Biocatalytic fibre surfaces

Biocatalytic fibre surfaces

Biocatalytic pulp fibers were prepared using surface functionalization of bleached kraft pulp with amino groups (F) and further immobilization of a cross-linked glucose oxidase (G*) from Aspergillus niger. The cross-linked enzymes (G*)...

Cellulose biotemplate for inorganic porous networks

Synthesis of porous network structures of layered double hydroxides (LDH) has been studied using microcrystalline cellulose (MCC) as a hard template. LDH was synthesized using cellulose as biotemplate and post treated by...

Antimicrobial hybrid cellulose-lignin beads

In the present study, cellulose-lignin beads were prepared using pretreated dissolving grade-pulp and extracted from birch wood hydrotropic lignin as starting materials. The preparation involved dissolution of both polymers in environmentally friendly...

Tailored cellulose beads for drug release

In the frame of this work, we have investigated drug entrapping and release abilities of new type of porous cellulose beads (CBs) as a spherical matrix system for drug delivery. For that...

Anionic cellulose beads for drug encapsulation and release

Cellulose beads were prepared from water-based solvent and oxidised by modified Anelli’s reaction at 20– 80∘C80∘C for 2–48 h (Fig. 1). The maximum amount of anionic groups (AGs) was 1.85mmolg−11.85mmolg−1 . The...

Polysaccharide-based polyelectrolyte complexes

Molecular assemblies, namely, polyelectrolyte complexes (PECs) composed of negatively charged xylan-based derivatives and a novel positively charged cellulose derivative (CN+), were used for interfacial modification of wood fibers by charge directed self-assembly....

Nanofibrous graft for bone tissue engineering

Nanofibers coated onto the bone implant as a dual-layered material has supported the regeneration of bone cells suitable for bone tissue engineering. Herein, we report the electrospinning of Poly(3-Hydroxybutyric acid)-Poly(N-vinylpyrrolidone) NanoFibrous Matrix...

New zwitterionic cellulose beads

The design and synthesis of polysaccharide-based materials utilizing a systematic approach is essential to develop sustainable and biodegradable value added products. In this work, new zwitterionic cellulose beads of desired size range...

Photocrosslinking of cellulose fibres

Photoresponsive pulp fibers are prepared by self‐assembly of photoactive cationic cellulose derivatives with pulp fibers in aqueous environment. Photoactive groups of the derivatives undergo 2π + 2π cycloaddition reaction under UV‐light irradiation. Fast photocrosslinking...

Surfaces of chitosan treated viscose fibres

Time-of-flight secondary ion mass spectrometry (ToF-SIMS) was employed to analyse cellulose viscose fibres treated with different chitosan-based solutions. The analysis reports several new features in the TOF-SIMS spectra for systems with various...
