Our investigations of motor dynamics propelled by ECRs use a coarse-grain microscopic description of the entire system. We consider a colloid with two types of enzymes coated on its surface. One of the enzymes $E_0$ is inert, while the other, enzyme $E_1$ (mimicking $G{O}_x$), catalyzes the fuel $A$ (mimicking glucose) into an intermediate product $I$ (mimicking $H_2{O}_2$). Such Janus colloid has been fabricated in recent experiments. In addition, we construct a special structure by grafting another enzyme, $E_2$ (mimicking $Cat$), onto the outer layer of $E_1$, which catalyzes the intermediate product $I$ into the final product $B$ (mimicking $O_2$). $A$ schematic diagram of the motor configuration is presented in Figure 1. The nanomotor is operated by a diffusiophoretic mechanism where the ECRs on the active enzymes produce concentration gradients that drive propulsion. The solution in which the motor moves contains fuel $A$ as well as products $I$ and $B$ particles. These species interact with the motor through intermolecular potentials and determine how the motors move in the presence of chemical gradients produced by the motors themselves. Additional information concerning the motor configuration and the simulation is given in the Section 3.

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
