Self-assembly of Brownian motor by reduction of its effective temperature

TL;DR

This paper investigates how Brownian motors self-assemble by reducing their effective temperature, revealing a general mechanism for motor emergence that has implications for biological systems and nanodevice fabrication.

Contribution

It introduces a novel self-assembly mechanism for molecular motors based on effective temperature reduction, linking chemotaxis and the emergence of living-like systems.

Findings

Motors tend to minimize their effective temperature and conformational change rate.

The mechanism explains the emergence of motor-like motion in fluctuating environments.

Implications for nanodevice mass fabrication and understanding biological motility.

Abstract

Emergence, optimization and stability of a motor-like motion in a fluctuating environment are analyzed. The emergence of motion is shown to be a general phenomenon. A motor converges to the state with the minimum of effective temperature and with the corresponding minimum in the rate of conformation changes similarly as some stochastic processes converge to the states with minimum diffusion activity. This mechanism is important to bacterial foraging (chemotaxis). This work, therefore, raises an analogy between chemotaxis and the emergence of living-like systems. The implications include the deviation of stable natural or artificial machines from the minimum entropy production principle, with a novel self-assembly mechanism for the emergence of the first molecular motors and for mass fabrication of the future nanodevices.
