title: Magnetic-force quartz crystal microbalance for the detection of chemical interactions.
abstract: The magnetic-force quartz crystal microbalance (QCM) method was attempted for the dynamic evaluation of chemical interactions.  Thiol-modified magnetic particles bound to a QCM gold electrode of less than three layers were pulled by a magnetic force, and the dissociation dynamics of the magnetic particles was measured based on the change in the weight as a function of time under different temperatures.  From an analysis of the dissociated layers and the activation energy for the dissociation, the chemical interactions between particles were evaluated.
