Rheological properties of magnetic biogels Zubarev, Andrey Bonhome Espinosa, Ana Belén Alaminos Mingorance, Miguel García López-Durán, Juan De Dios López López, Modesto Torcuato 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. 2021-04-05T08:40:05Z 2021-04-05T08:40:05Z 2019 info:eu-repo/semantics/article Arch Appl Mech (2019) 89:91–103 http://hdl.handle.net/10481/67778 10.1007/s00419-018-1450-2 eng info:eu-repo/semantics/openAccess
