Title: Scale-dependent diffusion of spheres in solutions of flexible and rigid mean square displacement and autocorrelation function for FCS and DLS measurements
Abstract: We present a theoretical description of diffusion of a sphere in polymer The depletion layer around the sphere affects its motion and to scale-dependent diffusion. We propose the model of walking diffusion. Although it is different from anomalous diffusion, show that the experimental data generated by this process may have characteristic of anomalous diffusion. We give analytical for the autocorrelation functions describing this type of in: i) dynamic light scattering experiments and ii) fluorescence spectroscopy experiments. We compare our results to existing data for polyethylene oxide, fd-virus, and F-actin solutions.
