Dukoresha kuki kugirango tunoze uburambe.Mugukomeza gushakisha kururu rubuga, wemera gukoresha kuki.Amakuru yinyongera.
Nanotubes ya Halloysite (HNT) mubisanzwe iboneka ryibumba ryibumba rishobora gukoreshwa mubikoresho byateye imbere bitewe nuburyo bwihariye bwimyanya myumbati, ibinyabuzima, hamwe nubukanishi nubuso.Ariko, guhuza ibyo bikoresho bya nanotube biragoye kubera kubura uburyo butaziguye.

Ni muri urwo rwego, ingingo yasohotse mu kinyamakuru ACS Applied Nanomaterials itanga ingamba zifatika zo guhimba inzego za HNT zateganijwe.Mu kumisha amazi yabo akoresheje rotor ya magnetique, nanotubes yibumba yahujwe kumurongo wikirahure.
Amazi amaze guhinduka, gukurura amazi ya GNT bitera imbaraga zo gukata kuri nanotube yibumba, bigatuma bahuza muburyo bwimpeta zikura.Hakozwe iperereza ku bintu bitandukanye bigira ingaruka ku gishushanyo cya HNT, harimo kwibanda kuri HNT, kwishyuza nanotube, ubushyuhe bwumye, ingano ya rotor, nubunini bwigitonyanga.
Usibye ibintu bifatika, gusikana microscopi ya electron (SEM) hamwe na microscopi yumucyo (POM) byakoreshejwe mukwiga microscopique morphologie na birefringence yimpeta zinkwi za HNT.
Ibisubizo byerekana ko iyo intumbero ya HNT irenze 5 wt%, nanotube y ibumba igera ku guhuza neza, kandi ubunini bwa HNT bwongera ubuso bwubuso nubunini bwuburyo bwa HNT.
Byongeye kandi, uburyo bwa HNT bwateje imbere kwaguka no gukwirakwiza ingirabuzimafatizo za fibroblast (L929), byagaragaye ko zikura zikomatanya ibumba nanotube ikurikije uburyo bwo guhuza amakuru.Kubwibyo, uburyo bworoshye kandi bwihuse bwo guhuza HNT kumasoko akomeye afite ubushobozi bwo guteza imbere matrise-selile.
Nanoparticles imwe-imwe (1D) nka nanowire, nanotubes, nanofibers, nanorods na nanoribbone kubera imiterere yihariye ya mashini, elegitoroniki, optique, ubushyuhe, ibinyabuzima na magneti.
Nanoys ya Halloysite (HNTs) ni nanotube isanzwe yibumba ifite diameter yo hanze ya nanometero 50-70 hamwe nu mwobo w'imbere wa nanometero 10-15 hamwe na formula Al2Si2O5 (OH) 4 · nH2O.Kimwe mu bintu bidasanzwe biranga nanotubes ni imiterere itandukanye yimbere / yo hanze (aluminium oxyde, Al2O3 / dioxyde de silicon, SiO2), ibemerera guhinduka.
Bitewe na biocompatibilité hamwe nuburozi buke cyane, iyi nanotube y ibumba irashobora gukoreshwa mubinyabuzima, imiti yo kwisiga no kwita ku nyamaswa kuko nanotube yibumba ifite nanosafeti nziza mumico itandukanye.Nanotubes y ibumba ifite ibyiza byo kugiciro gito, kuboneka kwinshi, no guhindura imiti ya silane yoroshye.
Icyerekezo cyo guhuza bivuga ibintu byerekana ingaruka za selile zishingiye kumiterere ya geometrike nka nano / micro grooves kuri substrate.Hamwe niterambere ryubwubatsi bwa tissue, ibintu byo kugenzura imikoreshereze byakoreshejwe cyane kugirango bigire ingaruka kumikorere no mumikorere ya selile.Nyamara, uburyo bwibinyabuzima bwo kugenzura imiterere ntibusobanutse neza.
Ibikorwa byubu birerekana inzira yoroshye yo gushiraho imiterere yimikurire ya HNT.Muri ubu buryo, nyuma yo gukoresha igitonyanga cya HNT kumurongo wikirahure kizengurutse, igitonyanga cya HNT kigabanywa hagati yimiterere ibiri ihuza (slide na magnetiki rotor) kugirango ihinduke ikanyura muri capillary.Igikorwa kirabitswe kandi cyoroshe.guhumeka kwinshi kwishongora kumpera ya capillary.
Hano, imbaraga zo gukata zakozwe na rotorike ya magnetiki rotor itera HNT kumpera ya capillary gushira hejuru kunyerera muburyo bwiza.Amazi amaze guhinduka, imbaraga zo guhuza zirenze imbaraga zogusunika, zisunika umurongo uhuza werekeza hagati.Kubwibyo, muburyo bwo guhuza imbaraga zogosha nimbaraga za capillary, nyuma yo guhumeka kwuzuye kwamazi, hashyizweho igiti-impeta ya HNT.
Mubyongeyeho, ibisubizo bya POM byerekana birefringence igaragara ya anisotropic HNT imiterere, amashusho ya SEM yitirirwa guhuza guhuza ibumba nanotubes.
Hiyongereyeho, selile L929 yatejwe imbere yumwaka-ibumba ryibumba nanotubes hamwe nubushakashatsi butandukanye bwa HNT byasuzumwe hashingiwe ku buryo bwo guhuza amakuru.Mugihe, selile L929 yerekanaga ikwirakwizwa ryibumba kuri nanotube yibumba muburyo bwimpeta zo gukura hamwe 0.5 wt.% HNT.Muburyo bwa nanotube yibumba hamwe na NTG yibanda kuri 5 na 10 wt%, selile ndende ziboneka mubyerekezo bya nanotube yibumba.
Mugusoza, macroscale HNT ikura impeta yimpimbano yahimbwe hakoreshejwe uburyo buhendutse kandi bushya bwo gutunganya nanoparticles muburyo bukurikirana.Imiterere yimiterere yibumba nanotubes yibasiwe cyane nubushakashatsi bwa HNT, ubushyuhe, ubushyuhe bwo hejuru, ingano ya rotor, nubunini bwigitonyanga.Ubushuhe bwa HNT kuva kuri 5 kugeza kuri 10 wt.
Guhuza ibumba nanotubes ku cyerekezo cyingufu zogosha byemejwe hakoreshejwe amashusho ya SEM.Hamwe no kwiyongera kwa NTT, umubyimba nubukonje bwa NTG byiyongera.Kubwibyo, umurimo wubu uratanga uburyo bworoshye bwo kubaka ibyubaka kuva nanoparticles hejuru yinini.
