ka taea te centrifugation motuhake i ngā nanoparticles wairewa
Kupu Whakataki
He tikanga whānui te whakamahi i te centrifugation i roto i te ao o te nanotechnology hei wehewehe i ngā matūriki nano i runga i ō rātou āhuatanga, pērā i te rahi, te āhua, me te mātotoru. He wero motuhake ngā matūriki nano wairewa nā te mea he kaha ki te wairewa, ki te marara rānei i roto i te wai. Ka rukuhia e tēnei tuhinga te whakamahinga o te centrifugation i roto i te wehenga o ngā matūriki nano wairewa, ā, ka tūhuratia ngā rautaki rerekē e whakamahia ana hei whakatutuki i te wehenga whai hua.
Te Mārama ki te Whakapūngao
Ko te centrifugation he tukanga e whakamahi ana i te kaha centrifugal hei wehewehe i ngā matūriki i roto i te ranunga rerekē. Ko te huri i te tauira i ngā tere teitei, ka waiho ngā matūriki kia pupū ake i runga i tō rātou taumaha. Ko te mātāpono o te centrifugation ko te tere o te taunga o ngā matūriki matotoru, ka hanga he pirepire ki raro o te ngongo, ko ngā matūriki māmā ake ka noho tonu ki roto i te wai i roto i te wai.
1. Ngā Tikanga Whakapūmau Tuku Iho
I roto i te horopaki o te wehewehe i ngā matūriki nano wairewa, kāore pea ngā tikanga whakaterenga tuku iho e hua mai he hua pai. Nā te mea ka memeha, ka marara rānei ngā matūriki nano wairewa i roto i te wai, ka uaua pea te whakatōtika i a rātou. Heoi, he maha ngā whakarerekētanga ki ngā tikanga whakaterenga tuku iho kua whakawhanakehia hei whakatika i tēnei take.
2. Te Whakapūtanga o te Rerekētanga Kiato
Ko te whakapūtanga i te pikinga matotoru he tikanga e whakamahia whānuitia ana hei wehewehe i ngā matūriki he rite te matotoru. Mō ngā matūriki nano wairewa, ka taea te whakarite i te reo matotoru kia rite ki te matotoru e hiahiatia ana o ngā matūriki ūnga. Mā te whakatakoto āta i te tauira ki runga i te pikinga matotoru kua oti te hanga, ka taea te wehewehe i ngā matūriki nano kia rite ki ō rātou matotoru i a rātou e heke ana ki ō rātou tūranga taurite i roto i te reo.
3. Te Whakamātautau Rahi-Whakakore (SEC)
Ko te Size-Exclusion Chromatography (SEC), e mōhiotia ana ko te gel filtration chromatography, he tikanga rongonui e whakamahia ana hei wehewehe i ngā ngota ngota, i ngā matūriki rānei i runga i tō rātou rahi. Mō ngā nanoparticles wairewa, ka taea te whakarerekē i te SEC hei wehewehe pai i ngā nanoparticles i runga i tō rātou rahi wai. Ka uru ngā nanoparticles iti ki roto i ngā pūwero o te wāhanga tūmau, ka roa ake te wā pupuri, ko ngā nanoparticles nui ake ka tere ake te mimiti.
4. Te Whakapūngao-ā-Ura
Ko te ultracentrifugation he momo centrifugation matatau e whakamahi ana i ngā tere teitei ake me ngā wā oma roa atu i ngā huarahi tuku iho. Ka taea te whakamahi i tēnei tikanga hei wehewehe i ngā matūriki nano wairewa mā te whakarerekē i te kaha centrifugal e whakamahia ana me te arotau i te wā oma. Mā te kimi i ngā āhuatanga tino pai, ka taea te wehewehe pai i ngā matūriki nano wairewa i runga i ō rātou tauwehenga whakatō, ka taea ai te kohikohi pai i ngā matūriki nano kua tohua.
5. Te Whakapūtanga Iti-Rōrahi-Kiato
Ka whakakotahi te ultracentrifugation mā te mātotoru-rōrahi i ngā mātāpono o te centrifugation mātotoru me te ultracentrifugation hei wehewehe i ngā matūriki wairewa. Ka whakatūhia he mātotoru mātotoru mā te whakamahi i tētahi reo e tika ana, ā, ka whakatakotoria te tauira ki runga. Kātahi ka mahia te ultracentrifugation hei wehewehe i ngā matūriki i runga i tō rātou mātotoru me te whakatutuki i te wehewehenga taumira teitei. Mā tēnei tikanga ka taea te wehewehe tika i ngā rahi rerekē, i ngā momo rānei o ngā matūriki i roto i te āhua wairewa.
Whakamutunga
Kua kitea te whai huatanga o ngā tikanga whakapūtāhui i roto i te wehenga o ngā matūriki nano, tae atu ki ngā matūriki nano wairewa. Mā te whakarerekē i ngā huarahi whakapūtāhui tuku iho, kua taea e ngā kairangahau te wikitoria i ngā wero e pā ana ki te wairewa o ngā matūriki nano, me te whakatutuki i te wehenga whai hua. Ko te whakapūtāhui i te pikinga matotoru, te chromatography whakakore-rahi, te whakapūtāhui ultra, me te whakapūtāhui ultra-pikinga matotoru kei roto i ngā rautaki rerekē e whakamahia ana hei wehewehe i ngā matūriki nano wairewa. Mā ēnei tikanga ka whakatakoto i te ara mō ngā whanaketanga me ngā tono o te hangarau nano i roto i ngā mara rerekē mai i te rongoā ki te pūtaiao taiao.
