通过十八胺与纳米金刚石颗粒表面共价连接，合成了疏水性蓝色荧光纳米金刚石。该材料易于分散在疏水性溶剂中，形成透明的胶体溶液，可用于需要纳米金刚石在燃料、聚合物或油中稳定分散的应用。十八胺修饰的纳米金刚石的明亮的蓝色荧光为其作为无毒量子点类似物用于生物系统的细胞膜和其他疏水组分的生物医学成像开辟了新的途径。类似的表面改性可用于其他碳纳米颗粒。
Hydrophobic blue fluorescent nanodiamond was synthesized by covalent linking of octadecylamine to the surface of nanodiamond particles. The material is easily dispersible in hydrophobic solvents, forming a transparent colloidal solution, and can be used in those applications where stable dispersions of nanodiamond in fuels, polymers or oils are required. Bright blue fluorescence of the octadecylamine-modified nanodiamond opens up new avenues for its use as a non-toxic quantum dot analogue for biomedical imaging of cellular membranes and other hydrophobic components of biological systems. Similar surface modification can be used for other carbon nanoparticles.
