Sažetak


U ovom radu dat je pregled metoda izrade mikrofluidnih uređaja i sistema kao i mogućnosti njihove primene. Mikrofabrikacione metode predstavljaju različite procedure, metode i varijacije. Metodologija izrade mikrofluidinih uređaja direktno utiče na mogućnost njihove primene, kao i primene različitih medijumima. Metode izrade mikrofluidnih uređaja mogu se podeliti na osnovu mehaničkih svojstava materijala. U ovom radu izvršena je podela metoda fabrikacije na osnovu krutosti materijala. Krutost materijala najviše utiče na veličinu i rezoluciju struktura koje se mogu izraditi. Na osnovu krutosti materijala koji se koriste za izradu mikrofluidnih uređaja vrši se klasifikikacija na tvrde, plastične i meke materijale. Tvrdi materijali koji se najčešće primenjuju u procesu fabrikacije su staklo i silikon. Plastični materijali koji se koriste u procesu fabrikacije su Poli(metil metakrilart), Ciklični olefinski kopolimer, itd., dok se primena mekih materijala u procesu fabrikacije bazira na Polimetilsiloksanu. Primena metoda fabrikacije zavisiće i od mogućnost primene u toplim ili hladnim, reaktivnim ili neutralnim sredinama kao i od biokompaktibilnosti samog uređaja. Neke od najrasprostranjenijih metoda izrade mikrofluidnih uređaja predstavljene su fotolitografija i njene varijacije, metode graviranja koje se koriste za staklo i silikon, livenje Polimetilsiloksana, mikroglodanje i 3D štampanje. Kao i papirna mikrofluidika kao primer metode za izradu biokompaktibilinh mikrofluidnih uređaja sa primenom u medicini.
