Nanotechnology: ʻO ka wā e hiki mai ana o ka lāʻau lapaʻau

ʻIke ʻia ka Nanotechnology e hoʻololi i ka lāʻau lapaʻau i ka wā e hiki mai ana. 'O ka hele 'ana i kahi 'a'ohe kanaka i hele ma mua' 'a'ole ia ma ka unahi interstellar wale nō, akā i kēia manawa ma ka unahi microscopic pū kekahi.

He ʻuʻuku loa nā nanoparticles a hiki i nā tausani o lākou ke hoʻokomo i ke poʻo o kahi pine. Hiki i kēia mau ʻāpana liʻiliʻi ke launa pū me nā cell ma ka pae molekala a hiki ke hana i nā hana mana i ka ʻepekema lapaʻau hou.

Aia nā nanomaterials i nā ʻātoma metala, nā ʻātoma non-metal, a me nā ʻāpana ʻāpana a i ʻole semiconducting. ʻO ka hiki o ka nanotechnology ke hoʻoikaika i ka lāʻau i kapa ʻia ʻo "nanomedicine." Ke hoʻohana nei i ka nanomedicine, hiki i nā kauka ke ʻike a mālama i ka maʻi i nā maʻi e loaʻa ana i nā maʻi ākea. Ma ka makahiki 2028, hiki i nā polokalamu nanorobotic programmable a me nā nanopharmaceuticals ke hoʻohuli i nā hopena o ka atherosclerosis a me ka maʻi cardiovascular, ke kōkua ʻana i ka ʻōnaehana pale i ka hakakā ʻana i nā maʻi, ka luku ʻana i nā maʻi kanesa, a me ka hoʻoponopono ʻana i nā hewa genetic i nā cell. ʻO nā makahiki 15-20 e hiki mai ana e hōʻike i kahi lele evolutionary i ka ʻepekema olakino me ke kōkua o ka nanotechnology.

Ua lilo ʻo Nanotechnology i ka lāʻau lapaʻau i mea hoihoi hou no ka ʻepekema hou. Ke alakaʻi nei nā kulanui nui, kekahi me nā ʻoihana pilikino, i nā haʻawina e hōʻoiaʻiʻo ai i ka hoʻomohala ʻana i nā ʻenehana i hiki ke kūlike me ka hiki ʻana mai o ka penicillin. Ke ho'āʻo nei nā kānaka ʻepekema a puni ka honua i ka nanotechnology a me kāna hoʻohana ʻana i ka lāʻau lapaʻau hou. Aia nā haʻawina o kēia manawa i nā nanoparticles a me kāna mau noi i nā ʻenehana lapaʻau, nā ʻenehana diagnostic, nā ʻenehana anti-microbial, a me ka hoʻoponopono kelepona.

Kahaha ua hoʻomohala nā mea noiʻi ma ke Kulanui o Florida i kahi nanoparticle e lanakila ai i ka Hepatitis C, he ma'i ma'i e ho'oulu ai i ka ma'i a me ka cirrhosis o ke ake. ʻAʻole hoʻopau ka mea liʻiliʻi i ka maʻi maʻi, akā hāʻawi i kahi enzyme e pale ai i ka hana hou ʻana o ka maʻi i loko o ke kahe koko o ka mea maʻi me ka ʻole o ka hoʻouka ʻia e ka ʻōnaehana pale. Ua ʻōlelo ka poʻe noiʻi ʻo kā lākou ala e hoʻopau ai i ka maʻi Hepatitis C ma kahi kokoke i 100 pakeneka pono i ka moʻomeheu cell a me nā ʻiole.

Ma ka noiʻi ʻana like ʻole, ʻenehana ma ke Kulanui o Michigan Ke hoʻomohala nei lākou i nā ala e hoʻohana ai i ka nanotechnology i ka hana non-invasive. Manaʻo nā mea noiʻi e hoʻohana i kahi lens me nā nanotubes kalapona e hoʻohuli i ka mālamalama i nā hawewe kani e hiki ke hoʻohana ʻia no ka puhi ʻana i nā maʻi maʻi me ka maʻi kanesa. ʻO ke ʻano o kēia manawa o ka hoʻohana ʻana i nā hawewe kani e puhi i nā pōhaku ʻokiʻoki he mea paʻakikī. Nui loa ka kiko kiko a hiki ke paʻakikī ke hoʻopaʻa i ka ʻiʻo. Me kēia nanotechnology hou, hiki i ke kiko kiko ke hoʻonui i 100 paʻi a hiki i nā kauka ke ʻoki a pahū me ke kaomi wale nō, ʻaʻole paha me ka ʻeha ʻole, no ka mea, ʻoi aku ka maikaʻi o ke kiko kikoʻī e hiki ai ke pale aku i nā aʻalolo. He mea maikaʻi paha kēia ʻano hana ʻoki kino ʻole me ka hōʻino ʻole i ka ʻiʻo olakino.

ʻEpekema Cytimmune, kahi hui nanotech e ulu nei, ke hoʻomohala nei i nā chemotherapeutics e hoʻohana ana i nā nanoparticles gula colloidal liʻiliʻi 27nm e hoʻopaʻa ai i nā maʻi kanesa. Hoʻopili ʻia nā nanoparticles i ka tumor necrosis factor alpha (TNF-a), e kōkua ana i ka luku ʻana i nā cell cancerous, a hāʻawi ʻia i ka ʻōpū. Hoʻemi ʻia nā hopena ʻawaʻawa maʻamau i nā keʻena olakino o ka injection pololei me TNF-a ke uhi ʻia me ka ʻili nanoparticle. Me ka hoʻokomo ʻana o ka TNF-a i uhi ʻia, hiki i nā poʻe maʻi ke hoʻomanawanui i 20 mau manawa o ka maʻamau maʻamau o TNF-a, ʻoiai e hāʻawi ana i nā lāʻau anti-cancer.

Hiki i nā nanoparticles ke hana pū me nā kemika kūlohelohe o ke kino a me ka ʻōnaehana pale e hoʻololi i ka lāʻau lapaʻau. Malia paha e ʻike ka hapa nui o mākou i nā hopena o nanomedicine i ka wā e hiki mai ana. ʻO ka nui o ka hoʻomohala ʻana a me ka noiʻi ʻana i kēia manawa ma nā kulanui like ʻole a me nā hui noiʻi e haʻi mai iā mākou ʻo ka nanotechnology ka wā e hiki mai ana o ka lāʻau lapaʻau a me ke olakino.
