Tlhaloso ea Sehlahisoa
Tšebelisano ea li-amphiphilic block copolymers tsa poly(ethylene oxide) -poly(propylene oxide) -poly(ethylene oxide) (PEO-PPO-PEO) sehlopha se nang le li-surfactants tse nyane tsa limolek'hule li ka "lokisoa" ka boteng ba lino tse tahang tse khethiloeng, Litšebelisano tse matla tse lebisang liphetohong tse kholo ho (motsoako) morphology ea micelle, ha litšebelisano tse fokolang li lebisa mefuteng e mengata ea micelle. (cationic dodecyltrimethylammonium bromide, C12TAB) le (non-ionic polyoxyethylene(23)lauryl ether, Brij 35, C12EO23OH) e lebelletsoe ho its'etleha ka karohano ea li-alcohol tse khutšoane, tse mahareng le tse telele (ethanol, hexanol le decanol ka ho latellana) phuputso ka ho sebelisa tensiometry, pulsed-gradient spin-echo nuclear magnetic resonance (PGSE-NMR) le small-angle neutron scattering (SANS).The data SANS for aqueous P123 solutions with add alcohols were cribed well by a charged spherical core/shell model. bakeng sa morphology ea micelle.Ho eketsoa ha li-surfactants ho lebisitse ho li-micelles tse nyane haholo, tsa oblate elliptical tse tsoakiloeng ha ho se na joala.Keketso ea ethanol lits'ebetsong tsena e lebisitse ho fokotseha ha boholo ba micelle, athe li-micelles tse kholo li ile tsa bonoa ha ho eketsoa lino tse tahang tsa ketane e telele.Lithuto tsa NMR li fane ka likhakanyo tse tlatsanang tsa sebopeho sa micelle, le karohano ea likarolo tse fapaneng ho micelle.
4-Nitrophenyl-N-acetyl-β- D-glucosaminide ke substrate e molemo bakeng sa tlhahlobo ea colorimetric e potlakileng ea mosebetsi oa N-acetyl-b-glucosaminidase morong oa motho.Chromogenic β-Glucosaminidase substrate e fana ka tharollo e mosehla ha e petsoha, e sebelisoang haholo-holo tomoso le hlobo.
