The dissociation constant (K) of various molecular interactions was determined using a novel competition assay with binding magnetic relaxation nanosensors (bMRs). In this assay, changes in the magnetic relaxation of an aqueous suspension of the nanosensors facilitate the fast determination of K values using nanomolar protein concentrations.
