The self-organization of nanopartides is a powerful tool for the constmction of highly ordered colloidal crystals, biologically active substrates, and optical and electronic devices. Most studies of nano/micropartide assembly have focused on metal or silica partides due to their ideal properties for electronics and optics. One example is the self-assembly of polymeric partides by Wang et whereby the sdf-assembly of PS nanopartides...

The formation of nanopattemed functional surfaces is a recent topic in nanotechnology. As is widely known, diblock copolymers, which consist of two different types of polymer chains cormected by a chemical bond, have a wide variety of microphase separation structures, such as spheres, cylinders, and lamellae, on the nanoscale, and are expected to be new functional materials with nanostructures. Further modification of the nanostructures is also useful for obtaining new functional materials. In addition, utilization of nanopartides of an organic dye is also a topic of interest in nanotechnology. 

Traditional methods for fabricating nano-scaled arrays are usually based on lithographic techniques. Alternative new approaches rely on the use of self-organizing templates. Due to their intrinsic ability to adopt complex and flexible conformations, proteins have been used to control the size and shape, and also to form ordered two-dimensional arrays of nanopartides. The following examples focus on the use of helical protein templates, such as gelatin and collagen, and protein cages such as ferritin-based molecules. 

Other materials have also been used to produce modified nanopartide films to detect organic vapors. Murray and coworkers [26] showed that the modification of nanopartides with a carboxylate ligand, which can complex with a metal ion, Cu +,... 

Just as in the case of gold nanopartides, appropriate choice of the capping agent for modification of the surface of nanopartides may be used to accomplish the phase transfer of aqueous silver nanopartides. Wang, Efrima and Regev have shown that silver nanopartides can be phase transferred from water to organic solvents by binding the nanopartides to sodium oleate present in cyclohexane/...

Independent of the dimensionahty, the organization of metal nanopartides seemed to be linked with the existence of a protecting ligand shell that enveloped the particles surfaces. The most important reason for this condition was seen as a necessity to grow the arrangements from solution. 

This form of nanopartides organization is related to a method which is based on the wetting instabilities of monomolecular layers when transferred onto solid... 

Composite materials exhibit excellent performance, which can be widely used in aerospace, defense, transportation, sports, and other fields. Nanocomposites are one of the most attractive parts of the composite materials. Due to the fast development in recent years, nanocomposites are widely used by the developed countries for manufacturing new materials. The research on nanocomposites indudes organic-inorganic composites, nanopolymer matrix composites, and inorganic-inorganic composites. In this chapter, combined with our research experience, we mainly introduce the nanopolymer matrix composites to the readers. The synthesis and modification of nanopartides and preparation, characterization, and applications of nanopolymer matrix composites are mainly discussed.

The focus of nanoscience is gradually shifting from the synthesis and characterization of individual nanopartides (NPs) to the organization of larger nanostmaures. Current interest in this research field is driven by the ability to exploit coupled...
