Biological templates that have been successfully used include self-assembled cylindrical particles of the Tobacco Mosaic Virus (TMV). The surface charge of the virus was chemically controlled thus enabling metallisation to be selectively performed on the outer cylindrical surface or in the inner capillary-like cavity.
Recent work has involved using chiral amphiphilic molecules that self-assemble into helical ribbons & cylindrical tubules to produce viscoelastic fluids & gels. Complex fluids are also used to synthesise & self-assemble higher-order nanoparticle-based structures.
