“…One dimensional confinement of colloidal particles is possible within groove and channel patterns of a substrate, [69] but can be extended to larger length scales by confining particles within polymer nanofibers. The extent of guiding by confinement depends on the particle-polymer interactions.…”

Colloidal Assembly: The Road from Particles to Colloidal Molecules and Crystals

Colloidal particles may be considered as building blocks for materials, just like atoms are the bricks of molecules, macromolecules, and crystals. Periodic arrays of colloids (colloidal crystals) have attracted much interest over the last two decades, largely because of their unique photonic properties. The archetype opal structures are based on close-packed arrays of spheres of submicrometer diameter. Interest in structuring materials at this length scale, but with more complex features and ideally by self-assembly processes, has led to much progress in controlling features of both building blocks and assemblies. The necessary ingredients include colloids, colloidal clusters, and colloidal "molecules" which have special shapes and the ability to bind directionally, the control over short-range and long-range interactions, and the capability to place and orientate these bricks. This Review highlights recent experimental and theoretical progress in the assembly of colloids larger than 50 nm.

“…Some of the simpler packings that we have tabulated have been realised in experiments with dry foams [4][5][6][7][8] and more recently using wet foams [9]. Similar, monolayer arrangements have also been observed in a biological microstructure [10], by confining colloids in micro channels [11][12][13][14] and encapsulating fullerenes within nanotubes [15][16][17].…”

We show that the optimal packing of hard spheres in an infinitely long cylinder yields structures characterised by a screw symmetry. Each packing can be assembled by stacking a basic unit cell ad infinitum along the length of the cylinder with each subsequent unit cell rotated by the same twist angle with respect to the previous one. In this paper we quantitatively describe the nature of this screw operation for all such packings in the range 1 ≤ D/d ≤ 2.715 and also briefly discuss their helicity.

“…Die erste wissenschaftliche Veröffentli-chung über Opalimitate erschien 1989. [25] Die [38] sind Ketten aus Kugeln oder auch kompliziertere seilartige Anordnungen, [39] die ebenfalls interessante optische Effekte zeigen. Monoschichten aus sphärischen Nanopartikeln können leicht hergestellt werden [40] und entsprechen zweidimensionalen photonischen Kristallen, die gleichfalls typische photonische Effekte aufweisen.…”

Die Schönheit von Opalen beruht auf einer dichten, hochgeordneten Packung von SiO2‐Kugeln mit einem Durchmesser von einigen hundert Nanometern. Solche geordneten Nanostrukturen sind typische Beispiele für so genannte photonische Kristalle, die sowohl durch die bekannten Mikrostrukturierungsmethoden als auch durch Selbstorganisation hergestellt werden können. Opale stehen für den Selbstorganisationszugang zu diesen strukturierten Medien, die zu neuen Materialien in der Photonik, Photokatalyse und anderen Gebieten führen können. Die Selbstorganisation hat viele Arten von Defekten zur Folge, die zu den überraschenden und sehr individuellen Erscheinungsformen natürlicher Opale führen, aber auch Schwierigkeiten bei der technischen Anwendung von Opalsystemen verursachen.
