AB  - Nanostructured and bio-active polysaccharide-based thin films were manufactured by means of subsequent spin-coated deposition of a regenerated cellulose (RC) layer and a 2,2,6,6-Tetramethylpiperidine-1-oxyl radical (TEMPO) oxidised cellulose nanofibril (TOCN) layer. The bio-activity of the bilayer was achieved by addition of chitosan (CS). The chitosan was either mixed with the TOCN (TOCN+CS) and deposited on the RC layer by spin-coating, or deposited on the RC and TOCN bilayer by pumping its aqueous solution with various pH over the surface of the bilayer. The water content of the thin films and the CS interactions with the bilayer during deposition were studied in situ by means of a quartz crystal microbalance with dissipation (QCM-D). The pH dependent charging behaviour of the TOCN, TOCN+CS and CS dispersions was evaluated by pH-potentiometric titrations. The surface morphology of the thin films was characterised by atomic force microscopy (AFM). The bio-activity of the thin films was evaluated by studying their protein-repellent properties in situ with a continuous flow of bovine serum albumin (BSA) by means of QCM-D and by evaluating their

AB  - In this work, regenerated cellulose (RC) films was coated with
TEMPO oxidized cellulose nanofibrils (TOCN) and chitosan (CS) by means of
subsequent spin-coated deposition. The bioactivity of coatings was
achieved by addition of chitosan. The chitosan was either mixed
with the TOCN (TOCN+CS) and deposited on the RC film by spin-coating or
deposited on the RC/TOCN bilayer film by pumping its aqueous solution at
pH 5.5 over the surface of the film. The pH dependant charging behaviour
of the TOCN, TOCN+CS, and CS were evaluated by pH-potentiometric
titrations. The protein-repellent properties of investigated coatings were
evaluated in situ using a continuous flow of bovine serum albumin (BSA) by
means of
quartz crystal microbalance with dissipation (QCM-D). Antioxidative
activity of TOCN, CS and their amphoteric mixture was determined using the
2,2′-azino-bis(3-ethyl benzothiazoline-6-sulfonic acid) radical scavenging
assay. Coating with improved protein repellent properties was obtained
using TOCN+CS amphoteric mixture, but on the other hand TOCN+CS amphoteric
mixture showed weaker antioxidative properties in comparison to TOCN and
CS.
