Gelation in Alginate-Based Magnetic Suspensions Favored by Poor Interaction among Sodium Alginate and Embedded Particles

Alginate gels are extensively tested in biomedical applications for tissue regeneration and engineering. In this regard, the modification of alginate solutions with dispersed magnetic particles gives extra options to control rheo-elastic properties both fluidic gel forms alginate. Rheological suspensions based on Na-alginate water solution embedded were studied respect interfacial adhesion polymer surface particles. Particles magnetite (Fe3O4), metallic iron (Fe), nickel (Ni), a deposited carbon layer (Ni@C) taken into consideration. Storage modulus, loss shift angle between stress strain characterized by dynamic mechanical analysis oscillatory mode. The intensity molecular interactions was enthalpy which determined from calorimetric measurements using thermodynamic cycle. Strong interaction at resulted dominance “fluidic” rheological properties: prevalence modulus over storage high value angle. Meanwhile, poor favored “elastic” gel-like low values
