Ukucaciswa Komkhiqizo
Ukusebenzisana kweqembu lama-amphiphilic block copolymers we-poly(ethylene oxide) -poly(propylene oxide) -poly(ethylene oxide) (PEO-PPO-PEO) iqembu elinama-molecule ama-molecule amancane angase "ashunwe" ngokuba khona kotshwala obukhethiwe, ukusebenzisana okuqinile okuholela ezinguqukweni ezinkulu (okuxubile) ku-micelle morphology, kuyilapho ukusebenzisana okubuthakathaka kuholela ezinhlotsheni ezikhona zemicelle. Imvelo namandla okusebenzelana phakathi kwe-Pluronic P123 (EO20PO70EO20) kanye nama-molecule amancane asebenza (anionic sodium dodecylsulfate, S411, SDS), (cationic dodecyltrimethylammonium bromide, C12TAB) kanye (non-ionic polyoxyethylene(23)lauryl ether, Brij 35, C12EO23OH) kulindeleke ukuthi kuncike ekuhlukaniseni utshwala obufushane, obuphakathi nobude (ethanol, hexanol kanye ne-decanol ngokulandelanayo) kuphenywa kusetshenziswa i-tensiometry, i-pulsed-gradient spin-echo nuclear magnetic resonance (PGSE-NMR) kanye ne-engeli encane neutron scattering (SANS).Idatha ye-SANS yezisombululo ze-P123 ezinamanzi ezinotshwala obengeziwe yachazwa kahle imodeli eyisiyingi esiyindilinga/igobolondo. ye-micelle morphology.Ukwengezwa kwama-surfactants kuholele ekutheni kube mancane kakhulu, ama-oblate elliptical micelles axubile lapho bungekho utshwala.Ukwengezwa kwe-ethanol kulawa masistimu kuholele ekwehleni kosayizi we-micelle, kuyilapho ama-micelles amakhulu abonwa ekungezweni kotshwala olude.Ucwaningo lwe-NMR lunikeze izilinganiso ezihambisanayo zokwakheka kwe-micelle, kanye nokuhlukaniswa kwezingxenye ezihlukahlukene ku-micelle.
I-4-Nitrophenyl-N-acetyl-β- D-glucosaminide iyi-substrate ewusizo yokuhlolwa kwe-colorimetric okusheshayo komsebenzi we-N-acetyl-b-glucosaminidase kumchamo womuntu.I-Chromogenic β-Glucosaminidase substrate ikhiqiza isixazululo esiphuzi lapho iqhekeka, esetshenziswa ikakhulukazi kumvubelo nezibundi.
