Summary:The percentage of large particles in the water suspension of diamond nanoparticles to a large extent determines the potential of using these suspensions in technology and medicine. It is demonstrated that there is an error in determining the percentage of large diamond nanoparticles in water suspensions using the dynamic light scattering (DLS) method to measure the size distribution of the particles. A method for labeling these suspensions based on supplementing the DLS measurements with recording of an optical spectrum in the visible region is proposed. The labeling allows one to perform more reliable determination of the percentage of large particles in a suspension.
