Hierarchical self-assembly of inorganic nanoparticles mediated by organic macromolecules

The hierarchical self-assembly of inorganic nanoparticles mediated by the tailed organic macromolecules has been reviewed. The organic macromolecules used for the mediators include the synthetic polymers and the biopolymers. Up to now, the polymers with hydrogen-bond recognition functionality, polyelectrolytes, block copolymers and dendrimers have been developed as synthetic polymers for the assembly of the inorganic nanoparticles. At the same time, DNA, amylose and proteins also present the impressive ability for the ordered aggregation of inorganic nanoparticles. It is necessary for the hierarchical assembly of inorganic nanoparticles to modify them to afford their surfaces tailored functionality, for example hydrogen-bond recognition groups, positive charges, negative charges, and so on, which can recognize with the organic mediators. This research field is very essential for the construction of advanced functional materials and biomimetic materials.
