Abstract Flocculation is used for the removal or separation of colloids, e.g. in water treatment and mineral processing. Alginates are linear, anionic biopolymers composed mannuronic (M) guluronic (G) acids. The relative amount distribution M G impact ion-binding gel-forming properties polymer, but still no one has yet addressed alginate composition on flocculation nanoparticles particles. Our ...

Objective(s): Alginates play a key role in mucoid Pseudomonas aeruginosa colonization, biofilm formation, and driving out of cationic antibiotics. P. aeruginosa alginate lyase (AlgL) is a periplasmic enzyme that is necessary for alginate synthesis and secretion. It also has a role in depolymerization of alginates. Using AlgLs in cystic fibrosis patients along with anti...

objective: the aim of this study was to evaluate the dimensional stability of casts made from an alginate impression material poured immediately and stored after specific periods. materials and methods: the common alginate used in iran (super; iralgin, golchai co., tehran, iran) was tested. a master model was mounted on a special device and used to obtain the impressions. these impressions were...

Microfabrication techniques and microfluidics are increasingly being used in single-cell research. Surface patterning of cell adhesive and non-fouling patches, for instance, can confine cells to arbitrary shapes on two-dimensional surfaces, whereas laminar flow can be used to deliver pharmacological agents to well-defined parts of cells. Together with the powerful tools available through molecu...

Bacterial anchoring to limestone rocks is thought occur by selective adsorption of biomolecules found in the extracellular matrix, such as polysaccharides. Here we study adsorbed structure a model matrix polysaccharide, sodium alginate, at calcite/water interface using neutron reflection (NR). Sodium alginate was form highly hydrated layers extending up 350 Å into solution concentrations 2.5 pp...

Recently, efforts have been focused on microparticles prepared with natural polymers such as alginates and chitosans. Sodium alginate in particular has been commercially applied and investigated due to its low cost and minimal processing requirements (Murata et al., 1993; Gombotz & Wee, 1998; Sezer & Akbuga, 1999a and b). The use of sodium alginate for microencapsulation has been extensively st...
