Organically functionalized POMs (see for review [144]) are useful hybrid nanobuilding blocks to obtain hybrid organic-inorganic structures [139 and references therein].

Plant Viral Capsids as Programmable Nanobuilding Blocks... 

Altogether, plant viruses and especially CPMV display a number of features to be exploited for nanobiotechnology and can be regarded as extremely robust, monodisperse nanobuilding blocks. 

In 2002, for the first time, CPMV was regarded as an addressable nanobuilding block [79]. First, experiments were conducted in order to test selective chemical derivatization of wild-type virions later, several mutant particles were made, such as cysteine mutants [80] and histidine mutants [81]. Different bioconjugation strategies were applied and a set of biological and organic and inorganic chemical molecules have been attached to CPMV. 

In the above two independent studies, the feasibility of CPMV as a nanobuilding block for chemical conjugation with redox-active compounds was demonstrated. The resulting robust, and monodisperse particles could serve as a multielectron reservoir that might lead to the development of nanoscale electron transfer mediators in redox catalysis, molecular recognition, and amperometric biosensors and to nanoelectronic devices such as molecular batteries or capacitors. 

In summary, the feasibility of CPMV particles as nanobuilding blocks for the controlled fabrication of arrays on solid supports has been demonstrated and different immobilization strategies were found to be applicable. The introduction of functional molecules in the one-, two-, or three-dimensional arrays of uniform nanoparticles may provide potential for the development of novel functional devices on the nanoscale. 

Directed Assembly of Nanobuilding Blocks on Planar Substrates... 

In the next few years, there will be many exciting developments related to NEMS devices. In particular, replacing the current chemically driven molecular machines with those stimulated by optical or electrical pulses - dramatically extending the range of applications. With so many possible nanobuilding blocks at our disposal, the scope of devices and resultant applications is limited only by our imaginations -an exciting area of discovery awaits ... 

These interesting POSS features, briefly mentioned above, have motivated this work to critically review recent developments in the syntheses of POSS polymer materials to form POSS nanocomposites. The work further examines the properties of POSS nanobuilding blocks that can otherwise be used for developing polymeric nanocomposites. In particular, the syntheses of POSS cages, monomers containing POSS cages, POSS-dendrimers cores, POSS-containing polymers and POSS nanocomposites are covered in details. It should be emphasized that the assessment of the relationship between the... 

The inorganic nanobuilding blocks were found to be attached to the hard segments and greatly enhanced the tensile modulus and strength of the elastomer. Haddad et al. [Ill] and Fu et al. [128] have similarly provided works on condensation polymerization. The well-defined functionalized POSS have been prepared by the hydrosilylation reaction of terminal olefins with octahy-dridosilsesquioxane or direct hydrolytic condensation reactions of silanebearing compounds [75,100,129]. However, clear explanation on the mechanism of direct hydrolytic condensation reaction has not been explored yet. 

The aniline groups of octa(aminophenyl)silsesquioxane (OAPS) offer versatility both as reaction sites to which other nanobuilding blocks can be... 

One of the most recent trends is to use nanobuilding blocks, or crystal tectonics. 106,187,188 The idea is to use a pre-formed inorganic fragment with the desired porous or catalytic properties which is then simply immobilized into a matrix, as, for example, in POSS or titanium alkoxide fragments.189 Alternatively, the fragment may be coordinated to the surfactant template.189,190 Incorporation of metallocene catalyst-terminated silanol dendrimers into silica was achieved through sol gel processing methods.191...
