Another advantage cited for organic electronics is their perceived low environmental impact and high expected consumer safety. This assumption is generally based on the notion that plastics are easily recycled and are considered safe to humans and animals. However, the materials used are often completely new compositions with poorly understood health and safety attributes. The assumption that all plastics are completely safe for humans is inaccurate, as is exemplified by recent concerns about the toxicity of polyvinyl chloride (PVC).39 In contrast, most inorganic nanoparticle materials are already on the consumer market and have extensive historical data on their safety in a variety of applications. Some materials, such as zinc oxide, are even considered reasonably safe for ingestion and therefore are commonly used in food and cosmetics. However, the health effects and interactions of nanoparticles on the human body are still a topic of debate.40... 

Considerable interest also has been directed at the use of multicomponent composites where, in theory, the most useful properties from each phase can be realized in the whole. This includes metallodielectric structures where a metallic phase imparts, for example, a high index or more exotic effect (e.g., plasmon resonance) and a low-loss or property-tunable dielectric phase. The dielectric phase can be ceramic or polymeric and also has included ferroelectric polymers, embedded nanoparticles, and organic/inorganic hybrids. ... 

Nanoporous carbon with narrow pore-size distribution can be prepared directly via a one-step nanocasting technique by carbonization of cyclodextrin-silica organic-inorganic hybrid composite.[260] The method consists of preparing a cyclodextrin-templated silica mesophase via soft chemistry, followed by direct carbonization of the occluded cyclodextrins. The nanocasting procedure provides granules (in millimeter scale) or monoliths (in centimeter scale). Cyclodextrins can be employed not only as structuredirecting templates but also as carriers for metal nanoparticle precursors. 

Some of the sugar- and peptide-based vesicles described in the previous chapter have been used for very few applications in the field of life science (as carriers for drug, genes, etc. or as bioreactors) and for the fabrication of organic/inorganic composite materials (encapsulation of inorganic nanoparticles). 

Investigating the fabrication and composition of semiconductor nanoparticles in polymer matrices has attracted the interest of many scientists. Inorganic/organic polymer nanocomposites, in particular, have attracted great interest due to their synergistic and hybrid properties derived from... 

Layered composite films can be directly prepared by alternate deposition or vacuum filtration of the mixed dispersions of both components. For instance, PANl/Prussian blue composite films have been fabricated using layer-by-layer assembly of the polycation PANI and a negatively ionized Prussian blue nanoparticle dispersion (DeLongchamp and Hammond, 2004). The resultant organic/inorganic nanocomposites exhibited good smoothness and a classical linear increase in film thickness with assembly steps. In...
