Kev khaws cia thiab kev thauj mus los: Cov khoom no tsis muaj kuab lom, nplaim taws rov zoo li qub, raws li kev xa khoom dav dav ntawm cov tshuaj, kaw thiab khaws cia hauv qhov chaw qhuav.

Kev Siv Biomedical

Kev kho mob polyethylene glycol tseem hu ua polyethylene oxide (PEO). Linear polyether tau los ntawm lub nplhaib qhib polymerization ntawm ethylene oxide. Cov ntawv thov tseem ceeb hauv biomedical field muaj raws li hauv qab no:
1. Kev sib chwv lens. Lub viscosity ntawm polyethylene glycol aqueous tov yog rhiab rau shear tus nqi thiab cov kab mob tsis yooj yim loj hlob ntawm polyethylene glycol.
2. Hluavtaws roj nplua nyeem. Ethylene oxide thiab dej ua kom dej polymer. Txhawm rau npaj cov tshuaj pleev cov tshuaj pleev ntawm cov dej-soluble tshuaj, nws kuj tseem siv tau los ua cov kuab tshuaj ntawm acetylsalicylic acid, caffeine, nimodipine thiab lwm yam tshuaj tsis haum rau kev npaj tshuaj.
3. Kev xa tshuaj thiab immobilized enzyme cab kuj. Thaum polyethylene glycol aqueous tov tau lo rau txheej sab nraud ntawm lub ncoo, qhov sib txawv ntawm cov tshuaj hauv cov ntsiav tshuaj tuaj yeem tswj tau qhov ua tau zoo.
4. Kho npoo ntawm kev hloov kho cov ntaub ntawv kho mob polymer. Lub biocompatibility ntawm cov ntaub ntawv kho mob polymer nyob rau hauv kev sib cuag nrog cov ntshav tuaj yeem txhim kho los ntawm adsorption, khaws cia thiab kos duab ntawm amphiphilic copolymer muaj cov polyethylene glycol nyob rau saum npoo ntawm cov ntaub ntawv kho mob polymer.
5. Ua alkanol tshuaj tiv thaiv zaj duab xis.
6. Npaj ntawm hydrophilic anticoagulant polyurethane.
7. Polyethylene glycol 4000 yog ib qho osmotic laxative, uas tuaj yeem nce osmotic siab, nqus dej, mos cov quav, nce ntau, thiab txhawb txoj hnyuv peristalsis thiab tso quav.
8. Cov hniav cuav kho tau. Polyethylene glycol tau siv los ua kev tiv thaiv ntawm cov hniav txhawm kho vim tias nws cov khoom tsis muaj tshuaj lom thiab tawv ncauj.
9. PEG 4000 thiab PEG 6000 feem ntau yog siv los txhawb cov cell fusion lossis protoplast fusion thiab pab cov tsiaj muaj sia (xws li poov xab) nqus DNA thaum hloov. Peg tuaj yeem nqus cov dej hauv cov tshuaj, yog li nws kuj tseem siv los mloog cov kev daws teeb meem.
10. Hauv kev sim ntawm kawm cov qauv molecules, peb tuaj yeem simulate cov chaw muaj neeg coob nyob hauv vivo los xyuas cov cawv ntawm ib puag ncig chaw ntawm cov txheej txheem protein.
