ʻO ka pilina o nā copolymers amphiphilic block o ka poly(ethylene oxide) -poly(propylene oxide) -poly(ethylene oxide) (PEO-PPO-PEO) pūʻulu me nā surfactants liʻiliʻi mole liʻiliʻi hiki ke "hoʻolohe ʻia" e ka hiki ʻana o nā waiʻona i koho ʻia, me nā pilina ikaika e alakaʻi ana i nā loli nui o ka micelle morphology (mixed), ʻoiai nā pilina nāwaliwali e alakaʻi i nā ʻano micelle e noho pū ana. ʻO ke ʻano a me ka ikaika o ka pilina ma waena o Pluronic P123 (EO20PO70EO20) a me nā surfactants liʻiliʻi (anionic sodium dodecylsulfate, SDS, C12SO4Na), (cationic dodecyltrimethylammonium bromide, C12TAB) a me (non-ionic polyoxyethylene(23) lauryl ether, Brij 35, C12EO23OH) ua manaoia e hilinai ia ma ka mahele ana o na kaulahao pokole, waena a me ka loloa (ethanol, hexanol a me decanol). ʻimi ʻia me ka tensiometry, pulsed-gradient spin-echo nuclear magnetic resonance (PGSE-NMR) a me ka neutron scattering liʻiliʻi (SANS). no ka micelle morphology.ʻO ka hoʻohui ʻana o nā surfactants i alakaʻi i ka liʻiliʻi liʻiliʻi, oblate elliptical micelles hui ʻia me ka loaʻa ʻole o nā waiʻona.ʻO ka hoʻohui ʻia ʻana o ka ethanol i kēia mau ʻōnaehana ua alakaʻi i ka emi ʻana o ka nui micelle, ʻoiai ua ʻike ʻia nā micelles nui aʻe i ka hoʻohui ʻia ʻana o nā kaulahao lōʻihi.Hāʻawi nā haʻawina NMR i nā manaʻo koʻikoʻi o ka haku mele, a me ka hoʻokaʻawale ʻana i nā ʻāpana like ʻole i loko o ka micelle.
ʻO 4-Nitrophenyl-N-acetyl-β- D-glucosaminide kahi substrate pono no ka ho'āʻo colorimetric wikiwiki o ka hana N-acetyl-b-glucosaminidase i loko o ka mimi kanaka.ʻO ka substrate Chromogenic β-Glucosaminidase e hāʻawi ana i kahi hopena melemele ma ka ʻoki ʻana, i hoʻohana ʻia i nā mea hū a me nā ʻōpala.
