Topochemical Design of Cellulose-Based Carriers for Immobilization of Endoxylanase
Xylooligosaccharides (XOSs) gained much attention for their use in food and animal feed, attributed to their prebiotic function. These short-chained carbohydrates can be enzymatically produced from xylan, one of the most prevalent...
Topochemical Engineering of Cellulose—Carboxymethyl Cellulose Beads: A Low-Field NMR Relaxometry Study
The demand for more ecological, highly engineered hydrogel beads is driven by a multitude of applications such as enzyme immobilization, tissue engineering and superabsorbent materials. Despite great interest in hydrogel fabrication and...
Topochemical engineering of composite hybrid fibers using layered double hydroxides and abietic acid
Topochemical engineering of hybrid materials is an efficient way of synthesizing hydrophobic and highly tensile fiber composites by utilizing the intermolecular hydrogen bonds in natural materials. These materials include wood pulp fibers,...
A Novel Catalyst: Biohybrid cellulose beads
Cellulose-based materials are very attractive for emerging bioeconomy as they are renewable, inexpensive, and environmentally friendly. Cellulose beads are spherical and porous and can be highly engineered to be used as catalyst...
Solid‐state properties and controlled release of ranitidine hydrochloride
Oxidised cellulose beads (anionic groups 0.1–1.85 mmol g−1) were loaded with ranitidine HCl. Polymorphic form and crystallinity of the drug was assessed by calorimetric and spectrometric techniques. Release profiles were obtained at physiological conditions...
Fluorescent multifunctional fibres
The paper describes the synthesis of multifunctional cellulose derivatives (MCDs) containing a fluorescent and a cationic moiety and their application in the functionalization of pulp fibers. The cellulose derivatives, namely N-(3-propanoic acid)-...
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...
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...
