abstract = {We investigate depletion interactions near a wall caused by
polydisperse silica-coated gibbsite platelets, using total
internal reflection fluorescence microscopy (TIRF) to
characterize the sphere-wall interaction potential. As no
theoretical model for polydisperse platelets exists, we
extend a model for monodisperse depletant cylinders by
assuming negligible thickness and averaging over the disc
size distribution, finding nearly perfect matching with
experimental data. The resulting averaged depletion
potentials have, as predicted by the extended model, the
same depth as monodisperse potentials, but differ in range
and shape according to the size distribution. We compare
mean particle sizes and standard deviations derived by TIRF
with results from TEM measurements.},
