Development of nanofiber-reinforced hydrogel scaffolds for nucleus pulposus reg...
Thorvaldsson, A.; Correia, Joana Silva; Oliveira, Joaquim M.; Reis, R. L.; Gatenholm, P.; Walkenström, P.In this work a new method is presented to efficiently produce hydrogel scaffolds reinforced with nanofibers to show enhanced mechanical properties and improved structural integrity. The method is based on a combination of air brush spraying of a hydrogel and electrospinning of nanofibers. With air brush spraying the controllability is enhanced and the potential for scale-up increased. The developed method was u...
Lipases efficiently stearate and cutinases acetylate the surface of arabinoxyla...
Stepan, A. M.; Anasontzis, G. E.; Matamá, Maria Teresa; Paulo, Artur Cavaco; Olsson, L.; Gatenholm, P.This is the first report on successful enzyme catalyzed surface esterification of hemicellulose films. Enzyme catalyzed surface acetylation with vinyl acetate and stearation with vinyl stearate were studied on rye arabinoxylan (AX) films. Different surface analytical techniques (FT-IR, TOF-SIMS, ESCA, CA) show that lipases from Mucor javanicus, Rhizopus oryzae and Candida rugosa successfully surface stearate AX...
