Kinetic Binding Values for the Association and Dissociation between Nanoclusters and VCAM-Immobilized Substrate as Determined by SPR Spectroscopy^a

morphology of targeted cluster	association rate constant $k_{\text{a}}$ (M−1 s−1)	dissociation rate constant $k_{\text{d}}$ (s−1)	binding constant $K_{\text{A}}$ (M−1)
spherical	1.0	1.3 × 10−3	7.7 × 102
worm-like	14.7	1.5 × 10−5	1.0 × 106

^aValues are given per molar concentration of iron.
