Hiki i ka hoʻohui ʻana o nā nanoparticles ke hoʻomaikaʻi i ka hana o nā uhi kuʻuna a hoʻomākaukau paha i nā uhi nano hana hou. Hiki i nā uhi nano hana hou ke hāʻawi i nā lole i nā hana maikaʻi a hoʻohana nui ʻia i ka paʻi lole a me ka hana hoʻoluʻu.

Nā uhi nano hoʻoluʻu hoʻoluʻu wela

Hiki i nā lole hoʻopaʻa wela ke hōʻoluʻolu pono i ka ʻeha o ka poʻe i hoʻokumu ʻia e ka lōʻihi o ka hoʻolaha ʻana i ka lā a i ʻole ke kaiapuni wela kiʻekiʻe, e hana ana i kahi hopena pale maikaʻi aʻe ma ke kino o ke kanaka. ʻO ka uhi hoʻopaʻa wela nanometer ke ʻano maʻamau i hoʻohana ʻia e hoʻomākaukau i nā lole hoʻopaʻa wela. Hiki i nā uhi nanometer hana ke hoʻomaikaʻi pono i ka hana hoʻopaʻa wela a me ka hoʻomaʻalili ʻana o nā lole.

Uhi wai ʻole nano

ʻO ka hoʻomākaukau ʻana i ka lole pale wai, ʻo ia ka hoʻohui ʻana i kahi uhi pale wai ma luna o ka ʻili o ka lole. Hoʻohana ʻia ka waiwai pale wai maikaʻi loa o ka uhi ʻana e hāʻawi i ka lole i kahi hana pale wai. Eia nō naʻe, ʻaʻole paʻa ka waiwai pale wai o ka lole i uhi ʻia i hana ʻia me ka uhi pale wai kuʻuna a he paʻa ʻole. Inā lōʻihi ka manawa o ka lole i loko o kahi aniau pulu (e like me ka hele wāwae ʻana i waho i ka lā ua no ka manawa lōʻihi), he mea nui loa ia e hōʻoia i ka hana pale wai maikaʻi a paʻa o ka lole. ʻO ka hui pū ʻana o nā nanomaterials a me nā uhi e hoʻomaikaʻi ai ka uhi pale wai i kāna hana pale wai a me ke kūpaʻa i kekahi ʻano.

Pena nano antibacterial

I kēia manawa, ʻo nā uhi nano antibacterial i oʻo loa ʻia he mau uhi nano TiO2, nona ke ʻano antibacterial e pepehi a kāohi paha i ka ulu ʻana o nā microorganism ma o ka hoʻohana ʻana i nā ʻano oxygen reactive a me nā radical free i hana ʻia e nā ʻano oxidation photocatalytic o nano TiO2. Ua hoʻomākaukau ʻo Xu Ruifen et al. i ka uhi antibacterial ma ka hoʻopuehu ʻana i ka nano-meter TiO2 ma hope o ka mālama ʻana i ka ʻili i loko o ka phenylpropyl emulsion a ua hana i ka hoʻāʻo hopena antibacterial. Ua hōʻike nā hopena he ʻoi aku ka nui o ka pepehi ʻana o ka uhi antibacterial ma mua o 99% no Staphylococcus aureus, Escherichia coli, Bacillus subbacillus, etc., me ka hopena bactericidal ikaika a me ka hopena antibacterial lōʻihi.

Pēlā nō, hiki ke hoʻokaʻawale ʻia ka nano-znO e hana i nā hui electron-hole ma lalo o nā kūlana mālamalama, a hoʻohui i ka oxygen a i ʻole ka wai i ka lewa e hana i nā ʻano oxygen reactive a me nā radical free, hiki ke pepehi i ka hapa nui o nā bacteria a me nā virus.

ʻĪnika pena nano no ka paʻi ʻīnika

He hana paʻi lole ʻīnika ʻaʻohe pili, kiko matrix, maʻemaʻe a aloha i ke kaiapuni ka paʻi ʻana i nā ʻīnika dye i hoʻohana ʻia i ka paʻi ʻīnika dye kikohoʻe o nā lole, he haʻahaʻa ka paʻa o ka mālamalama, lōʻihi ke kaʻina hana a me ka haumia o ke kaiapuni, no laila he paʻakikī ke hoʻolaha a hoʻopili. E pili ana i ka ʻīnika dye, he ʻano like ko ka ʻīnika pena, he maʻalahi ka hana lima, ʻaʻole e hana i ke kala lana a ʻoi aku ka nui o nā pono, e like me ka palekana o ke kaiapuni, akā i kēia manawa ʻoi aku ka maikaʻi ʻole o ka hana uhi ʻīnika lole kūloko a me ke kūpaʻa o ka ʻīnika, ʻaʻole i lawa nā waiwai o ka paʻi ʻana i nā lole, e like me ke kūpaʻa wai, kū i ka hamo pulu, he mea nui kēia mau mea i ka hoʻolaha nui ʻana o ka ʻenehana paʻi ʻīnika.
