Fig. 4: Molecular composition of the network sets its activity and elasticity.
From: Competing instabilities reveal how to rationally design and control active crosslinked gels
Activity (blue curves) and shear modulus (orange curves) when varying a ATP concentration, b motor cluster concentrations, and c PRC1 crosslinker concentrations. Active and elastic stresses are inferred from fitting the theoretical model to the experimental phase diagrams (as described in the SI sections 2.4 and 3). When the activity is above (resp. below) the dashed line, the network bends in-plane (resp. buckles out-of-plane). \({\mu }_{0}\) is estimated from bulk rheology experiments by the authors from ref. 38 (see SI section 3.4), while the ratios \({\zeta }_{0}/{\mu }_{0}\), K0\({/\kappa }_{0}\), and, \({\kappa }_{0}/{\zeta }_{0}\) are fitted parameters.
