Kudyidzana kweamphiphilic block copolymers epoly(ethylene oxide) -poly(propylene oxide) -poly(ethylene oxide) (PEO-PPO-PEO) boka rine mamorekuru madiki ma surfactants anogona "tuned" nekuvapo kwezvinwiwa zvinodhaka, zvine Kudyidzana kwakasimba kunotungamirira kukuchinja kukuru mu (mixed) micelle morphology, nepo kushamwaridzana kusina simba kunotungamirira kumarudzi ane micelle aripo. Mamiriro uye simba rekubatana pakati pePluronic P123 (EO20PO70EO20) uye madiki mamorekuru surfactants (anionic sodium dodecylsulfate, S42SO CDS), (cationic dodecyltrimethylammonium bromide, C12TAB) uye (non-ionic polyoxyethylene (23) lauryl ether, Brij 35, C12EO23OH) inotarisirwa kuenderana nekugovaniswa kwezvinwiwa zvipfupi, zvepakati uye zvenguva refu (ethanol, hexanol uye decanol zvakateerana) kuferefetwa uchishandisa tensiometry, pulsed-gradient spin-echo nuclear magnetic resonance (PGSE-NMR) uye diki-angle neutron scattering (SANS). Iyo SANS data yeaqueous P123 solutions ine madoro akawedzerwa yakanyatsotsanangurwa nechaji spherical core/shell model. ye micelle morphology.Kuwedzerwa kwema surfactants kwakatungamira kudiki, oblate elliptical yakasanganiswa micelles mukushaikwa kwedoro.Kuwedzerwa kwe ethanol kune aya masisitimu kwakakonzera kudzikira kwehukuru hwe micelle, nepo micelles yakakura yakaonekwa pakuwedzera kweiyo refu cheni doro.Zvidzidzo zveNMR zvakapa fungidziro inopindirana yechimiro chemicelle, uye kupatsanurwa kwezvikamu zvakasiyana mumicelle.
4-Nitrophenyl-N-acetyl-β- D-glucosaminide inobatsira substrate yekukurumidza colorimetric assay yeN-acetyl-b-glucosaminidase basa mumuguta wevanhu.Chromogenic β-Glucosaminidase substrate inobereka yero mhinduro pane cleavage, inoshandiswa kunyanya mumbiriso uye mold.
