Chemically modified nanodiamond particles, their production method, and MRI contrast agents using them

摘要

PROBLEM TO BE SOLVED: To provide chemically modified nanodiamond particles having high dispersibility. A chemically modified nanodiamond particle contains a complex consisting of a metal ion and a ligand formed by a bond between the nanodiamond particle into which a carboxyl group has been introduced and a chelating agent.
