Abstract: Provided is a particle immobilizing substrate that can be fabricated easily and in which inorganic nanoparticles are present in a nanometer-scale region. Also provided is a method capable of easily producing a substrate in which nanoparticles are arranged in a nanometer-scale region on a solid surface. The particle immobilizing substrate 1 comprises a substrate 2 and a plurality of inorganic nanoparticles 3 arranged on the substrate 2. The plurality of nanoparticles 3 are arranged in contact with each other within a region having a width (D1) of 1 μm or less on the substrate 2.

Abstract: Provided are: a structure comprising a diamond coating film having excellent surface smoothness; and a method for manufacturing the same. The present disclosure relates to a structure: including a substrate; diamond particles fixed to the surface of the substrate; and a coating film containing diamond particles stacked on the diamond particles and configured such that the diamond particles adjacent to each other in the height direction are in close contact with each other. The structure preferably has a configuration in which diamond particles adjacent to each other in the height direction are in close contact with each other due to Coulomb force.
