Janus Particles with Controllable Patchiness and Their Chemical Functionalization and Supra molecular Assembly

摘要

Janus particles constitute a type of soft matter with different physicochemical properties on opposite sides of the particles. As highlighted by de Gennes in his Nobel lecture in 1991, such asymmetric particles offer unique properties that are impossible to attain with homogeneous or symmetric materials. Janus particles have been used as building blocks for the assembly of complex nanostructures, as two-phase stabilizers, and for applications in nanomotors, gene delivery, imaging probes, and electronic displays.
