Mechanical properties of alginate reduce in the presence of K+ ions.

Mechanical properties of alginate reduce in the presence of K+ ions. Correct Answer TRUE

In a clinical trial, patients suffering from a lesion in the femoral condyle were successfully treated with the autologous chondrocytes cultured in the alginate–agarose scaffolds. However, alginate gels are relatively unstable in physiological media because of a decrease in mechanical properties of the gels due to the replacement of Ca2+ ions with Na+ or K+ ions in the polymer chains.
