Abstract:This work is focused on surface characterization and fibrinogen adsorption studies of polycaprolactone/chondroitin sulfate (tetrabutylammonium hydroxide) blends. Mixed polymer solutions were spin-coated to form two-phase thin films, which exhibit various patterns depending on the mass ratio of the spin-coating solution. Stability in the aqueous media, however, presents an uncertainty, due to the solubility of chondroitin sulfate (tetrabutylammonium hydroxide) in water. In spite of this, it is observed that the introduction of chondroitin sulfate (tetrabutylammonium hydroxide) in the film increases the repulsion of fibrinogen. Two methods frequently used for polymer characterization, mass determination using Quartz Crystal Microbalance with Dissipation monitoring and the zeta potential measurement, were found to be comparable techniques when studying protein adsorption and complementary techniques when analysing the stability of thin films.

Title:Protein odbojni površinski sloji narejeni iz polikaprolakton-polisaharid zmesi
Abstract:Magistrsko delo raziskuje površinske lastnosti polikaprolakton-polisaharid zmesi in njihov vpliv na adsorpcijo fibrinogena. Dvofazni tanki filmi so bili uspešno pripravljeni iz mešane polimerne raztopine z uporabo »spin coating« metode in tvorijo različne vzorce, odvisno od masnega razmerja polimerov. Stabilnost filmov v vodnem mediju predstavlja negotovost zaradi topnosti hondroitin sulfata (tetrabutilamonijevega hidroksida) v vodi. Kljub temu se v povprečju ob vnosu hondroitin sulfata (tetrabutilamonijevega hidroksida) v film kaže povečan odboj fibrinogena. Dve metodi, ki se pogosto uporabljata za karakterizacijo polimerov, merjenje mase s kremenovo mikrotehtnico z disipacijo in merjenje zeta potenciala, sta se izkazali kot primerljivi tehniki za preučevanje adsorpcije beljakovin in komplementarni tehniki za analizo stabilnosti tankih filmov.
Keywords:polikaprolakton, hondroitin sulfat, zeta potencial, QCM-D, fibrinogen, adsorpcija
