介绍了一种金属氧化物表面功能化的新方法，特别是纳米颗粒。这一过程包括设计稳定的配体，这些配体强烈结合到金属氧化物的表面，并可以通过点击化学进行进一步的化学修饰，包括小分子和聚合物，以获得具有定制功能的金属氧化物表面。这种纳米粒子很稳定，很容易分散在极性和非极性的溶剂中，这一特性由配体控制。用透射电子显微镜、热重分析、傅立叶变换红外光谱和核磁共振对所合成的纳米粒子进行了表征。
A new means for functionalizing metal oxide surfaces, specifically nanoparticles, is demostrated. This process involves the design of stable ligands that bind strongly to the surface of metal oxides and can undergo further chemical modification via click chemistry, with both small molecules as well as polymers, to yield metal oxide surfaces with tailored functionality. The nanoparticles are stable and easily dispersed in both polar and nonpolar solvents, a property that is controlled by the ligand. The resultant nanoparticles were characterized by TEM, TGA, FTIR, and NMR.
