Multifunctional hydrogel beads for tissue engineering

Multifunctional hydrogel beads for tissue engineering

Cytocompatible polysaccharide-based functional scaffolds are potential extracellular matrix candidates for soft and hard tissue engineering. This paper describes a facile approach to design cytocompatible, non-toxic, and multifunctional chitosan-cellulose based hydrogel beads utilising...

Cellulose fibre-reinforced biofoam

Traditionally, polymers and macromolecular components used in the foam industry are mostly derived from petroleum. The current transition to a bio-economy creates demand for the use of more renewable feedstocks. Soybean oil...

A new class of superhydrophobic hybrid materials

Technical composite materials derived from renewable sources are always of high importance due to cost-effectiveness and environmental concern. Cellulose, a renewable biopolymer stays constantly at the high realm in terms of valorization...

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)-...

Functional Cellulose Beads

The preparation of cellulose-based materials is an area of increasing interest for scientists working in chemistry, chemical engineering, biochemistry, and many other related areas involving the chemical design of biobased materials. Polysaccharides...

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...
