Abstract: The present invention provides a method for producing a substance with a modified carbon allotrope surface that can suppress or prevent uneven distribution, uneven orientation, and the like of a structural analysis target substance in a structural analysis by cryo-electron microscopy. A method for producing a substance with a modified carbon allotrope surface of the present invention includes: the step of surface-treating by reacting a carbon allotrope surface with a halogen oxide radical, wherein the carbon allotrope surface is modified by the surface-treating.
