N'akụkụ a, otu akụkọ e bipụtara n'akwụkwọ akụkọ ACS Applied Nanomaterials na-atụpụta atụmatụ dị mma maka imepụta ihe owuwu HNT.Site na ihicha ha aqueous dispersions iji a magnetik rotor, ụrọ nanotubes e kwekọọ na a iko mkpụrụ.
Ka mmiri na-ekupụ, mkpali nke GNT aqueous mgbasa na-emepụta ike shiee na ụrọ nanotubes, na-eme ka ha kwekọọ n'ụdị mgbanaka uto.A nyochara ihe dị iche iche na-emetụta ụkpụrụ HNT, gụnyere itinye uche HNT, ụgwọ nanotube, ihicha okpomọkụ, nha rotor, na ụda droplet.
Na mgbakwunye na ihe anụ ahụ, a na-eji nyocha eletrọnịkị eletrọnịkị (SEM) na polarizing ìhè microscopy (POM) mee ihe iji mụọ morphology microscopic na birefringence nke mgbanaka osisi HNT.
Nsonaazụ na-egosi na mgbe ntinye nke HNT gafere 5 wt%, ụrọ nanotubes na-enweta nhazi zuru oke, na ntinye uche HNT dị elu na-eme ka ọ dịkwuo elu na ọkpụrụkpụ nke ụkpụrụ HNT.
Tụkwasị na nke ahụ, ụkpụrụ HNT kwalitere mgbakwunye na mmụba nke mkpụrụ ndụ fibroblast (L929), bụ nke a hụrụ ka ọ na-eto eto n'akụkụ ụrọ nanotube alignment dị ka usoro kọntaktị na-eduzi.Ya mere, usoro dị mfe na ngwa ngwa ugbu a maka ịkwado HNT na ihe ndị siri ike nwere ike ịmepụta matrix na-anabata cell.

Halloysite nanotubes (HNTs) bụ ụrọ nanotubes eke nwere dayameta dị n'èzí nke 50-70 nanometers na oghere dị n'ime nke 10-15 nanometers nwere usoro Al2Si2O5 (OH) 4·nH2O.Otu n'ime ihe dị iche iche nke nanotubes ndị a bụ ihe dị iche iche dị n'ime / mpụta chemical mejupụtara (aluminom oxide, Al2O3 / silicon dioxide, SiO2), nke na-enye ohere mgbanwe nhọrọ ha.
N'ihi biocompatibility na dị nnọọ ala toxicity, ndị a ụrọ nanotubes nwere ike iji na biomedical, ịchọ mma na anụmanụ na-elekọta ngwa n'ihi na ụrọ nanotubes nwere magburu onwe nanosafety na dị iche iche cell omenala.Nanotubes ụrọ ndị a nwere uru nke ọnụ ala dị ala, nnweta sara mbara, yana mgbanwe kemịkalụ dabere na silane dị mfe.
Ntuziaka kọntaktị na-ezo aka n'ihe na-emetụta nghazi cell dabere na usoro geometric dị ka nano/micro grooves na mkpụrụ.Site na mmepe nke injinia anụ ahụ, ihe omume nke njikwa kọntaktị ejirila mee ihe n'ọtụtụ ebe iji metụta morphology na nhazi nke sel.Agbanyeghị, usoro ndu nke njikwa mkpughe ka edobeghị anya.
Ọrụ dị ugbu a na-egosi usoro dị mfe nke nhazi nke mgbanaka nke HNT.Na usoro a, mgbe itinye a dobe nke HNT dispersion na a gburugburu iko slide, HNT dobe na-abịakọrọ n'etiti abụọ kọntaktị na-ebupụta (na slide na magnetik rotor) na-aghọ dispersion na-agafe na capillary.A na-echekwa ma hazie ihe omume ahụ.evaporation nke ihe mgbaze karịa na nsọtụ capillary.
N'ebe a, ike nke na-emepụta site na rotor magnetik na-atụgharị na-eme ka HNT dị na nsọtụ nke capillary na-etinye n'elu ebe na-amị amị n'ụzọ ziri ezi.Ka mmiri na-ekpochapụ, ike kọntaktị karịrị ike pinning, na-agbanye eriri kọntaktị gaa n'etiti.Ya mere, n'okpuru mmetụta synergistic nke ike shear na capillary ike, mgbe mmiri na-ekpochapụ zuru ezu, a na-emepụta usoro mgbanaka osisi nke HNT.
Tụkwasị na nke ahụ, nsonaazụ POM na-egosi nhụsianya pụtara ìhè nke usoro HNT nke anisotropic, nke ihe oyiyi SEM na-ekwu na nkwekọ nke ụrọ nanotubes.
Tụkwasị na nke ahụ, a na-enyocha mkpụrụ ndụ L929 nke a na-emepụta na ụrọ nanotubes nke nwere mgbanaka kwa afọ nwere ọkwa dị iche iche nke HNT dabere na usoro kọntaktị.Ebe, mkpụrụ ndụ L929 gosipụtara nkesa random na ụrọ nanotubes n'ụdị mgbanaka uto na 0,5 wt.% HNT.N'ime ihe owuwu nke nanotubes ụrọ nwere ntinye NTG nke 5 na 10 wt%, a na-ahụ sel elongated n'akụkụ ntụzịaka nke nanotubes ụrọ.
N'ikpeazụ, a na-emepụta mgbanaka mmụba nke macroscale HNT site na iji usoro dị ọnụ ahịa na nke ọhụrụ iji hazie nanoparticles n'usoro.Nhazi nke nhazi nke nanotubes ụrọ na-emetụta nke ukwuu site na ntinye uche HNT, okpomọkụ, ụgwọ elu, nha rotor, na ụda droplet.Ntụle HNT sitere na 5 ruo 10 wt.% nyere ọtụtụ ụdị ụrọ nanotubes a na-enye iwu nke ukwuu, ebe na 5 wt.% ihe ndị a gosipụtara birefringence na agba na-egbuke egbuke.
