Rheological properties of magnetic biogels
We report an experimental and theoretical study of the rheological properties of magnetic biogels
consisting of fibrin polymer networks with embedded magnetite nanoparticles, swollen by aqueous solutions.
We studied two types of magnetic biogels, differenced by the presence or absence of an applied magnetic field
during the initial steps of cross-linking. The experiments demonstrated very strong dependence of the elastic
modulus of the magnetic biogels on the concentration of the magnetic particles. We finally developed some
theoretical models that explain the observed strong concentration effects.This study was supported by projects FIS2013-41821-R (Plan Nacional de Investigación Científica, Desarrollo
