An imine-based approach was developed to prepare Janus gold nanoparticles (Janus AuNPs) having amine functionality on one patch of the surface and a polyethylene glycol unit on the other. This unique technique features covalent bonding as the force to immobilize AuNPs on the template, enabling direct modification of AuNPs in both water and organic solvents. Colloidal clusters were then obtained via electrostatic assembly of these Janus AuNPs with citrate stabilized AuNPs or AgNPs.
