✦ Synopsis

Surface diffusion coefficients (D) have been measured for gold nanorods suspended in water on planar gold substrates. The Figure shows the composite image of sequential optical micrographs at 15 s intervals. The variation of D is more dependent on rod length than predicted by the Stokes–Einstein equation, consistent with a frictional interaction between the rod and the surface.
