Ukucaciswa kweMveliso
Ukusebenzisana kwe-amphiphilic block copolymers zepoly(ethylene oxide) -poly(propylene oxide) -poly(ethylene oxide) (PEO-PPO-PEO) iqela elinee-surfactants ezincinci ze-molecule "zinokulungiswa" kubukho beealkoholi ezikhethiweyo, kunye Ukusebenzisana okunamandla okukhokelela kwiinguqu ezinkulu (ezixubileyo) kwi-micelle morphology, ngelixa intsebenziswano ebuthathaka ikhokelela kwiintlobo zemicelle ekhoyo. Ubume kunye namandla onxibelelwano phakathi kwePluronic P123 (EO20PO70EO20) kunye ne-molecule encinci ye-surfactants (i-anionic sodium dodecylsulfate, i-SDS, i-SDS), (cationic dodecyltrimethylammonium bromide, C12TAB) kunye (non-ionic polyoxyethylene (23)lauryl ether, Brij 35, C12EO23OH) kulindeleke ukuba ixhomekeke kulwahlulo lweealcohol ezimfutshane, eziphakathi kunye nexesha elide (ethanol, hexanol kunye ne-decanol ngokulandelelana) iphononongwe kusetyenziswa i-tensiometry, ipulsed-gradient spin-echo nuclear magnetic resonance (PGSE-NMR) kunye ne-angle-angle encinci yokusasazwa kweneutron (SANS) ye-micelle morphology.Ukongezwa kwee-surfactants kukhokelele kuncinci kakhulu, iimicelles ezixubileyo ze-elliptical ngokungabikho kotywala.Ukongezwa kwe-ethanol kwezi nkqubo kukhokelele ekwehleni kwesayizi ye-micelle, ngelixa ii-micelles ezinkulu ziye zabonwa ukongezwa kweealkoholi ezinde.Uphononongo lwe-NMR lubonelele ngoqikelelo oluhambelanayo lokwakheka kweemicelle, kunye nokwahlulwa kwamacandelo ahlukeneyo kwimicelle.
I-4-Nitrophenyl-N-acetyl-β- D-glucosaminide i-substrate eluncedo yovavanyo olukhawulezayo lwe-colorimetric ye-N-acetyl-b-glucosaminidase umsebenzi kumchamo womntu.I-Chromogenic β-Glucosaminidase substrate ivelisa isisombululo esityheli xa siqhekeka, siqeshwe ngokukodwa kwigwele kunye nokungunda.
