Calcium alginate is a water-insoluble, gelatinous, cream-coloured substance that can be created through the addition of aqueous calcium chloride to aqueous sodium alginate. Calcium alginate is also used for entrapment of enzymes and forming artificial seeds in plant tissue culture. "Alginate" is usually the salts of alginic acid, but it can ...
Alginate dressings are produced from the calcium and sodium salts of alginic acid, a polysaccharide comprising mannuronic and guluronic acid units. Alginate is initially extracted from the cell wall of brown seaweeds. Alginate dressings can be in the form of freeze-dried, porous (foam) sheets or flexible fibres.
[4] [9] The carboxyl or hydroxyl groups on the alginate reagent form complexes during the synthesis of the AgNPs that stabilize the reaction. [4] Nanoparticle size and shape can be specified by changing the ratio of alginate to silver nitrate used and/or the pH. [4] A coating such as PVP may be added to the nanoparticles by heating and ...
Sodium alginate (NaC 6 H 7 O 6) is the sodium salt of alginic acid. Sodium alginate is a gum. Potassium alginate (KC 6 H 7 O 6) is the potassium salt of alginic acid. Calcium alginate (CaC 12 H 14 O 12) is the calcium salt of alginic acid. It is made by replacing the sodium ion in sodium alginate with a calcium ion (ion exchange).
Silver nitrate is also used in certain laboratory procedures to stain cells. As it turns them permanently a dark-purple/black color, in doing so increasing individual cells' visibility under a microscope and allowing for differentiation between cells, or identification of irregularities. Silver is also used in bone prostheses and cardiac ...
