Harmonic analysis of anomalous diffusion with FITC-polydextran (2 MDa) in 22 mg/mL HA. Fluorescence recovery of the first, second, and third harmonics are fitted to a modified Mittag-Leffler function to recover the anomalous diffusion coefficient (D = 1.124 ± 0.008 μm^μ/s^2α/μ), the subdiffusion parameter (α = 0.571 ± 0.003), and the Lévy flight parameter (μ = 1.173 ± 0.006). The recovered parameters reveal subdiffusive and Lévy flight behavior in the sample. The reported uncertainties are the SDs in the fit. To see this figure in color, go online.
