Ngaba ukhe wathatha isitofu se-Pfizer okanye se-Moderna COVID-19 ? Ngoko ke, ngokungazi, uzuze kubuchwepheshe obuphambili kwezonyango. Namhlanje siza kuthetha nge -nanomedicine , enokwenza izinto ezimangalisayo. Nangona igama lisenokuvakala liyinkimbinkimbi kancinci, masilichaze ngokulula, ngolwimi lwethu.
Ngokufutshane, yintoni iNanomedicine?
Khawucinge ngentambo yeenwele zakho. Incinci kangakanani? Ngoku yahlula ububanzi bentambo ngewaka. Leyo yeyona nto incinci, ayibonakali emehlweni, yiyo leyo i-nanometer. Sithetha ngamasuntswana amancinci kangangokuba awanakubonwa ngemakroskopu eqhelekileyo yelabhoratri.
Ngoko ke, i-nanotechnology imalunga nokusebenza ngezinto ezincinci kangaka. I-nanomedicine imalunga nokusebenzisa loo teknoloji ukufumana izisombululo kwiingxaki zethu zempilo.
Ngamafutshane, izazinzulu zenza izixhobo ezincinci kunye nezinto ezinokusebenza kwinqanaba lee-athomu kunye neemolekyuli, iiyunithi ezincinci zesiseko semizimba yethu. Oku kuvumela unyango oluthile , olujolise ngqo . Ngenxa yoko, iziphumo ebezingalindelekanga zinokuncitshiswa kakhulu.
Isebenza njani le nanotechnology?
Cinga ngale ndlela. Masithi ufuna ukuthumela ipasela kumhlobo wakho eColombo. Ungayinika inkonzo yeposi ehambisa ipasela kulo lonke elaseSri Lanka. Emva koko iya kudlula kwiindawo ezahlukeneyo ize ifike kwindawo efanelekileyo.
Okanye, ungaya ngqo endlwini yomhlobo wakho uze uyinike umntu oza kuyizisa iphakheji. Emva koko uza kuyithatha iphakheji uyiyise ngqo kwindawo efanelekileyo, ngaphandle kokuya kwenye indawo, akunjalo?
I-nanomedicine isebenza ngendlela yesibini. Umzekelo, xa unika amayeza omhlaza, ngendlela eqhelekileyo ( i-chemotherapy ), amayeza ahamba emzimbeni wonke. Yiyo loo nto iiseli eziphilileyo zonakala, nto leyo ebangela iziphumo ebezingalindelekanga ezifana nokulahlekelwa ziinwele kunye nokucaphuka .
Kodwa i-nanotechnology inokuhambisa amasuntswana amancinci (ii-nanoparticles) aqulethe amayeza ngqo kwiiseli zomhlaza , njenge-missile ekrelekrele. Oku kuthetha ukuba umonakalo kwiiseli eziphilileyo mncinane kakhulu.
Ziziphi iindlela eziphambili zokusebenzisa i-nanomedicine?
Le teknoloji isekwinqanaba lokuqala, kodwa izazinzulu zikholelwa ukuba iza kuba luncedo kakhulu kwixesha elizayo. Sele kukho iindawo ezininzi eziphambili apho isetyenziswa khona kwaye iphandwa khona.
| Indawo yesicelo | Ingcaciso elula |
|---|---|
| Uxilongo | Ii-nanoparticles zingasetyenziswa kwiimvavanyo zokuskena ezifana ne-MRI kunye ne-Ultrasound ukuze kufunyanwe imifanekiso ecacileyo neneenkcukacha. Oku kwenza kube lula ukufumanisa izifo. |
| Unyango | Ukuhanjiswa kwamayeza okujoliswe kuwo kuvumela ukuba amayeza ahanjiswe ngqo kwiiseli ezinesifo. Kwizitofu ezifana nogonyo lwe-COVID-19, ezi nanoparticles zinceda ukuhambisa ngokukhuselekileyo umyalezo obangela ukuzikhusela komzimba (mRNA) kwiiseli zomzimba. |
| Ukuvuselelwa kwezicubu (i-Regenerative Medicine) | Izinto ezifana neetyhubhu zekhabhoni sele zisetyenziswa ukulungisa izicwili ezonakeleyo. Kwixesha elizayo, obu buchwephesha bunokunceda nokukhulisa kwakhona imithambo-luvo eyonakeleyo. |
| ITheranostics | Le yindlela entsha esekwinqanaba lophando. Apha, zombini ukuxilongwa kunye nonyango zenziwa ngaxeshanye nge-nanoparticle enye. |
Ziziphi izifo eziza kunyangwa yi-nanotechnology kwixesha elizayo?
I-nanomedicine inamandla amakhulu okunyanga ezinye izifo ezininzi ukongeza kumhlaza.
Izifo ze-Neurological
Ingqondo yethu ijikelezwe ngumaleko okhuselayo weeseli. Oku kubizwa ngokuba yiBlood-Brain Barrier (BBB).Oku kuthintela amasuntswana amakhulu ukuba angangeni engqondweni. Oku kwenza kube nzima kakhulu ukuhambisa amayeza kwizifo zengqondo . Kodwa ngenxa yokuba amasuntswana amancinci kakhulu, anokudlula kulo mqobo. Oku kuye kwaphakamisa amathemba amakhulu okunyanga izifo ezifana neethumba zobuchopho, istroke, i-Alzheimer's, kunye ne-meningitis .
Iingxaki Zamehlo
Siyazi ukuba kunzima kangakanani ukunika amayeza emehlweni. Ngenxa yemiqobo yokukhusela emehlweni, amayeza awayi ngqo apho afunekayo khona. Kodwa i-nanotechnology inokuhambisa amayeza kanye apho afunekayo khona. Oku kuya kunceda ekunyangeni iimeko ezifana ne -cataracts, i-glaucoma, kunye nomonakalo kwi-cornea yeliso .
Iintsholongwane
I-nanotechnology inokubona ngokukhawuleza usulelo lweebhaktheriya kwaye ihambise amayeza okubulala iintsholongwane ngqo kwindawo yosulelo. Ingasetyenziselwa ukufaka ii-nanocoats kwizixhobo zesibhedlele ezifana nee-catheters kunye neevalvu zentliziyo ezithintela iibhaktheriya ukuba zinganamatheli.
Ukulimala koMgogodla
Xa intambo yomqolo yonakele, iqala ukusabela kwetyathanga elonakalisa eminye imithambo-luvo. Njengengqondo, intambo yomqolo nayo inomqobo wokukhusela. Ii-nanoparticles zinokunqumla lo mqobo ukuze zihambise amayeza kwaye zithintele ukusasazeka komonakalo. Kwixesha elizayo, izazinzulu zinethemba lokwenza into efana "nee-scaffolds" ezivela kwi-nanomaterials ezikhokela ukukhula kwemithambo-luvo.
Le teknoloji isatshintsha. Mhlawumbi kwiminyaka embalwa ezayo, xa usiya kugqirha wakho, uza kukuxelela ngeyeza okanye unyango olusebenzisa i-nanotechnology. Akuyi kumangaliswa yile nto ke ngoko.
Umyalezo Wokuya Ekhaya
- I-nanomedicine yindlela entsha esebenzisa amasuntswana amancinci ngokuphindwe kangangamawaka kuneenwele zethu ukuxilonga nokunyanga izifo ezingaphakathi emzimbeni.
- Eyona nzuzo inkulu apha kunyango olujoliswe kulo . Oku kuthetha ukuba iyeza lisiwa ngqo kwiiseli ezigulayo, nto leyo enciphisa umonakalo kunye nemiphumo emibi kwiiseli eziphilileyo.
- Sele sibona iziphumo zale ndlela yobuchwephesha kwiigonyo ze-COVID-19 kunye nezinye iindlela zonyango lomhlaza.
- Le teknoloji inamandla amakhulu okubonelela ngezisombululo kwixesha elizayo kwizifo ezininzi ezinzima ukunyangwa, ezifana ne-Alzheimer's, istroke, kunye nokwenzakala komqolo.
- Eli licandelo elikhula ngokukhawuleza. Ukuba ugqirha wakho ukhankanya igama elinxulumene noku, ungoyiki ukucela ingcaciso elula.
