Kev siv cov tshuaj pleev ntsej muag yog ib txoj kev kho mob uas ntau tus neeg siv los tswj kev noj qab haus huv thiab qhov zoo nkauj ntawm lawv cov tawv nqaij. Hauv kev tsim cov tshuaj pleev ntsej muag, cov thev naus laus zis liposome tau dhau los ua qhov tseem ceeb tshiab vim nws muaj peev xwm txhim kho kev nqus cov khoom xyaw nquag mus rau hauv cov txheej tawv nqaij. Tsab xov xwm no yuav tshawb nrhiav cov txheej txheem ntawm kev tsim cov tshuaj pleev ntsej muag siv cov thev naus laus zis liposome, los ntawm cov khoom siv raw mus rau qhov kawg, cov khoom npaj txhij siv.
Liposome yog dab tsi?
Liposomes yog cov vesicles me me, kheej kheej uas muaj ib lossis ntau cov lipid bilayers, uas cia lawv ntim cov khoom xyaw nquag. Liposome technology tau qhia thawj zaug hauv xyoo 1960 thiab tau siv dav hauv ntau qhov chaw, suav nrog cov tshuaj thiab cov tshuaj pleev ib ce. Qhov zoo tshaj plaws ntawm liposomes hauv cov tshuaj pleev ntsej muag yog lawv lub peev xwm los txhim kho kev nkag mus thiab xa cov khoom xyaw nquag mus rau cov txheej tob dua ntawm daim tawv nqaij, khaws cov dej noo, thiab txo qhov khaus.
Cov Khoom Xyaw Xav Tau
1. Cov Khoom Xyaw Lipid:
– Phospholipids: Cov khoom tseem ceeb ntawm liposomes, feem ntau yog los ntawm cov khoom ntuj xws li taum pauv lecithin lossis qe qe.
- Cholesterol: Ntxiv cov roj cholesterol rau hauv cov roj lipid sib xyaw tuaj yeem ua rau kom muaj kev ruaj khov ntawm cov liposomes.
2. Cov Khoom Xyaw Nquag:

Cov Theem Ua Tshuaj Pleev Rau Lub Ntsej Muag Nrog Liposome Technology
1. Kev Npaj Liposome
Kauj Ruam 1: Kev Npaj Cov Tshuaj Lipid
Cov phospholipids thiab cov cholesterol raug sib xyaw nrog cov organic solvent xws li chloroform lossis methanol hauv lub tshuab nqus tsev. Thaum cov khoom sib xyaw ua ke, cov kuab tshuaj yuav raug ua kom qhuav los ua ib txheej nyias ntawm cov lipids ntawm phab ntsa ntawm lub tshuab.
Kauj Ruam 2: Kev Haus Dej
Cov kua lipid ces raug hydrated nrog dej los yog ib qho buffer uas muaj cov khoom xyaw nquag uas tau npaj tseg. Cov txheej txheem no feem ntau ua tiav los ntawm kev siv cov txheej txheem vortexing kom ntseeg tau tias cov lipids yaj sib npaug hauv dej thiab tsim cov liposomal vesicles.
Kauj Ruam 3: Sonication los yog Extrusion
Thaum lub sijhawm ua kom cov dej noo, cov txheej txheem xws li sonication (siv cov suab ultrasonic) lossis extrusion (dhau cov lipids los ntawm daim nyias nyias nrog cov qhov me me) yog siv los txo cov liposomes kom me me lossis me me. Qhov no pab txhim kho kev ruaj khov thiab kev nqus ntawm cov liposomes los ntawm daim tawv nqaij.
2. Ua cov tshuaj pleev kom mos mos
Kauj Ruam 1: Theem Dej
Hauv ib lub thawv sib cais, cov dej uas muaj dej, emulsifier, thiab lwm yam khoom xyaw yaj raug cua sov rau qhov kub txog li 70-80 ° C.
Kauj Ruam 2: Theem Roj
Tib lub sijhawm ntawd, cov roj theem, uas muaj cov roj lipids, cov roj tseem ceeb, thiab lwm yam khoom xyaw uas yaj tau hauv roj, kuj raug cua sov rau tib qhov kub. Cov txheej txheem cua sov no pab ua kom ob theem ua tiav qhov sib xws thaum sib xyaw.
Kauj Ruam 3: Kev sib xyaw ua ke
Cov roj theem raug ntxiv maj mam rau hauv cov dej theem thaum tseem do tas li ntawm qhov ceev ceev. Qhov emulsification no ua rau muaj cov sib tov sib xyaw zoo sib xws thiab sib xws.
3. Kev koom ua ke ntawm Liposomes rau hauv Base Cream
Thaum cov tshuaj pleev thiab liposomes npaj txhij lawm, cov liposomes uas muaj cov khoom xyaw nquag raug ntxiv rau hauv cov tshuaj pleev nrog qeeb qeeb tab sis sib xyaw tas li. Cov txheej txheem no ua kom cov liposomes tau faib sib npaug thoob plaws hauv cov tshuaj pleev yam tsis muaj kev tawg.
4. Ntxiv Cov Khoom Xyaws Ntxiv
Txog rau lub sijhawm no, cov khoom xyaw ntxiv xws li cov tshuaj preservatives, tshuaj tsw qab, thiab xim tuaj yeem ntxiv rau hauv cov mis nyuj. Cov txheej txheem do txuas ntxiv mus kom ntseeg tau tias txhua yam khoom xyaw tau sib xyaw kom huv si.
5. Ntim Khoom
Cov tshuaj pleev uas ua tiav lawm ces muab ntim rau hauv cov thawv uas tau ntxuav kom huv si, npaj txhij rau kev faib tawm. Cov txheej txheem ntim khoom no yuav tsum tau ua tib zoo saib xyuas kom tiv thaiv kev kis kab mob thiab tswj cov khoom kom zoo.
