Structural Characterization of Sodium Alginate and Calcium Alginate
Biomacromolecules, 2016Alginate readily aggregates and forms a physical gel in the presence of cations. The association of the chains, and ultimately gel structure and mechanics, depends not only on ion type, but also on the sequence and composition of the alginate chain that ultimately determines its stiffness.

Effect of alginate composition and purity on alginate microspheres
Journal of Microencapsulation, 2004Alginate is commonly used to microencapsulate islets in experiments with islet allografts and xenografts for the treatment of Type I diabetes. The purpose of the present study is to determine the effects of alginate composition and purity on the morphology and size of microspheres.Microcapsules produced with the impure alginate types, medium-viscosity ...

Biomacromolecules, 2011
Distribution and proportion of β-D-mannuronic and α-L-guluronic acid in alginates are important for understanding the chemical-physical properties of the polymer. The present state of art methods, which is based on NMR, provides a statistical description of alginates.

Journal of Wound Care, 2021
Background: All fibrous wound dressings are considered to have the same action and value to the support of wound healing. Although clear distinction has been accepted between cotton gauze and calcium alginates, there is still no formally recognised distinction between calcium alginates and the more rapidly gelling fibre dressings.

The conversion of calcium alginate fibers into alginic acid fibers and sodium alginate fibers
Journal of Applied Polymer Science, 2006AbstractAlginate is a natural polymer extracted from brown seaweeds. Over the last two decades, alginate fibers have become well established in the wound management industry where their ion exchange and gel forming abilities are particularly useful in the treatment for exuding wounds.

Effect of the alginate composition on the biocompatibility of alginate-polylysine microcapsules
Biomaterials, 1997Alginate-polylysine (PLL) capsules are commonly applied for immunoprotection of endocrine tissues. Alginate is composed of mannuronic acid (M) and guluronic acid (G). Different types of alginate have different ratios of G to M, but little is known of the influence of these differences on biocompatibility.

Characteristics of sausage as prepared with alginate and alginate casings
Food / Nahrung, 1982AbstractFresh buffalo sausage was prepared with 3 % sodium alginate, 0.5 % sodium pyrophosphate or 3 % alginate + 0.5 % sodium pyrophosphate and stuffed in natural mutton casing or alginate casing. All samples were stored at +4 °C and analysed.Addition of 3 % alginate was more effective in protection of sausages from drying, increased markedly the ...

Biocompatibility Evaluation of Different Alginates and Alginate-Based Microcapsules
Biomacromolecules, 2005Biocompatibility of biomaterials and biomaterial-based medical devices is a critical issue for the long-term function on multiple therapeutic systems. In the past few years, there has been an increasing interest in producing more biocompatible biomaterials and in developing novel assays to analyze the quality of the products.

Alginate for Duplication Procedure
The Journal of the American Dental Association, 1972The accuracy of a series of casts produced by alginate duplication of an electroplated master cast was compared by clinical observations with that produced by hydrocolloid duplication. Alginate may be used as a duplicating material if temperature, spatulation, water-powder ratio, and pouring intervals are controlled properly.
