“…cellulose, is continuously scoring points in all domains of research particularly on the development of multifunctional materials [1][2][3]. In fact, the versatility of cellulose is even fostered when its nanoscale forms are considered, namely cellulose nanofibrils (CNFs), cellulose nanocrystals (CNCs) and bacterial cellulose (BC), whose interest for the design of innovative and all-purpose nanomaterials has skyrocketed during the last couple of years, including in the nanocomposites domain [4][5][6][7][8][9].…”

Recent studies have demonstrated the potential of bacterial cellulose (BC) as a substrate for the design of bio-based ion exchange membranes with an excellent combination of conductive and mechanical properties for application in devices entailing functional ion conducting elements. In this context, the present study aims at fabricating polyelectrolyte nanocomposite membranes based on poly(bis[2-(methacryloyloxy)ethyl] phosphate) [P(bisMEP)] and BC via the in-situ free radical polymerization of bis[2-(methacryloyloxy)ethyl] phosphate (bisMEP) inside the BC three-dimensional network under eco-friendly reaction conditions. The resulting polyelectrolyte nanocomposites exhibit thermal stability up to 200 • C, good mechanical performance (Young's modulus > 2 GPa), water-uptake ability (79-155%) and ion exchange capacity ([H + ] = 1.1-3.0 mmol g −1 ). Furthermore, a maximum protonic conductivity of ca. 0.03 S cm −1 was observed for the membrane with P(bisMEP)/BC of 1:1 in weight, at 80 • C and 98% relative humidity. The use of a bifunctional monomer that obviates the need of using a cross-linker to retain the polyelectrolyte inside the BC network is the main contribution of this study, thus opening alternative routes for the development of bio-based polyelectrolyte membranes for application in e.g., fuel cells and other devices based on proton separators.

“…Three main classes of NC exist: cellulose nanocrystals (CNCs), nanofibrillated cellulose (NFC), and bacterial NC (BNC). NC can be extracted from various biosources and it is easily chemically or physically modified (Kargarzadeh et al, ). Like other nanomaterials, NC shows a high surface to volume ratio and improved solubility compared to natural cellulose.…”

Carbohydrates are abundant biomolecules, with a strong tendency to form supramolecular networks. A host of carbohydrate-based nanomaterials have been exploited for biomedical applications. These structures are based on simple monoor disaccharides, as well as on complex, polymeric systems. Chemical modifications serve to tune the shapes and properties of these materials. In particular, carbohydrate-based nanoparticles and nanogels were used for drug delivery, imaging, and tissue engineering applications. Due to the reversible nature of the assembly, often based on a combination of hydrogen bonding and hydrophobic interactions, carbohydrate-based materials are valuable substrates for the creations of responsive systems. Herein, we review the current research on carbohydratebased nanomaterials, with a particular focus on carbohydrate assembly. We will discuss how these systems are formed and how their properties are tuned. Particular emphasis will be placed on the use of carbohydrates for biomedical applications.

“…Nanocellulose as a new class of nano‐structured form of cellulose, can be classified into three main subcategories: nanocrystalline cellulose (NCC), nanofibrillated cellulose (NFC) and bacterial cellulose (BC) produced by bacterial species. The preparation methods of cellulose from different sources have a large influence on final features and properties of the produced nanocellulose . Within the family of nanocellulose derivatives, NCC is particularly appealing due to feature unique properties such as size and morphology.…”

In this study, nanocrystalline cellulose (NCC) prepared from microcrystalline cellulose using high‐intensity ultrasonication as mechanical method without any chemical treatment. The obtained NCC with around 30–50 nm diameters, utilized as support, reducing and stabilizing agent for in‐situ green and eco‐friendly synthesis of silver nanoparticles (Ag NPs). The catalytic activity of composite was examined for degradation of environmental pollutants. The structure of as‐synthesized composite (Ag@NCC) was characterized by ultraviolet–visible spectroscopy (UV–vis), field emission scanning electron microscopy (FE‐SEM); Transmission electron microscopy (TEM); Energy dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FT‐IR), X‐ray diffraction (XRD) and thermogravimetric analysis (TGA). The results of the catalytic reaction experiments showed that spherically shaped silver nanoparticles of around 20 nm distributed on the surface of nanocellulose demonstrated high catalytic efficiency towards the removal of methyl orange (MO) and 4‐nitrophenol (4‐NP).
