Fig. 14 Structural control of critical hierarchical design parameters (CHDPs), namely, size, shape, surface chemistry, flexibility/rigidity, composition, and architecture, required for bottom-up synthesis of higher nanostructural complexity manifesting atom mimicry...

Very recently, important examples describing the chemical combination and assembly of these proposed hard and soft nano-element categories (i.e., superatoms) as described in Fig. 24 have now appeared in the literature and are referred to as nanoscale atom mimicry at the nanoscale. In each case, our early concept has been fulfilled and validated by these authors, who have referred to these nanoscale... 

As a second illustrative aspect of the boron/carbon connection, we consider the dicarbollide ion, C2B9H112-, which can be pictured as derived from Bi2Hi22- by removing one BH(t) vertex and replacing two adjacent borons of the exposed pentagonal face by carbon atoms, as shown in Fig. 3.116. This ion exhibits remarkable electronic mimicry of the cyclopentadienyl ion (C5H5-, Section 3.3.2), forming similar coordination and sandwich complexes with many metallic species.162... 

Finally, the CG and CD atoms of the arginine residue of the tail occupy the positions of C3 and C4 of the + 1 GlcNAc residue. Thus, this arrangement may be considered structural mimicry, and one side of the - 1 sugar residue as well as part of the + 1 sugar residue are mimicked effectively by the peptide. 

Vector Maps and Conformational Mimicry. Often, one is more interested in accessing the directionality of potential interaction rather than simply looking for overlap of atoms such as the basic nitrogen. In this case, for example, one is interested in determining both the locus of the lone pair of the nitrogen...

P-450 mimics to transfer nitrogen atoms, not just oxygen.Expansion of this approach to enzyme mimicry is still underway.
