Mafotokozedwe a Zamalonda
Kuyanjana kwa amphiphilic block copolymers a poly(ethylene oxide) -poly(propylene oxide) -poly(ethylene oxide) (PEO-PPO-PEO) gulu lokhala ndi mamolekyu ang'onoang'ono okhala ndi mamolekyu ang'onoang'ono akhoza "kusinthidwa" ndi kupezeka kwa mowa wosankhidwa, ndi Kuyanjana kwamphamvu kumabweretsa kusintha kwakukulu mu (osakanikirana) ma morphology a micelle, pomwe kusagwirizana kofooka kumabweretsa mitundu yokhazikika ya micelle. (cationic dodecyltrimethylammonium bromide, C12TAB) ndi (non-ionic polyoxyethylene(23)lauryl ether, Brij 35, C12EO23OH) akuyembekezeka kudalira kugawa kwa mowa waufupi, wapakatikati ndi wautali (ethanol, hexanol ndi decanol motsatana) kufufuzidwa pogwiritsa ntchito tensiometry, pulsed-gradient spin-echo nuclear magnetic resonance (PGSE-NMR) ndi nyutroni yaing'ono yaing'ono (SANS). Deta ya SANS ya mayankho amadzi a P123 okhala ndi mowa wowonjezera inafotokozedwa bwino ndi chitsanzo cha spherical core/chipolopolo kwa micelle morphology.Kuphatikiza kwa ma surfactants kunapangitsa kuti pakhale ma micelles ang'onoang'ono, oblate osakanikirana popanda mowa.Kuphatikizika kwa ethanol kumakinawa kunapangitsa kuti kukula kwa micelle kuchepe, pomwe ma micelles akuluakulu adawonedwa pakuwonjezera mowa wautali.Kafukufuku wa NMR adapereka kuyerekezera kowonjezera kwa kapangidwe ka micelle, komanso kugawa magawo osiyanasiyana kukhala micelle.
4-Nitrophenyl-N-acetyl-β- D-glucosaminide ndi gawo lothandiza lachidziwitso chofulumira cha colorimetric cha ntchito ya N-acetyl-b-glucosaminidase mu mkodzo waumunthu.Chromogenic β-Glucosaminidase gawo lapansi lomwe limatulutsa chikasu pa cleavage, lomwe limagwiritsidwa ntchito makamaka mu yisiti ndi nkhungu.
