Tilmaamaha Alaabta
Is dhexgalka amphiphilic block copolymers of poly (ethylene oxide) -poly (propylene oxide) -poly (ethylene oxide) (PEO-PPO-PEO) kooxda leh surfactants molecule yar yar waxaa laga yaabaa in "la habeeyey" by joogitaanka khamriga la doortay, iyadoo is dhexgalka xooggan ee keenaya isbeddello la taaban karo oo ku yimaada qaab-dhismeedka micelle, halka isdhexgalka daciifka ahi uu keeno noocyada micele ee wada nool.Dabeecada iyo xoogga isdhexgalka ka dhexeeya Pluronic P123 (EO20PO70EO20) iyo surfactants molecule yar yar (anionic sodium dodecylsulfate), S4Na12 (cationic dodecyltrimethylammonium bromide, C12TAB) iyo (non-ionic polyoxyethylene (23) lauryl ether, Brij 35, C12EO23OH) ayaa la filayaa inay ku xiran tahay qaybinta ee khamriga silsilad gaaban, dhexdhexaad ah iyo dheer (ethanol, hexanol iyo decanol siday u kala horreeyaan) baadhista iyadoo la isticmaalayo tensiometry, pulsed-gradient spin-echo nukliyeerka magnetic resonance (PGSE-NMR) iyo firdhinta neutron-ka yar (SANS) ee micele morphology.Ku darida surfactants-ku waxay keentay inay si aad ah u yareeyaan, jiirka isku dhafan ee elliptical-ka ah ee maqnaanshaha khamriga.Ku darida ethanol ee nidaamyadan waxay keentay hoos u dhac ku yimid cabbirka micelle, halka jiirarka waaweyn la arkay markii lagu daray aalkolada silsiladda dheer.Daraasadaha NMR waxay bixiyeen qiyaaso dhammaystiran oo ka kooban micele, iyo u qaybinta qaybaha kala duwan ee micele.
4-Nitrophenyl-N-acetyl-β- D-glucosaminide waa substrate faa'iido u leh baaritaanka midabada degdega ah ee N-acetyl-b-glucosaminidase dhaqdhaqaaqa kaadida aadanaha.Substrate-ka Chromogenic β-Glucosaminidase oo soo saara xal huruud ah marka la dillaaco, gaar ahaan ka shaqeeya khamiirka iyo caaryada.
