev los no cov xov xwm tshaj tawm tau hais tias lub tsev kawm ntawv qib siab tshiab sab qab teb wales, Australia, cov kws tshawb fawb tau tsim txoj hauv kev tshiab, tuaj yeem hloov cov duab ntawm nano tshuaj cab cab, qhov no yuav pab thauj cov tshuaj tiv thaiv kab mob tso tawm mus rau hauv cov qog, txhim kho cov nyhuv ntawm cov tshuaj tiv thaiv. - tshuaj mob qog noj ntshav.
Polymer molecules nyob rau hauv kev daws yuav cia li tsim vesicle hollow spherical qauv ntawm lub polymer, nws muaj qhov zoo ntawm kev ruaj ntseg, kev ua haujlwm muaj ntau haiv neeg yog dav siv los ntawm cov neeg nqa tshuaj, tab sis, los ntawm qhov sib txawv, xws li cov kab mob thiab cov kab mob hauv qhov xwm txheej yog cov hlab ntsha, rods. , thiab cov qauv uas tsis yog kheej kheej kheej kheej tuaj yeem nkag mus rau hauv lub cev yooj yim dua. Vim hais tias cov vesicles polymer yog ib qho nyuaj rau tsim ib tug nonspherical qauv, qhov no txwv lub peev xwm ntawm lub polymer xa tshuaj mus rau nws cov hom phiaj nyob rau hauv tib neeg lub cev mus rau ib tug tej yam kev mob.
Cov kws tshawb fawb Australian tau siv cryoelectron microscopy los soj ntsuam cov qauv kev hloov pauv ntawm polymer molecules hauv kev daws. Lawv pom tias los ntawm kev hloov cov dej hauv cov kuab tshuaj, cov duab thiab qhov loj ntawm cov vesicles polymer tuaj yeem hloov kho los ntawm kev hloov cov dej hauv cov kuab tshuaj.
Kev tshawb fawb tus kws sau ntawv thiab tsev kawm ntawv qib siab tshiab sab qab teb wales lub koom haum ntawm chemistry ntawm Pine parr sol, hais tias: "Qhov kev tawg no txhais tau tias peb tuaj yeem tsim cov vesicle polymer tuaj yeem hloov nrog ib puag ncig, xws li lub oval lossis tubular, thiab cov tshuaj pob hauv nws." Cov pov thawj ua ntej qhia tau hais tias ntau lub ntuj tsim, cov neeg nqa khoom tsis yog cov nano-cov tshuaj muaj feem ntau nkag mus rau cov qog hlwb.
Cov kev tshawb fawb tau luam tawm hauv online hauv qhov tseeb qhov teeb meem ntawm phau ntawv xov xwm xwm kev sib txuas lus.
