Abstract

Anomalous diffusions is emerging as a key property in cell membrane dynamics because it is both a probe of membrane microstructure and because it is has a major influence on reaction kinetics within the membrane. A microscopic model for protein trajectories incorporating immobilising trapping-events and generalised Langevin dynamics, describing the motion of a Brownian particle acted upon by a stochastic force with long-range temporal correlation, will be formulated and examined in analytical studies. It is hypothesised that such a model predicts the coexistence of normal, anomalous and time- dependent restricted diffusion, non-Gaussian transport characteristics and the occurrence of transitions from anomalous to normal to anomalous diffusion, in accordance with experimental observations but in stark contrast with current modelling approaches.
