Active motion of synthetic nanomotors in filament networks
The collective behavior of chemically powered nanomotors in complex filament networks is investigated. The synthetic motors are small oligomers and use self-diffusiophoresis for their active motion. Much like biological molecular machines, these motors attach to the filaments, which highly suppress...

| description | The collective behavior of chemically powered nanomotors in complex filament networks is investigated. The synthetic motors are small oligomers and use self-diffusiophoresis for their active motion. Much like biological molecular machines, these motors attach to the filaments, which highly suppress orientational Brownian motion, and move along them. The collective motion is influenced by structure of the network and the forces that bind the motors to the filaments; it is characterized by strong clustering, especially near cross-links in the network, and differs substantially from that in a simple fluid phase where only weak clustering occurs. The features of the collective behavior are quantitatively examined through computations of the effective binding potentials and the dynamics of probe oligomers. The results are relevant for applications in the biological and materials sciences involving complex natural and synthetic networks activated by small chemically powered motors. |
