Nyob rau hauv xyoo tsis ntev los no, kev nkag mus thiab cuam tshuam ntawm Nanotechnology rau tshuaj, bioengineering thiab kws muag tshuaj tau tshwm sim. Nanotechnology muaj ib qho IREPLaceable zoo nyob rau hauv lub tsev muag tshuaj, tshwj xeeb tshaj yog nyob rau hauv lub hom phiaj thiab kev kho yeeb tshuaj hauv zos, tawm ntawm kev kho cov protein thiab polypetride

Cov tshuaj nyob rau hauv cov ntaub ntawv siv cov pa tawm tau muab faib rau cov tshuaj feem ntau, thiab cov tshuaj tiv thaiv hauv zos tsis tsuas yog tsis muaj kev cuam tshuam kho mob, nws tseem yuav coj cov teebmeem kev phiv tshuaj tsis zoo, nws tseem yuav coj cov teebmeem kev phiv tshuaj Yog li ntawd, kev txhim kho cov ntaub ntawv tshuaj tshiab tawm tau dhau los ua kev txhim kho ntawm lub tsev muag tshuaj niaj hnub, thiab cov kev tshawb fawb ntawm kev tshawb xyuas tshuaj kho mob hauv chaw muag tshuaj

Piv nrog cov tshuaj kho yooj yim, Nano tshuaj cov tsheb thauj khoom tuaj yeem paub cov tshuaj kho tau. Lub hom phiaj tshuaj xyuas yog hais txog kev xa tshuaj uas pab tau cov ntaub ntawv, ligands lossis cov tshuaj yeeb los sis cov phiaj xwm lossis cov ntshav ncig hauv zos. Nyob rau hauv qhov kev txiav txim ntawm ib qho kev taw qhia kev taw qhia tshwj xeeb, Nano tshuaj cov cab kuj xa cov tshuaj rau cov phiaj xwm tshwj xeeb thiab tawm ntawm cov nyhuv kho. Nws tuaj yeem ua tiav cov tshuaj zoo nrog tsawg dua, cov kev mob tshwm sim tsawg, muaj kev txuag nyiaj ntau, thiab ntev ntev ntawm cov kev xav ntawm lub hom phiaj.

Kev npaj npaj tau yog feem ntau yog cov kws nqa khoom siv ultrorle, uas feem ntau tuaj yeem xaiv cov khoom sib sau ua ke no, thiab lwm yam vim lub cev thiab lub cev. TDDD yog hais txog hom tshuaj tshiab uas muaj peev xwm ua tau thiab cov tshuaj hauv zos hauv cov nqaij mos hauv nroog lossis cov ntshav hauv zos.

Nano tshuaj npaj yog lub hom phiaj. Lawv muaj peev xwm mloog cov tshuaj nyob hauv thaj chaw phiaj xwm nrog kev cuam tshuam me me rau ntawm cov caj pas tsis yog hom phiaj. Lawv tuaj yeem txhim kho kev ua tau zoo tshuaj thiab txo cov kev mob tshwm sim hauv kev phiv. Lawv suav tias yog cov ntaub ntawv ntau tshaj plaws rau kev nqa tshuaj tiv thaiv tshuaj. Tam sim no, qee cov khoom lag luam nano-npaj khoom yog nyob rau ntawm kev ua lag luam nano-npaj yog nyob hauv kev tshawb fawb theem, uas muaj cov kev cia siab hauv cov kev kho mob qog.

Nta ntawm nano-hom phiaj npaj:

Hom Phiaj: Cov tshuaj no muaj cov tshuaj tiv thaiv thaj tsam hauv lub hom phiaj;

⊙ Txo cov tshuaj ntawm cov tshuaj;

⊙ Txhim kho cov nyhuv curative;

⊙ Txo cov kev mob tshwm sim. 

Cov nyhuv ntawm cov nyhuv ntawm lub tsom nano-npaj muaj qhov sib txheeb zoo nrog cov particle loj ntawm kev npaj. Hais nrog qhov loj tsawg dua 100nm tuaj yeem nthuav tawm hauv hlwb pob txha; hais txog 100-200nm tuaj yeem ua rau muaj kev txhawb nqa hauv cov qog ua si; Thaum 0.2-3um uptake los ntawm macrophages hauv tus po; Hais kom cov lus> 7 μm feem ntau yog pov tseg los ntawm lub txaj mob ntsws hws thiab nkag mus rau lub ntsws nqaij lossis alveoli. Yog li ntawd, txawv nano npaj qhia cov teebmeem sib txawv vim qhov sib txawv hauv lub xeev cov tshuaj loj thiab qhov chaw sib txawv. 

Cov thauj khoom uas nquag siv rau kev tsim cov nano-platform rau kev kuaj mob thiab kho mob xws li:

(1) Lipid cov nqa khoom, xws li cov kua dej liposome;

(2) Polymer cov nqa khoom, xws li polymer dendcrimers, micelles, polymer hlentsicles, thaiv copolymers, protein nano hais;

(3) Inoracic cov nqa khoom, xws li nano silicon-raws li cov nanopnetic nanoparticles, hlau nanoparticles, thiab txog-hloov dua siab nanomaterials, thiab lwm yam ..

Cov hauv paus ntsiab lus hauv qab no feem ntau tau ua raws li cov xaiv ntawm Nano Cov Nqa:

(1) Cov khoom siv tshuaj lim dej ntau dua thiab muab cov yam ntxwv tso tawm;

(2) Tsawg txheeb lom zem lom zem thiab tsis muaj kev tiv thaiv kabmob hnyav;

(3) Nws muaj qhov zoo colloidal stability thiab kev ruaj khov ruaj khov;

(4) Kev npaj yooj yim, yooj yim loj-teev ntau lawm, thiab tus nqi qis 

Nano kub hom phiaj kho

Kub (au) nanoparticlesMuaj cov khoom siv hluav taws xob zoo heev thiab kho qhov muag khoom, uas tuaj yeem siv tau zoo siv hauv kev tsom ntsuas hluav taws xob. Los ntawm kev tsim qauv zoo, nano kub hais tau nthuav tawm cov nqaij nqaij qog zoo. AU nanoparticles tuaj yeem txhim kho qhov hluav taws xob kev ua tau zoo hauv thaj chaw no, thiab tseem tuaj yeem hloov kho qhov teeb meem teeb meem lub teeb rau hauv tshav kub kom tua cov kabmob kheesxaws hauv thaj chaw. Nyob rau tib lub sijhawm, cov tshuaj nyob rau ntawm Nano Au hais kuj tseem tuaj yeem tso tawm hauv thaj chaw, txuas ntxiv txhim kho cov nyhuv kho. 

Nanoparticles tseem yuav tsom lub cev. Nanopowders npaj txhij npaj los ntawm qhwv cov tshuaj thiab siv cov khoom siv sib nqus hauv vitro los coj cov kev taw qhia thiab hauv zos ntawm cov tshuaj hauv lub cev. Cov tshuaj sib nqus uas nquag siv, xws li Fe₂O₃, tau kawm los ntawm conjugating mitoxantrone nrog Dextran thiab tom qab ntawd qhwv lawv nrog FE₂O₃ los npaj nanoparticles. Cov kev sim ua tshuaj uas tau ua tiav hauv cov nas. Cov txiaj ntsig tau pom tias cov tshuaj uas muaj peev xwm tiv thaiv nanoparticles tuaj yeem tuaj yeem tuaj yeem tuaj yeem thiab nyob hauv cov qog nqaij hlav yog siab dua li cov ntaub so ntswg thiab cov ntshav.

Fe₃O₄tau ua pov thawj yuav tsis muaj tshuaj lom thiab biocompible. Raws li cov khoom siv tshwj xeeb, tshuaj lom neeg, cov khoom siv hluav taws xob, xws li kev tshawb fawb ntawm tes oxiaxy oxide Cov nqaij mos kho; kev xa tshuaj; Nuclear Sib Nqus Kev Ua Haujlwm; Hypertherman kev kho mob cancer hlwb, thiab lwm yam.

Cov Nanotubes (CNTs)Muaj cov qauv hollow thiab sab nraud diameters, uas tuaj yeem tsim cell generation muaj peev xwm thiab tuaj yeem siv ua yeeb tshuaj nanocarters. Ib qho ntxiv, cov nanotubes tseem muaj cov haujlwm ntawm kev kuaj mob qog thiab ua si lub luag haujlwm zoo hauv kev kos cim. Piv txwv li, cov pa roj carbon nanotubes ua lub luag haujlwm ntawm kev tiv thaiv cov qog sib txuas lus thaum phais qog. Nws kuj tseem siv tau los ua tus cim ntawm cov qog nqaij qog noj tshuaj, thiab muaj cov haujlwm qeeb tawm rau kev tiv thaiv kev tiv thaiv thiab kho mob cancer metastasis.

Txhawm rau suav, daim ntawv thov ntawm Nanotechnology hauv daim teb ntawm cov tshuaj thiab lub tsev muag tshuaj muaj tseeb nyob rau hauv kev txhim kho tib neeg kev noj qab haus huv thiab lub neej zoo.
