From: Accuracy of the detection of binding events using 3D single particle tracking
The diffusion constant measured using single particle trajectories is underestimated when using short traces. The distribution of the measured D is obtained using all traces (a) or only traces longer than 40 points (b) or 80 points (c) for 53 nm x 16 nm GNRs in 95% glycerol. The center of the blue bar represents the expected value (calculated from Eq. 3); its width follows from the size dispersion measured from TEM images. The experimental D values are somewhat smaller than the expected ones and this difference, as well as the standard deviation, decrease for longer traces
