Influence of the size of the nanoparticles on their affinity (apparent dissociation constant) as determined by SPR. Dry size, measured by SEM and size in acetonitrile (in square brackets) measured by DLS. Inset: SEM of the 60 nm diameter MIP nanoparticles (the full field SEM can be seen in the Supporting Information, Figure S2). Error bars represent ± 1 s.d. (n = 3).
