Nā Noi Biomedical o Nanotechnology: Nā Hana Hou e Hoʻololi nei i ke ʻAno o ka Mālama Ola
ʻO ka Nanotechnology, kahi lālā o ka ʻepekema e kālele ana i ka hoʻopunipuni ʻana i nā mea ma ka pae nanometer (hoʻokahi piliona o ka mika), ua wehe i nā hiki kipi ma nā ʻano like ʻole, me ka biomedicine. Loaʻa nā noi biomedical o ka nanotechnology mai nā hōʻoia pololei a hiki i nā lāʻau lapaʻau ʻoi aku ka maikaʻi a me nā lāʻau lapaʻau pilikino. E nānā kēia ʻatikala i nā noi koʻikoʻi o ka nanotechnology i ka biomedicine , pehea e hana ai kēia ʻenehana, a me kona hopena i ka wā e hiki mai ana o ke olakino honua.
Nā ʻike nano
ʻO Nanodiagnostics e pili ana i ka hoʻohana ʻana i nā loina a me nā ʻenehana nanotechnology no ka ʻike ʻana i nā maʻi. ʻO kahi laʻana e ʻike nui ʻia nei, ʻo ia ka hoʻohana ʻana i nā nanoparticles i ka ʻike ʻana i ke kanesa. Hiki ke hana ʻia nā nanoparticles me nā waiwai kikoʻī e hiki ai iā lākou ke nakinaki i nā hunaola kanesa kikoʻī. ʻAe kēia i nā mea noiʻi a me nā kauka lapaʻau e ʻike pololei i ke alo a me ka nui o nā ʻōpū, pinepine i kahi pae mua ma mua o nā ʻano maʻamau.
Ua ʻike ʻia he kūpono loa nā ʻano hana e like me nā kiko quantum, nā nanostructures liʻiliʻi hiki ke lepili ʻia me nā biomolecules kikoʻī, i ka ʻike ʻana i nā biomarkers kikoʻī. Ua hoʻolalelale pū ka hoʻomohala ʻana o nā biosensors e pili ana i ka nanotechnology i ka ʻike ʻana i nā maʻi lele , e like me ka HIV a me ka maʻi puʻupuʻu, ma ka hōʻoia ʻana i ka ʻike ʻana o nā pathogens ma nā ʻano haʻahaʻa loa.
Hoʻōla i kuhikuhi ʻia
ʻO kekahi o nā hoʻohana koʻikoʻi o ka nanotechnology i ka lāʻau lapaʻau ʻo ia ka hiki ke hāʻawi i ka lāʻau lapaʻau i kuhikuhi ʻia. I ka lāʻau lapaʻau maʻi kanesa, no ka laʻana, hiki ke hana ʻia nā nanoparticles e ʻike a hāʻawi pololei i nā lāʻau lapaʻau i nā hunaola kanesa, e hōʻemi ana i ka hōʻino ʻana i nā ʻiʻo olakino. Hoʻonui kēia i ka pono o ka lāʻau lapaʻau a hōʻemi i nā hopena ʻaoʻao, kahi pilikia nui i nā lāʻau lapaʻau maʻamau.
ʻO Liposomes kahi ʻano nanoparticle i hoʻohana ʻia i ka lāʻau lapaʻau i kuhikuhi ʻia. ʻO Liposomes nā vesicles lipid nanoscale e hiki ke lawe i nā lāʻau lapaʻau i loko o ke kino, pale iā lākou mai ka palaho ʻana, a hāʻawi pololei iā lākou i nā wahi maʻi. Eia kekahi, ua noiʻi nui ʻia nā nanoparticles polymer a me nā nanocarriers inorganic, e like me ke gula a me ke kālā nanoparticles, a ke hoʻomohala ʻia nei no nā noi lapaʻau.
Nā lāʻau lapaʻau antimicrobial a me ka lawe ʻana i nā gene
Hāʻawi pū ka Nanotechnology i ka manaʻolana hou i ka hoʻomohala ʻana i nā mea antimicrobial a me ka gene therapy. Ua hoʻohana ʻia nā ʻili nanoparticle e pepehi i ka bacteria a hoʻopilikia paha i nā biofilms bacteria i kū i nā antibiotics maʻamau. No ka laʻana, ua ʻike ʻia nā nanoparticles kālā he hana antimicrobial ikaika a ua loaʻa nā noi lapaʻau ākea.
Ma ke ʻano o ka hoʻōla ʻana o nā genes, hiki ke hoʻohana ʻia nā nanoparticles ma ke ʻano he vectors e hoʻouna i nā genes therapeutic i loko o nā cell. Hōʻike kēia i kahi hopena kūpono no nā ʻano maʻi genetic like ʻole i nele i nā lāʻau lapaʻau kūpono i kēia manawa. ʻO Lipofection, kahi ʻenehana e hoʻohana ana i nā liposomes e hoʻouna i ka DNA a i ʻole RNA, ʻo ia kekahi laʻana o ke ʻano e hiki ai i ka nanotechnology ke kōkua i ka hoʻokomo pono ʻana i nā mea genetic i loko o nā cell target.
Nā Implants a me nā Protheses Maikaʻi
Ua hoʻololi ka nanotechnology i ke ʻano o kā mākou hana ʻana a me ka hoʻohana ʻana i nā implants lapaʻau a me nā prostheses. Me nā uhi nanoparticle, hiki ke hoʻolālā ʻia nā implants e ʻoi aku ka paʻa, ʻoi aku ka biocompatible, a loaʻa nā waiwai antimicrobial. Ke ʻimi ʻia nei hoʻi nā nanomaterials i hana ʻia e like me nā nanotubes carbon a me graphene e hoʻomaikaʻi i ka ikaika a me ka hana o nā prostheses.
Kōkua kēia mau nanonetworks i ka hōʻole ʻana o ke kino i nā implants, hoʻemi i ka pilikia o ka maʻi, a paipai i ka ho'ōla ʻana. No ka laʻana, hiki i nā nanonetworks ma luna o ka ʻili o nā implants iwi ke paipai i ka ulu wikiwiki a me ka ikaika o ka iwi hou a puni ka implant.
Nā Hōʻoia Kiʻi
He kuleana koʻikoʻi ko ka Nanotechnology i ke kiʻi ʻana i nā kiʻi lapaʻau. Hiki ke hoʻonui ʻia nā ʻano hana e like me ke kiʻi ʻana i ka resonance magnetic (MRI) a me ka positron emission tomography (PET) ma o ka hoʻohana ʻana i nā nanoparticles. No ka laʻana, hiki ke hoʻohana ʻia nā nanoparticles iron oxide ma ke ʻano he mea hoʻohālikelike no ka MRI, e ʻae ana i nā kiʻi maopopo a kikoʻī hoʻi o nā ʻano anatomical kūloko.
Hiki i nā nanoparticles i hui pū ʻia me nā mea hana kiʻi ke kōkua i ka ʻike ʻana i ka maʻi i nā pae mua a me ka ʻike nui aʻe. He mea nui loa kēia i ka oncology, kahi e hiki ai i ka ʻike mua ke hoʻomaikaʻi nui i ka prognosis a me nā koho lapaʻau.
Nā lāʻau pale a me nā Nanovaccines
He kuleana koʻikoʻi nō hoʻi ka Nanotechnology i ka hoʻomohala ʻana a me ka hoʻonui ʻana i nā lāʻau pale . Kū pinepine nā lāʻau pale kuʻuna i nā pilikia e like me ka haʻahaʻa o ka pono a me nā pilikia kūpaʻa. Hoʻohana nā Nanovaccines i nā nanoparticles e hāʻawi i nā antigens a hoʻonui i ka pane pale o ke kino. Hiki i kēia ke hoʻonui i ka pono o ka lāʻau pale a hōʻemi i ka pono no nā adjuvants ʻawahia.
No ka laʻana, ua hoʻohana ʻia nā lipid nanoparticles (LNPs) i kekahi mau lāʻau pale COVID-19 e hāʻawi i ka messenger RNA (mRNA) i loko o nā ʻāpana o ke kino e kuhikuhi iā lākou e hana i nā protein e hoʻoulu ai i kahi pane pale.
Palekana a me ke Kānāwai
Ma mua o ka hoʻohana piha ʻia ʻana o ka nanotechnology i ka lāʻau lapaʻau, pono e loiloi pono ʻia nā pilikia palekana. He kū hoʻokahi nā nanoparticles a hiki ke hōʻike i nā ʻano toxicological like ʻole i hoʻohālikelike ʻia me ka mea like ma kona ʻano macroscopic. No laila, he mea koʻikoʻi ka noiʻi ʻana i ka biocompatibility, ka hoʻolaha ʻana o ke kino, ka metabolism, a me ka excretion o nā nanoparticles.
Eia kekahi, pono nā lula a me nā kūlana paʻa e hōʻoia i ka palekana a me ka pono o nā huahana nanotechnology. Ke hana nei nā keʻena hoʻoponopono e like me ka Food and Drug Administration (FDA) ma ʻAmelika Hui Pū ʻIa a me ka European Medicines Agency (EMA) ma ʻEulopa e hana i kahi ʻōnaehana hoʻoponopono kūpono no nā noi nanotechnology i ka lāʻau lapaʻau.
ʻO ka wā e hiki mai ana o ka Nanotechnology ma Biomedicine
He mea hoʻohiki nui ka wā e hiki mai ana o ka nanotechnology i ka biomedicine a manaʻo ʻia e hoʻololi i ke ʻano o kā mākou hoʻokokoke ʻana i ka ʻike ʻana i nā maʻi, ka mālama ʻana, a me ka pale ʻana . E hiki ai i kēia ʻenehana ke hana i nā lāʻau lapaʻau pilikino a maikaʻi hoʻi, i hana ʻia i nā ʻano kūikawā o nā maʻi.
ʻO ka hoʻomohala hou ʻana i kēia kahua hiki ke alakaʻi i ka hoʻokumu ʻana o nā ʻenehana hou a mākou i noʻonoʻo ʻole ai. ʻO ka noiʻi hoʻomau a me ka laulima ʻana ma waena o nā aʻo e like me ka biology, kemika, physics, a me ka ʻenekinia e lilo i mea nui no ka hoʻokō ʻana i ka hiki piha o ka nanotechnology i ka biomedicine.
Ka hopena
Hāʻawi ka Nanotechnology i nā ʻano noi like ʻole i ka biomedicine . Mai nā nanodiagnostics wikiwiki a pololei hoʻi, a hiki i nā lāʻau lapaʻau i ʻoi aku ka maikaʻi me nā hopena ʻaoʻao liʻiliʻi, a hiki i ka hoʻomohala ʻana i nā implants a me nā prostheses i hoʻomaikaʻi ʻia a biocompatible, loaʻa i ka nanotechnology ka hiki ke hoʻololi i ka mālama ola honua. Ke hoʻomau nei mākou e ʻimi a hoʻohana i kēia ʻenehana, he mea nui ia e hōʻoia i kona hoʻohana palekana a maikaʻi hoʻi ma o ka noiʻi piha a me nā hoʻoponopono koʻikoʻi. Ke nānā aku nei ka wā e hiki mai ana o ka nanotechnology i ka biomedicine, a aia wale nō mākou i ka hoʻomaka ʻana o ka mea hiki ke lilo i kipi nui i ka mālama ola.
