Covalent core–shell structured protein clusters of hemoglobin (Hb) and human serum albumin (HSA) (HbX-HSAm) (m = 2, 3) with novel physiological properties were generated by linkage of Hb surface lysins to HSA cysteine-34 via an α-succinimidyl-ε-maleimide cross-linker (X: 1 or 2). The ...

The effect of the addition of NaCl or CaCl2 on the structure of protein particles and gels was investigated in detail for aqueous solutions of the globular milk protein β-lactoglobulin at 40g/L and pH 7.0. When heated in the presence of NaCl or at very low CaCl2 concentrations, the proteins ...

Pulp of high cellulose content, also known as dissolving pulp, is needed for many purposes, including the production of cellulosic fibers and films. Paper-grade pulp, which is rich in hemicellulose, could be a cheap source but must be refined. Hitherto, hemicellulose extraction procedures ...

Cinnamaldehyde treatment of gliadin films provided a means of decreasing their solubility, increasing their molecular weight profile, and reducing their overall migration into food simulants as a consequence of the high degree of polymerization achieved. Despite losses incurred in the film ...

Controlling the structure and organization of electrospun fibers is desirable for fabricating scaffolds and materials with defined microstructures. However, the effects of microtopography on the deposition and, in turn, the organization of the electrospun fibers are not well understood. In ...

Normal (e.g., adhesion) and lateral (friction) forces were measured between physisorbed and chemically grafted layers of hyaluronic acid (HA), an anionic polyelectrolyte in the presence of lubricin (Lub), a mucinous glycoprotein, on mica surfaces using a surface forces apparatus (SFA). This ...

Surface grafting of crystalline and ultrafine cellulose nanofibrils with poly(ethylene glycol) (PEG) chains via ionic bonds was achieved by a simple ion-exchange treatment. The PEG-grafted cellulose nanofibrils exhibited nanodispersibility in organic solvents such as chloroform, toluene, and ...

A strategy to light-trigger ionic cross-linking of alginates by incorporating a photosensitive Ca2+ cage (nitr-T) is presented. Upon irradiation, free Ca2+ was released, and this caused gelation of the alginate solution. Addition of Ca2+ “on-demand” allowed us to obtain homogeneous alginate ...
