Abstract
The present invention discloses a method for separating nanoparticles with a controlled number of active groups is disclosed. First, a plurality of nanoparticles are provided, wherein the surface of the nanoparticle comprises a plurality of first active groups. Next, a plurality of functional ligands are provided, wherein the functional ligand comprises at least one second active group and at least one third active group. Then, a binding process is performed to bind the nanoparticle with the functional ligand, wherein the first active group connects with the second active group. After the binding process, a separation process is performed to isolate a plurality of nanoparticles with a controlled number of the third active groups. The controlled number is integers from 0 to 10.
