Phenology and alginates of two Sargassum species from the Caribbean coast of Colombia
(Ciencias Marinas, 2012)
The genus Sargassum (Phaeophyceae) forms large beds on rocky shores of the Colombian Caribbean, showing large seasonal fluctuations in biomass that are related to upwelling events in the area. This study describes the ...
Thermal, microstructural, and spectroscopic analysis of Ca2+ alginate/clay nanocomposite hydrogel beads
(2018-09-01)
Polymeric hydrogels are important biomaterials with potential for various applications including the controlled release of drugs. Clay and zeolite nanostructures can enhance the absorption and release properties of hydrogels. ...
Review of the characterization of sodium alginate by intrinsic viscosity measurements: Comparative analysis between conventional and single point methods
(Open Science Publishing, 2014-05)
In the pharmaceutical and food industry, alginate is used in aqueous solutions and excipients as thickener, gelling agent, coagulant and encapsulant. This biopolymer is very important, with many key industrial applications, ...
Evaluation of diclofenac sodium incorporation in alginate membranes as potential drug release system
(Elsevier, 2020-08)
In this study, we proposed the use of the biopolymer alginate to produce membranes with diclofenac sodium incorporated as model-drug aiming at wound dressing application with drug delivery. The membranes were prepared by ...
BLOCK STRUCTURE IN ALGINIC ACID FROM LESSONIA VADOSA (LAMINARIALES, PHAEOPHYTA)
(Sociedad Chilena de Química, 2007)
Determination of calcium by atomic absorption spectrophotometry applied to the preparation of alginate:chitosan complexes
(2004-12-01)
Polysaccharicles, as alginate and chitosan, have been used to obtain modified release dosage forms. Alginate, due to its property of building gels during the complex formation with calcium ions, allows the building of ...
Quantitative analysis of potentially toxic metals in alginates for dental use
(2005-12-01)
Alginate is one the materials most employed in practice to make dental impressions. Substances like zinc, cadmium and lead silicate, which are included in several alginate brands with the aim of improving their physical, ...
