Highly ordered mesostructures of tin oxide have been obtained via the block-copolymer-assisted assembly of crystalline tin oxide nanoparticle sols. The 3.5 nm tin oxide nanoparticles obtained using low-temperature synthesis can be dispersed without the use of any stabilizers and are assembled via an evaporation-induced self-assembly (EISA) process (see Figure).
