This study presents a new model explaining anomalous diffusion in biological systems. It reveals how transient molecular interactions cause subdiffusion and nonergodicity, offering testable insights into disordered media.

Area of Science:

  • Biophysics
  • Physical Chemistry
  • Systems Biology

Background:

  • Spatiotemporal disorder is linked to anomalous nonergoditic diffusion in biological systems.
  • The microscopic mechanisms driving this phenomenon remain largely unknown.

Purpose of the Study:

  • To introduce a novel microscopic model for anomalous diffusion.
  • To elucidate the role of transient molecular interactions in inducing subdiffusion and nonergodicity.
  • To analyze the impact of binding partner density on diffusion properties.

Main Methods:

  • Developed a theoretical model simulating Brownian motion with variable diffusion coefficients.
  • Incorporated transient molecular interactions with diffusive binding partners.
  • Analyzed waiting time distributions and diffusion characteristics.

Main Results:

  • The model demonstrates subdiffusion and nonergodicity, mimicking heavy-tailed continuous time random walks.
  • Despite exponential waiting times, the system exhibits anomalous diffusion.
  • Diffusion properties are shown to depend on the density of binding partners.

Conclusions:

  • The proposed model provides a microscopic explanation for nonergodicity in disordered biological media.
  • The model's predictions are experimentally testable.
  • Offers a framework for understanding molecular diffusion in complex biological environments.
