Shear modulus of the continuous matrix of magnetic tissue substitutes, as calculated with Eq (3).

a Experimental groups: M-MF0: magnetic tissue substitute gelled in the absence of a magnetic field; M-MF16, M-MF32 and M-MF48: magnetic tissue substitutes gelled during application of a 16 kA m-1, 32 kA m-1 or 48 kA m-1 field, respectively.
Note the mean value of the shear modulus in control samples without particles (Ctrl-MF0 to Ctrl-MF48), Gcontrol = 101 ± 10 Pa. Uncertainties were estimated according to the theory of error propagation.
