Block copolymer assemblies have attracted great attention
due to their potential applications in the fields of drug
delivery, targeting therapy, medical diagnosing and imaging.
Three dimensional (3D) confinement, which can break the
symmetry of a structure, has proven to be a powerful route to
tailor the morphologies of block copolymer particles. Particle
shape and internal structure can thus be tuned by using the
supramolecular strategy or tailoring the interfacial interaction
of the particles with the dispersion medium. We will introduce
the generation of the nano-objects with well tunable shapes by
taking advantage of 3D confined assembly and supramolecular
chemistry. Particles with various internal structures can be
obtained due to the 3D soft confinement in emulsion droplets.
Moreover, we will show that selective disassembly of the
structured particles will give rise to mesoporous particles or
nano-objects with unique shapes, potentially useful for drug
delivery, bio-imaging, separation and diagnostics.
