More Information
Summary:Provided are: a polyglycerin-chain surface-modified nanodiamond having excellent dispersibility in a low-polarity solvent; and a method of producing the polyglycerin-chain surface-modified nanodiamond. A surface-modified nanodiamond 1 includes a nanodiamond particle 2 and a surface-modifying group 3 that surface-modifies the nanodiamond particle 2, the surface-modifying group 3 having a polyglycerin chain in which a hydrogen atom of at least some of the hydroxyl groups in the polyglycerin chain is substituted by a monovalent organic group.
