Discrimination of diffusion models by ensemble-averaged microfluorimetric methods: Spatially resolved fluorescence recovery after photobleaching Lifetime-based raster image correlation spectroscopy

Abstract

In this work, the Continuous Time Random Walk (CTRW) technique has been applied to simulate both free and anomalous diffusion. This framework offers a straightforward recipe to simulate both free and anomalous diffusion. By means of exponentially distributed waiting times, which have a finite expectation value, free diffusion is simulated. When the waiting time distribution does not have a finite expectation value, anomalous diffusion is obtained....
