Alginate is a commonly used biomedical hydrogel whose in vivo degradation behavior is only beginning to be understood. The use of alginate in the central nervous system is gaining popularity as an electrode coating, cell encapsulation matrix, and for duraplasty. However, it is necessary to understand how the hydrogel will behave in vivo to aid in the development of alginate for use as a neural ...

The use of bone allografts is contraindicated in septic revision surgery due to the high risk of graft reinfection. Antibiotic release from the graft may solve the problem and these combinations can theoretically be used for prevention or even therapy of infection. The present study investigated whether amoxicillin, ciprofloxacin, and vancomycin alone or in combination with chitosan or alginate...

Citrus genus is known as one of the world's major economic agricultural products. In the current research, a method is reported for artificial seed production technology by shoot tips in Citrus sinensis.var. Thamson navel. Alginate is one of the most efficient gelling agents in the production of capsule coating in artificial seeding technique. In the current research, impact of different consti...

Three-dimensional (3D) printing is an emerging technology for the fabrication of scaffolds to repair/replace damaged tissue/organs in tissue engineering. This paper presents our study on 3D printed alginate scaffolds treated with phosphate buffered saline (PBS) and polyethyleneimine (PEI) coating and their impacts on the surface morphology and cellular response of the printed scaffolds. In our ...

Oxidized sodium alginate is a handily modifiable polysaccharide owing to the pendant aldehyde groups which can form dynamic covalent bonds with amines, acylhydrazines, etc., providing oxidized sodium alginate-based hydrogels with stimuli-responsive properties. However, due to the stiffness and, in particular, the hydrophobicity of sodium alginate dialdehyde at low pH, the mechanical performance...

This study investigated the effects of pectin, chitosan, sodium alginate, and carboxymethyl cellulose-based edible coatings, individually and/or in combination with N-acetyl cysteine as an antibrowning agent, on some physical, chemical, antioxidant properties white button mushrooms. The weight loss, color change, browning index, degree cap opening, soluble solid content, total phenolic activity...

High-Efficiency Oil–Water Filter In article number 2100594, Jiawei Hu, Yi Chen, and co-workers prepare a high-efficiency oil–water filter by coating sodium alginate hydrogel layer in the surface of porous sand core. This exhibits excellent separation ability toward mixed liquor emulsion. Moreover, it has chemical stability, easy cleanliness, strong durability. All these characteristics make thi...

Department of Applied Physics, University of Fukui, Bunkyo 3-9-1, Fukui, 910-8507 Japan Abstract Sodium alginate solution, being viscous hydrocolloid, was examined voltammetrically in the context of viscous effects by use of a ferrocenyl compound as a redox probe. Voltammograms were almost independent of concentrations of sodium alginate even in a solid-like state. Diffusion coefficients of the...

The present study was aimed to develop and evaluate Albendazole microcapsules using guar gum, a natural polymer for colon-specific delivery for better treatment of Helminthiasis, Filariasis, and colorectal cancer by avoiding the side effects. Microcapsules were prepared by the use of different concentrations of sodium alginate and guar gum. The polysaccharides guar gum reacted with sodium algin...

Modification of polymers by covalent attachment of thiol bearing pendant groups is reported to impart many beneficial properties to them. Hence in the present study, sodium alginate-cysteine conjugate was synthesized by carbodiimide mediated coupling under varying reaction conditions and the derivatives characterized for thiol content. The thiolated alginate species synthesized had bound thiol ...
