PROBLEM TO BE SOLVED: To provide a method for controlling apparent gravity and buoyancy of a particle by acting a magnetic field vertically and changing the strength and direction of the magnetic field, and to provide a method for manufacturing a particle film, which can manufacture a particle film where particles in the nanometer range are accumulated two-dimensionally, and a particle film manufactured by the method. SOLUTION: In this method for controlling the positions of particles, a magnetic field is added to a solvent in which particles are dispersed, and the positions of the particles in the solvent are controlled by the strength and direction of the magnetic field. In this method for manufacturing a particle film, a solvent in which particles are dispersed is applied to a substrate, and the solvent is evaporated by using the method for controlling the positions of the particles with respect to the liquid level of the solvent by the strength and direction of the magnetic field, thereby accumulating the particles two- dimensionally. |
