  • Preparation method and secondary dispersion of monodisperse aminated manodiamond colloid solution and its application in cellular biomarking
    Patent number: 11105811
    Abstract: A preparation method and secondary dispersion of monodisperse aminated Nanodiamond colloid solution and its application in cellular biomarking are provided. Preparation method comprise: mixing purified Nanodiamond powder with ammonium chloride and sodium chloride, placing the mixture in a ball mill for dry ball milling, washing the ball-milled mixture with deionized water, and performing ultrasonic dispersion and centrifuging to obtain the monodispersed aminated Nanodiamond colloid solution. Secondary dispersion process comprising: drying aminated Nanodiamond colloid solution to obtain aminated Nanodiamond powder, re-dispersing the powder in DMSO (dimethyl sulphoxide), deionized water, ethanol, DMF (dimethylformamide) or other solvents with ultrasonic or shearing processing. The aminated Nanodiamond has high yield and good monodispersity.
