Koj puas tau txhaj tshuaj tiv thaiv COVID-19 ntawm Pfizer lossis Moderna? Yog li ntawd koj tsis paub tias koj tau txais txiaj ntsig los ntawm cov thev naus laus zis tshiab hauv kev kho mob. Hnub no peb yuav tham txog nanomedicine , uas tuaj yeem ua tej yam zoo kawg nkaus. Txawm hais tias lub npe yuav suab nyuaj me ntsis, cia peb piav qhia nws yooj yim heev, hauv peb cov lus.
Nanomedicine yog dab tsi, hais yooj yim xwb?
Xav txog ib txoj plaub hau. Nws nyias npaum li cas? Tam sim no faib txoj kab uas hla ntawm txoj plaub hau ntawd los ntawm ib txhiab. Qhov ntawd yog qhov me tshaj plaws, tsis pom rau lub qhov muag liab qab, qhov ntawd yog qhov nanometer. Peb tab tom tham txog cov khoom me me uas lawv tsis tuaj yeem pom nrog lub tshuab kuaj mob hauv chav kuaj.
Yog li ntawd, nanotechnology yog hais txog kev ua haujlwm nrog tej yam ntawm qhov me me. Nanomedicine yog hais txog kev siv cov thev naus laus zis ntawd los nrhiav kev daws teeb meem rau peb cov teeb meem kev noj qab haus huv.
Hais yooj yim xwb, cov kws tshawb fawb tab tom tsim cov khoom siv me me thiab cov khoom siv uas tuaj yeem ua haujlwm ntawm theem ntawm cov atoms thiab molecules, cov chav me tshaj plaws ntawm peb lub cev. Qhov no tso cai rau kev kho mob tshwj xeeb thiab tsom mus rau qhov chaw . Yog li ntawd, cov kev phiv tsis xav tau tuaj yeem txo qis heev.
Cov nanotechnology no ua haujlwm li cas?
Xav txog nws li no. Cia peb hais tias koj xav xa ib pob khoom mus rau ib tug phooj ywg hauv Colombo. Koj tuaj yeem muab pob khoom rau lub tuam txhab xa khoom uas xa thoob plaws Sri Lanka. Tom qab ntawd nws yuav dhau los ntawm ntau qhov chaw thiab mus rau qhov chaw zoo.
Los yog, koj tuaj yeem mus ncaj qha rau koj tus phooj ywg lub tsev thiab muab rau ib tus neeg uas yuav xa pob khoom. Ces koj yuav tau txais pob khoom ncaj qha mus rau qhov chaw zoo, tsis tas yuav mus rau lwm qhov chaw, puas yog?
Tshuaj nano ua haujlwm rau txoj kev thib ob. Piv txwv li, thaum koj muab tshuaj kho mob qog noj ntshav, raws li txoj kev ib txwm muaj ( chemotherapy ), cov tshuaj mus thoob plaws lub cev. Yog vim li cas cov hlwb noj qab haus huv kuj raug puas tsuaj, ua rau muaj kev phiv xws li plaub hau poob thiab xeev siab .
Tiam sis nanotechnology tuaj yeem xa cov khoom me me (nanoparticles) uas muaj tshuaj ncaj qha mus rau cov hlwb qog noj ntshav , zoo li lub foob pob ntse. Qhov no txhais tau tias kev puas tsuaj rau cov hlwb noj qab haus huv tsawg dua.
Cov ntawv thov tseem ceeb ntawm nanomedicine yog dab tsi?
Cov thev naus laus zis no tseem nyob rau theem pib, tab sis cov kws tshawb fawb ntseeg tias nws yuav muaj txiaj ntsig zoo rau yav tom ntej. Twb muaj ntau qhov chaw tseem ceeb uas nws tau siv thiab tshawb fawb.
| Daim teb ntawm daim ntawv thov | Piav qhia yooj yim |
|---|---|
| Kev kuaj mob | Cov nanoparticles siv tau rau hauv kev kuaj mob xws li MRI thiab Ultrasound kom tau txais cov duab meej thiab ntxaws ntxaws. Qhov no ua rau nws yooj yim dua rau kev kuaj mob. |
| Kev Kho Mob | Kev xa tshuaj raws li lub hom phiaj tso cai rau cov tshuaj xa ncaj qha mus rau cov hlwb uas muaj kab mob. Hauv cov tshuaj tiv thaiv kab mob zoo li tshuaj tiv thaiv COVID-19, cov nanoparticles no pab xa cov lus tiv thaiv kab mob (mRNA) mus rau lub cev cov hlwb kom muaj kev nyab xeeb. |
| Kev kho dua tshiab ntawm cov nqaij (Kev kho mob rov qab kho dua tshiab) | Cov khoom siv xws li cov carbon nanotubes twb tau siv los kho cov nqaij uas puas lawm. Yav tom ntej, cov thev naus laus zis no tuaj yeem pab rov qab cog cov hlab ntsha uas puas lawm. |
| Theranostics | Qhov no yog ib txoj kev tshiab uas tseem nyob rau theem tshawb fawb. Ntawm no, ob qho kev kuaj mob thiab kev kho mob raug ua tiav tib lub sijhawm nrog ib lub nanoparticle. |
Cov kab mob twg yuav kho tau los ntawm nanotechnology yav tom ntej?
Nanomedicine muaj peev xwm zoo heev los kho ntau yam kab mob ntxiv rau mob qog noj ntshav.
Cov Kab Mob Hlwb
Peb lub hlwb muaj ib txheej tiv thaiv ntawm cov hlwb. Qhov no hu ua Blood-Brain Barrier (BBB).Qhov no tiv thaiv cov khoom loj loj kom tsis txhob nkag mus rau hauv lub hlwb. Qhov no ua rau nws nyuaj heev rau kev xa cov tshuaj mus rau cov kab mob hauv lub hlwb . Tab sis vim tias cov nanoparticles me me heev, lawv tuaj yeem hla dhau qhov thaiv no. Qhov no tau tsa kev cia siab loj rau kev kho cov kab mob xws li qog hauv lub hlwb, mob stroke, Alzheimer's, thiab mob meningitis .
Teeb meem qhov muag
Peb paub tias nws nyuaj npaum li cas los muab tshuaj rau lub qhov muag. Vim yog cov teeb meem tiv thaiv hauv lub qhov muag, cov tshuaj tsis mus rau qhov chaw uas nws xav tau. Tab sis nanotechnology tuaj yeem xa cov tshuaj mus rau qhov chaw uas nws xav tau. Qhov no yuav pab kho cov mob xws li cataracts, glaucoma, thiab kev puas tsuaj rau lub cornea ntawm lub qhov muag .
Kev kis kab mob
Cov thev naus laus zis nanotechnology tuaj yeem ntes tau cov kab mob sai sai thiab xa cov tshuaj tua kab mob ncaj qha mus rau qhov chaw kis kab mob. Nws kuj tseem siv tau los siv cov txheej nano rau cov khoom siv hauv tsev kho mob xws li catheters thiab lub plawv valve uas tiv thaiv cov kab mob kom tsis txhob lo rau.
Kev Raug Mob Ntawm Qaum Qaum
Thaum cov hlab ntsha hauv lub paj hlwb raug puas tsuaj, nws pib ua ib qho kev sib txuas uas ua rau lwm cov hlab ntsha puas tsuaj. Ib yam li lub hlwb, cov hlab ntsha hauv lub paj hlwb kuj muaj ib qho kev tiv thaiv. Cov nanoparticles tuaj yeem hla qhov kev thaiv no los xa cov tshuaj thiab tiv thaiv kev puas tsuaj kom tsis txhob kis mus. Yav tom ntej, cov kws tshawb fawb vam tias yuav tsim ib yam dab tsi zoo li "scaffolds" los ntawm cov khoom siv nano uas coj kev loj hlob ntawm cov hlab ntsha.
Cov thev naus laus zis no tseem tab tom hloov zuj zus. Tej zaum ob peb xyoos tom ntej no, thaum koj mus ntsib koj tus kws kho mob, nws yuav qhia koj txog cov tshuaj lossis kev kho mob uas siv nanotechnology. Ces koj yuav tsis xav tsis thoob rau qhov no.
