Cellulose

Cellulose nanomaterials are produced employing a multitude of methodologies including electrospinning, bacterial generation, acid digestion, and a variety of mechanical defibrillation techniques; the morphology of the nanomaterial produced is specific to the production process. Feedstocks range from…

Currently, design and development of formulations for the oral cavity and local application is a rather challenging process since the components should be non-irritant and provide relief. Hydrogels-based drug delivery systems have been proposed as suitable candidates for oral mucosal (eg, buccal,…

Amorphous solid dispersions (ASDs) are regarded as one of the most promising techniques for poorly-soluble active pharmaceutical ingredients (API). However, the thermodynamic instability of ASDs at supersaturated state makes them easy to recrystallize in aqueous media. In this study, ritonavir…

Piribedil (PBD) is an anti-Parkinson’s drug that gained interest recently due to its unique pharmacological profile. But its clinical use is severely limited by drug delivery issues like high dosing frequency (up to 5 tablets/day), low oral bioavailability (<10%), severe GI side-effects, etc. In…

We designed three types of hollow-shaped porous silica materials via a three-step biotemplate-directed method: porous hollow silica nanorods, hollow dendritic fibrous nanostructured silica (DFNS), and ultraporous sponge-like DFNS. The first step was making a biotemplate, for which we used cellulose…

Hydrogels are an attractive system for a myriad of applications. While most hydrogels are usually formed from synthetic materials, lignocellulosic biomass appears as a sustainable alternative for hydrogel development. The valorization of biomass, especially the non-woody biomass to meet the growing…
