Abstract
Polietilenimin (PEI) sintetski je kationski polimer čija funkcionalnost i reaktivnost potječu od činjenice da se radi o polimeru koji sadrži primarne, sekundarne i tercijarne skupine amina. Zbog ovakve građe, PEI ima veliku gustoću naboja što omogućuje postizanje jednakog učinka imobilizacije enzima uz manju količinu polimera, a da pri tome ne dođe do aglomeracije enzima. Ovaj je polimer fleksibilan i jednostavan za uporabu, pristupačne je cijene te omogućuje dodatnu uštedu zbog mogućnosti ponovne uporabe enzima nakon imobilizacije. PEI koristi se u brojne svrhe, primjerice kao ljepilo za imobilizaciju enzima i ko-imobilizaciju višeslojnih enzima, kao sredstvo za imobilizaciju enkapsuliranjem te za pripremanje imobilizacijskih podloga. Svojstva polietilenimina, načini njegova dobivanja i primjeri uporabe u industriji bit će detaljnije prikazani u nastavku ovoga završnog rada.
Abstract (english)
Polyethylenimine (PEI) is a synthetic cationic polymer whose functionality and reactivity arise from the fact that it contains primary, secondary and tertiary amino groups. Due to such structure, PEI has a high charge density which enables an effective enzyme immobilization with a smaller amount of polymer, while disabling enzyme agglomeration. This polymer is flexible, easy to use and it is affordable which allows additional savings due to the possibility of immobilized enzyme reuse. PEI is used for many purposes, e.g. as an immobilization glue, for co-immobilization of enzyme multilayers, for enzyme encapsulation and for preparation of immobilization supports. PEI properties, methods of its production, as well as some of the examples of its use in industry will be presented in this undergraduate thesis.
