Chemical, physical and biological properies of alginates and their biomedical implications. Cytotoxic effect of saffron stigma aqueous extract on human transitional cell carcinoma and mouse fibroblast. A schematic representation of gelation for progressive and cooperative fixation of calcium is given in Figure 2.

Conclusion From this short review, it seems clear that alginates are new industrial polysaccharides which may be used in many other applications than only food industry. Polysaccharide- based hydrogels in tissue engineering, in Polysacharides.

New generation of medical textiles are an important growing field, showing great expansion, in wound management products Fibers have an efficient antimicrobial activity maintained after 30 laundry cycles non-leaching antimicrobial agent Polysaccharide Functional Properties eds. Haemostasis and tissue repair is an important domain of development of alginate produced as thin filament in the calcium form.

The role of guluronic acid blocks GG blocks is particularly important for gel mechanical properties in presence of calcium counterions. Food Hydrocolloids 23 Mycobased synthesis of silver nanoparticles and their incorporation into sodium alginate films for vegetable and fruit preservation. Alginate calcium fibers is an inherent flame-retardant fiber.

Citotoxicidad de Alginatos Dentales

Pure and Applied Chem istry 42 Alginates applications Alginates in Foods Up to now, the main applications of alginates were based mainly on their gel-forming ability and used as food additives in jams, jellies Amongst these metals, one can cite the lead, which is present in the alginate powders to improve their elastic properties following gelification despite sometimes being found as an impurity Braga et al.

The other alginates had intermediate results. Under their monovalent salt form especially sodium formalginates are perfectly water soluble and increase of solvent viscosity upon dissolution causing an interesting thickening character in relation with the semi-rigid conformation of this copolymer which found valuable applications.

Nevertheless, biomedical and pharmaceutical complsicion of purified alginates seem certainely the most promising development of alginates at present time. The gel-forming process for alginate fibers and the gelling behavior of various types of alginate fibers were described. Alginate applications, alginate composition, alginate fibers, alginate properties, Ca-gelation.

They are now widely used in the management of highly exuding wounds such as leg algimato, pressure sores, and surgical wounds Relationship between the molecular structure of alginates and their gelation in acidic conditions.

After this period, the cells were fixed using ? Introduction Marine algae constitute a large source of natural polysaccharides having original physical properties. Cytotoxicity of dental alginates.

New products are now proposed for microwave heating denttal using active packaging with susceptors. Alginates fibers were reinforced by introduction of hydrolysed chitosans which diffuse into the alginate fiber allowing to introduce antibacterial properties Carbohydrate Research 27 The relative extension of alginates having different chemical composition.

Alginate as immobilization material: Alginates in paper industry Alginate partially complexed with calcium such as forming a loose gel mixed with starch was proposed to get high water retention in paper coating.

Assessing the Cytotoxity of the Materials.

Imparting durable antimicrobial properties to cotton fabrics using alginate quaternary ammonium complex nanoparticles. The total sample consisted of 14 dental alginates from different manufacturers and divided into 14 groups as follows:
