(a) Projected distribution ρ(dp) of particle diameters for biotinylated polystyrene spheres before and after incubation with NeutrAvidin. The width of the distribution, σd, reflects the population polydispersity in diameter. The difference, Δρ(dp), between these distributions is consistent with a statistically significant increase of Δdp = (1.4 ± 0.1) nm in the mean particle diameter. (b) Analogous data for IgG binding to spheres coated with protein A shows an increase of Δdp = (3.2 ± 0.4) nm.
