AB  - Wound dressings designed with simultaneously adequate antibacterial, sorption, and antioxidant properties enable proper wound healing. Since the antibacterial properties have already been proven in our previous studies, the sorption and antioxidant properties of raw and differently pretreated (TEMPO-oxidized and TEMPO-oxidized cellulose nanofibrils (TOCN) coated) viscose fabrics (CVs), functionalized with chitosan (CH) and chitosan-based nanoparticles with (NCH+Zn) and without incorporated zinc (NCH), were investigated. The sorption properties were evaluated by absorbency rate and capacity, contact angle, zeta potential, and moisture sorption, whereas the antioxidant properties were determined by the ABTS method. The morphological properties of CVs were investigated by SEM. By using pretreatments, the sorption and antioxidant properties of CVs were improved, while subsequent functionalization with CH, NCH and NCH+Zn decreased both properties. However, TOCN-coated CV functionalized with CH and TEMPO-oxidized CV functionalized with NCH still have sorption and antioxidant properties better than raw CV. The obtained results allow the design of antibacterial wound dressings with predefined sorption and antioxidant properties.

AB  - This study aimed to obtain functional viscose textiles based on chitosan coatings with improved antibacterial properties and washing durability. For that reason, before functionalization with chitosan/zinc nanoparticles (NCH+Zn), the viscose fabric was modified by nonthermal gas plasma of dielectric barrier discharge (DBD) to introduce into its structure functional groups suitable for attachment of NCH+Zn. NCH+Zn were characterized by measurements of hydrodynamic diameter and zeta potential and AFM. DBD-plasma-modified and NCH+Zn-functionalized fabrics were characterized by zeta potential measurements, ATR-FTIR spectroscopy, the calcium acetate method (determination of content of carboxyl and aldehyde groups), SEM, breaking-strength measurements, elemental analysis, and ICP-OES. Their antibacterial activity was determined under dynamic contact conditions. In addition to SEM, the NCH+Zn distributions on viscose fabrics were also indirectly characterized by measuring their absorbent capacities before and after functionalization with NCH+Zn. Washing durability was monitored through changes in the zeta potential, chitosan and zinc content, and antibacterial activity after 1, 3, and 5 washing cycles. The obtained results showed that DBD plasma modification contributed to the simultaneous improvement of NCH+Zn sorption and antibacterial properties of the viscose fabric functionalized with NCH+Zn, and its washing durability, making it suitable for the production of high-value-added medical textiles.

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.
