We successfully fabricated (chitosan/alginate) (CHI/ALG) multilayer thin film by layer-by-layer (LBL) method. Film durability was enhanced by forming cross-linking using heat treatment, glutaraldehyde, and calcium chloride. Indeed, the adsorption of fibrinogen onto CHI/ALG multilayer thin film was determined by QCM system and it was found that physical stability and protein resistance of CHI/AL...

A novel hydrogel, based on an alginate/hyaluronate mixture and Ce(III) ions, with effective bioactive and antimicrobial ability was developed to be used as vehicle of a synthetic bone substitute producing an injectable substitute (IBS). Firstly, three different IBSs were prepared using three developed alginate-based hydrogels, the hydrogel Alg composed by alginate, the hydrogel Alg/Ch composed ...

Chitosan and Carbopol have been used to form a complex through an electrostatic interaction between the protonated amine (NH3+) group of chitosan and the carboxylate (COO-) group of Carbopol. In situ polyelectrolyte complexes formations based on the physical mixture of chitosan and sodium alginate were found and could be used as an oral controlled release matrix. The aim of this work is the ass...

Objective: The present study aimed to develop and characterize Chitosan coated Alginate Nanocapsules loaded with M-Insulin Concanavalin A Complex for glucose-responsive delivery. Methods: Preformulation studies were performed on the Insulin human recombinant prepared by ionic gelation method chitosan using electrostatic attraction. formulation variables optimized Box-Behnken design (BBD) help o...

Owing to environmental pollution and increasingly strict regulations, heavy metals have attracted the attention of many researchers in various disciplines. Alginate chitosan derivatives gained popularity as biosorbents for water treatment. An increase number publications on modified biosorption toxic compounds reveals widespread interest examining requirements positive contribution each modific...

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...

Herein, it is aimed to highlight the importance of process parameter choice during directional solidification polymer solutions, as they have a significant influence on pore structure and orientation. Biopolymer solutions (alginate chitosan) are directionally frozen, while systematically varying parameters such external temperature gradient, overall system, temperatures cooling surfaces. In add...

Wound healing is a complicated yet necessary event that takes place in both animals and human beings for the body to repair itself due injury. involves various stages ensure restoration of injured tissue at end process. dressing material acts as protective extracellular barrier against potential damage injury microbial invasion. Naturally, polysaccharides (chitosan alginate) have inherent prope...

HIGHLIGHTS Alginate/Chitosan is the second most abundant polysaccharide on earth. PRF (platelet-rich fibrin) potential to play adjunct roles in regenerative medicine. 3D printing grafts can increase wound healing capacity. Prospective of combining with different biomaterials promotes tissue regeneration.
