Extended Data Fig. 3: Contraction force of printable active network in experiment and simulation.
From: A printable active network actuator built from an engineered biomolecular motor
a, Time evolutions of bending force of the flexible cantilever under various concentrations of K465m13. After reaching maxima, in many cases, the displacement was suddenly dropped due to rupture of the active network. b, Maximum contraction force produced vs. K465m13 concentration, tubulin concentration, and mean microtubule length. c, Contraction force steadily increased with time until the active network ruptured, which is in agreement with the experimental results shown in a. d, The maximum force increased with (left) motor density; (middle) the number of nodes; and (right) node radius. These results agree with the experimental results in b, assuming that K465m13 concentration, tubulin concentration, and microtubule length correspond to motor density, the number of nodes, and the node radius, respectively. In the node radius simulation shown in (right), the product of the number of the nodes and the radius of individual nodes was kept constant to be consistent with the experimental condition of a constant tubulin concentration. Data points are represented as mean ± s.d. in b (n = 3) and d (n = 5).
