“…[164] Under appropriate conditions, the mobility at the air/water interface allows induction of hexagonally packed arrays of ferritin to form, which can be subsequently transferred to a solid support. [165] This protocol has been adapted to transfer hexagonally packed arrays of recombinant glutaraldehyde crosslinked apoferritin to solid supports. [166] The same technique has also been used to construct iron and indium core arrays on TEM grids and arrays of iron oxide nanoparticles on silicon.…”

Materials scientists increasingly draw inspiration from the study of how biological systems fabricate materials under mild synthetic conditions by using self‐assembled macromolecular templates. Containerlike protein architectures such as viral capsids and ferritin are examples of such biological templates. These protein cages have three distinct interfaces that can be synthetically exploited: the interior, the exterior, and the interface between subunits. The subunits that comprise the building blocks of these structures can be modified both chemically and genetically in order to impart designed functionality to different surfaces of the cage. Therefore, the cages possess a great deal of synthetic flexibility, which allows for the introduction of multifunctionality in a single cage. In addition, hierarchical assembly of the functionalized cages paves the way for development of a new class of materials with a wide range of applications from electronics to biomedicine.

“…Another method, i.e., the air-water interface method, was found to be more suitable for fabricating larger and uniform 2D crystals. [125][126][127] In principle, an NP-ferritin solution (1 µL) is injected into the bottom of a 2% sucrose solution with cadmium ions (200 µL), which has a higher density than the NP-ferritin solution. The ferritin solution can rise up to the air-liquid interface by buoyancy and spread at the solution surface [ Fig.…”

Virus particles and proteins are excellent examples of naturally occurring structures with well-defined nanoscale architectures, for example, cages and tubes. These structures can be employed in a bottom-up assembly strategy to fabricate repetitive patterns of hybrid organic–inorganic materials. In this paper, we review methods of assembly that make use of protein and virus scaffolds to fabricate patterned nanostructures with very high spatial control. We chose (apo)ferritin and tobacco mosaic virus (TMV) as model examples that have already been applied successfully in nanobiotechnology. Their interior space and their exterior surfaces can be mineralized with inorganic layers or nanoparticles. Furthermore, their native assembly abilities can be exploited to generate periodic architectures for integration in electrical and magnetic devices. We introduce the state of the art and describe recent advances in biomineralization techniques, patterning and device production with (apo)ferritin and TMV.

“…In addition, the methods to obtain arrays of, the major cellular iron-strage protein (Fig. 6.22a), have been intensely studied and it has become possible to make large 2D crystals or arrays of at an air-water interface [106][107][108]. Based on these previous results, he transferred a two-dimensional array of iron-oxide loaded molecules formed by self-assembly at an air-water interface onto a hydrophobic silicon (Si) surface and eliminated the protein shell of the molecule, apoferritin, with 1 h heat-treatment at 500 ı C under nitrogen atmosphere (Fig.…”

This paper reviews recent progress of chemical preparation of metal nanoparticles and their assembly formation processes. Various metal and semiconductor nanoparticles have been intensively studied according to their unique properties controlled by their sizes. One predicted that nanoparticles with the diameter in the range of 1-10 nm would display specific electronic structures, which reflect the electronic band structure ("quantum size effect"). For example, some metal nanoparticles in these sizes show photoemission. The melting points of these nanosized metal particles are extremely lower than the bulk. Gold, silver, and copper nanoparticles show their specific absorption, plasmon absorption, which is also used for surface plasmon resonance (SPR). To use their unique properties as materials, not only the control of their structures and sizes but also controlled formation of low dimensional assembly of these nanoparticles are highly important. Ordered assembly of such nanoparticles give their unique and interesting functions, such as sensing, electron tunneling, information stage and so forth. From this viewpoint, we would like to discuss hereafter a couple of fundamental preparation processes of metal nanoparticles and various assemble techniques.
