Figure 3. Simultaneous 3D multicolour microsphere diffusion.

Figure 3

a, One frame from recorded diffusion movie (Supplementary video 1), following diffusion of a red microsphere (marked in red) and a green microsphere (marked in green). The PSF is a multicolour 20 µm Tetrapod with a 45 degree rotation between the colours as in Fig. 2. Scale bar = 5 µm. b, Mean squared displacement (MSD) curves for the two microspheres. c and d, red microsphere and green microsphere 3D trajectories. Axes units are in µm. Colour scale encodes time in seconds.
