Nanoporous film generation from diblock copolymers has been used to direct the assembly of ligand-stabilized CdSe nanoparticles (see Figure). The number of particles forced into each pore is dependent on the concentration of the nanoparticles in solution. Further, the photoluminescence of the particles is maintained in the assembly process.
