Abstract
A counting method includes aggregating particles in a sample by action of first-direction dielectrophoretic force, dispersing the aggregated particles by action of second-direction dielectrophoretic force, which is different from the first-direction dielectrophoretic force, capturing a dispersion image including the dispersed particles, and determining the number of particles on the basis of the dispersion image.
