Rigidity modulus of magnetic fibrin hydrogels for increasing concentration of magnetic nanoparticles (MNP). Black square symbol, non-magnetic hydrogel. Bullet symbols, magnetic hydrogels gelled in the absence of magnetic field. Triangle symbols, magnetic hydrogels gelled for the first 5 min under the application of a magnetic field of 48.6 kA m−1. The modulus of the non-magnetic hydrogel is 75 Pa. Reprinted by permission from Springer Nature from [47].
