Three-dimensional architectures,

The use of color graphics is also an effective means for displaying chemical stmctures. This method is far better than typesetting the three-dimensional architecture of complex multimolecule assembly (112). For developing in-house CAD software programs, the three-dimensional, sohd-modeling capabiUties of SdverScreen can also be utilized either in monochrome or color for constmction of such stmctures (113).

Crystalline phases (truncated octahedra) of 5 nm silver particles, thiolate protected as well, have been detected by means of high-resolution transmission electron microscopy (HRTEM) [26-28]. Three-dimensional architectures of 5-6 nm thiolate-stabilized gold particles have also been described [29]. Several other reports on 3D superlattices of metal nanoparticles have become known during the last few years [30-33].

A vital activity of the chemical sciences is the determination of structure. Detailed molecular structure determinations require identifying the spatial locations of all of the atoms in molecules, that is, the atomic distances and bond angles of a species. It is important to realize that the three-dimensional architecture of molecules very much defines their reactivity and function. However, molecules are dynamic, a feature that is not reflected by static pictures. This last point requires further explanation. Because the atoms in all molecules move, even in the limit of the lowest temperatures obtainable, molecular structures really describe the average position about some equilibrium arrangement. In addition, rotations about certain bonds occur freely at common temperatures. Consequently, some molecules exist in more than one structure (conformation). Some molecules are so floppy that structural characterizations really refer to averages among several structures. Yet other molecules are sufficiently rigid that molecular structures can be quite precisely determined. 

The supramolecular game involves only one brick instead of two, so the number of degrees of freedom is reduced. The autoassembling process which takes place between Jt-carriers governs the final three-dimensional architecture of the material. 

The combination of dyes with microporous materials opens-up a way to develop selective chemosensors microporous zeolites with an anchored squaraine 27 (Fig. 13) and some other types of dyes can be used as chemosensors for the chromogenic discrimination of amines [75], These dye-zeolite hosts are expected to be promising sensor materials allowing the visible discrimination of selected target guests by size and/or polarity within families or closely related molecules. It was found that the response of the solid to amines was basically governed by the three-dimensional architecture of the solid material.

Genomics is the complete understanding of all the locations and sequences in the tens of thousands of genes in humans. What are the functions associated with these sequences What proteins are made from these gene sequences, what are their onedimensional strings and three-dimensional architectures when folded appropriately Can we use this knowledge to diagnose diseases, and to make material to cure these diseases ... 

It may be possible to build up a two- or three-dimensional architecture composed of proteins using avidin and biotin-labeled enzymes as building blocks. If we use enzymes tagged with more than two biotin residues, an enzyme multilayer illustrated in Figure 10 would be constructed because avidin contains four biotin-binding sites per molecule. Fortunately, the biotin-binding sites are located in two pairs on the opposed faces of the avidin molecule. Thus, the use of biotin-labeled enzyme... 

One of the most important objectives of nanoscience and nanotechnology is to take advantage of the unique properties of nanomaterials. Nanomaterials can be synthesized from the assembly of individual Au NPs to give more or less ordered nanostructures possessing one-, two- or three-dimensional architectures. As described in the final section of this chapter, these Au nanomaterials can be applied in different fields such as optics, electronics, sensing, catalysis, biology-related applications, and so on.
