Cov txiaj ntsig ntawm liposomes yog dab tsi?

Dab tsi yog aliposome

Liposomes tam sim no tau kawm dav dav cov neeg nqa khoom nanodrug hauv kev xa tshuaj. Lawv raug kaw vesicles uas muaj lipid bilayer uas muaj phospholipids thiab cov roj cholesterol. Liposomes muaj cov qauv zoo ib yam li cov kab mob lom. Yog li ntawd, liposomes kuj muaj biocompatibility zoo thiab tseem hu ua "artificial biomembranes" thiab "artificial cells".

Cov yam ntxwv ntawm liposomes

Liposomes siv qhov kev sib raug zoo no kom ua tiav cov hom phiaj lossis kev xa tshuaj zoo. Qhov zoo tagnrho liposome yuav tsum muaj cov yam ntxwv ntawm cov ntaub so ntswg zoo sib xws, tsis muaj toxicity, tsim nyog encapsulation muaj peev xwm thiab tso tawm muaj peev xwm.

Hydrophilicity thiab lipophilicity

Vim tias qhov nqus tau qis thiab bioavailability ntawm cov ntsiav tshuaj thiab cov tshuaj ntsiav vim kev noj zaub mov hauv qhov ncauj, lipophilic thiab hydrophilic cov as-ham encapsulated hauv liposomes tuaj yeem hla kev puas tsuaj thiab ncaj qha mus txog cov hnyuv, thiab tuaj yeem thauj mus rau cov hlwb thiab teeb tsa.

Kev kov yeej cov kab mob plab hnyuv

Cov khoom noj khoom haus liposome muaj cov tshuaj tiv thaiv kev noj qab haus huv. Encapsulating bioactive compounds hauv liposomes yog qhov txaus nyiam vim liposomes tau pom tias kov yeej cov teeb meem loj hauv plab hnyuv tom qab kev tswj hwm qhov ncauj ntawm cov tshuaj bioactive.
