Receptor Diffusion on a Membrane
Track an ensemble of membrane receptors and change the anomalous diffusion exponent
α. Normal Brownian diffusion has α = 1, subdiffusion has α < 1,
and persistent or superdiffusive motion has α > 1. The trajectories are generated
so that ⟨r²(t)⟩ = 4Dtα.
α < 1 subdiffusion · α = 1 Brownian · α > 1 superdiffusion
Single-Receptor Trajectories
Choose α and run trajectories
MSD Scaling: slope = α
How to read the simulation:
α = 1 gives ordinary Brownian diffusion. Values below 1 produce anti-persistent,
subdiffusive trajectories. Values above 1 produce increasingly persistent,
superdiffusive motion, approaching ballistic transport as α approaches 2.
