Controlled Incorporation of Particles into the Central Portion of Block Copolymer Rods and Micelles

Entropy-Driven Hierarchical Nanostructures from Cooperative Self-Assembly of Gold Nanoparticles/Block Copolymers under Three-Dimensional Confinement

“…1−5 Up to now, a number of strategies have been developed to fabricate the hybrid BCPs/NPs nanomaterials, including coprecipitation method, 6,7 heating−cooling processing, 8 electrostatic interaction approach, 9 directed supramolecular assembly, 10 interfacial instabilities of emulsion droplets, 11,12 and so forth. On the other hand, it has been reported that the neat BCPs can self-assemble into unique microphaseseparated nanostructures confined in emulsion droplets because the confinement effect can effectively break the symmetry of the structure, thus resulting in the nanostructures that are not available in the free systems.…”

Size- and distance-dependent excitation energy transfer in fluorophore conjugated block copolymer – gold nanoparticle systems

“…This process of centrifugation-washing-re-suspension was repeated thrice to ensure complete removal of any unbound block polymers from the re-suspended polymer-coated GNPs. Eisenberg et al [14,15]. had described that GNPs can be successfully incorporated in the core of the self-assembled of PS-b-PAA, where GNPs were stabilized mostly into the hydrophobic region produced by the selfassembled nanostructures.…”

“…Thiol chemistry has widely been exploited to modify the surface of AuNPs with synthetic polymers [2e4] and biomacromolecules [5e7]. The affinity of the diothioester end-groups for the gold surfaces have been utilized to link well-defined polymers (synthesized via RAFT polymerization method [8] [14,15].…”

Nanoparticle‐Loaded Cylindrical Micelles from Nanopore Extrusion of Block Copolymer Spherical Micelles

“…The most commonly employed methods include electrospinning, [ 23,24 ] template-assisted methods, [ 25,26 ] and cooperative self-assembly. [ 14,27 ] However, the in situ templateassisted methods have a prerequisite for electrostatic interaction or specifi c coordination of possible precursor metal ions to the polymer block while the cooperative selfassembly method of pre-formed nanoparticles together with block copolymers requires complicated controlling since the windows for cylindrical morphology in the phase diagram is relatively narrow. Despite tremendous efforts to explore the controlled self-assembly of nanoparticles and block copolymers, as far as we know, successful examples of simple yet effective method for the synthesis of hybrid cylindrical micelles are still limited.…”
