Fabrication of cellulose cryogel beads via room temperature dissolution in onium hydroxides

Fabrication of cellulose cryogel beads via room temperature dissolution in onium hydroxides

In recent years, there has been a growing interest in green solvents to dissolve and shape cellulose into microspheres. However, development of solvents suitable for room temperature dissolution and shaping of cellulose...

Porous soluble dialdehyde cellulose beads: A new carrier for the formulation of poorly water-soluble drugs

Cellulose beads are porous spherical particles with promising futures for drug delivery applications. In this study, novel dialdehyde cellulose (DAC) beads are developed by periodate oxidation of pristine cellulose for oral delivery of weakly...

Valorization of Aloe barbadensis Miller. (Aloe vera) Processing Waste

Aloe vera plant is known worldwide for its medicinal properties and application in gel-based products such as shampoo, soap, and sunscreen. However, the demand for these gel-based products has led to a surplus...

Structural characterization and protective effects of polysaccharide from Gracilaria lemaneiformis on LPS-induced injury in IEC-6 cells

This study was aimed to characterize Gracilaria lemaneiformis polysaccharides and evaluate their protective effects on Lipopolysaccharide-induced injury in IEC-6 cells. The G. lemaneiformis polysaccharide was degraded by UV/H2O2 treatment and purified to three fractions named GLP-1.0 M, GLP-1.4 M...

Preparation and properties of polyvinyl alcohol/N–succinyl chitosan/lincomycin composite antibacterial hydrogels for wound dressing

Hydrogels are three-dimensional polymeric networks capable of absorbing large amounts of water or biological fluids with the properties resembling natural living tissues. Herein, polyvinyl alcohol (PVA)/N–succinyl chitosan (NSCS)/lincomycin hydrogels for wound dressing...

ACS Applied Materials and Interfaces webinar with Dr Luiz Mattoso (Embrapa) and Dr Pedro Fardim (KU Leuven/EPNOE).

TEMPO-oxidized cellulose beads as potential pH-responsive carriers for site-specific drug delivery in the gastrointestinal tract

The development of controlled drug delivery systems based on bio-renewable materials is an emerging strategy. In this work, a controlled drug delivery system based on mesoporous oxidized cellulose beads (OCBs) was successfully...

In vitro and in vivo evaluation of poly-3-hydroxybutyric acid-sodium alginate as a core-shell nanofibrous matrix with arginine and bacitracin-nanoclay complex for dermal reconstruction of excision wound

The protective layer of the body, the skin is often prone to damage due to several factors like trauma, accidents, stress and hazardous exposure. This requires the skin to regenerate itself which...

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...
