“…Such nanostructure composed by monodisperse colloids on the mesoscale of 50-500 nm has important applications in optical information processing, such as photonic crystal [1][2][3][4], catalyst support [5,6], and size-selected membranes [7,8]. Besides, order arrays of metal clusters with quantum dot size have drawn considerable interests due to their potential applications in optical, electronic, and biosensing devices [9][10][11][12][13][14].…”

Arrays of metal nanoparticles in an organic matrix have attracted a lot of interest due to their diverse electronic and optoelectronic properties. By varying parameters such as the nanoparticle material, the matrix material, the nanoparticle size, and the interparticle distance, the electronic behavior of the nanoparticle array can be substantially tuned and controlled. For strong tunnel coupling between adjacent nanoparticles, the assembly exhibits conductance properties similar to the bulk properties of the nanoparticle material. When the coupling between the nanoparticles is reduced, a metal insulator transition is observed in the overall assembly. Recent work demonstrates that nanoparticle arrays can be further utilized to incorporate single molecules, such that the nanoparticles act as electronic contacts to the molecules. Furthermore, via the excitation of the surface plasmon polaritons, the nanoparticles can be optically excited and electronically read out.

“…A number of other groups have now used this method to form multilayer films of gold particles [117] , polymer-capped platinum colloidal particles [118] , bulky balls [119] . The Brust synthesis procedure [7] wherein gold nanoparticles are synthesized and capped with alkanethiols in a nonpolar organic phase continues to be the most popular means of obtaining hydrophobic gold nanoparticles that are readily dispersible in different nonpolar/weakly polar organic solvents [120] .…”

To manipulate the size of noble metal particles on a nanometer scale are priority subjects in the field of nanotechnology. So far various approaches have been developed to synthesize noble metal nanoparticles in controlled sizes and dimensions. Among them the colloidal systems become broadly used. These systems can be made up of several very different reactants and solvents: a continuous medium water or alkane, surfactant and precursor(s). In some systems the formation of (sub) nanoparticles is based on the supersaturation of solution by reactants. The existence of the microenvironments gives them a particular ability to modulate the chemical reactivity of the reactants due to their compartmentalization in different microenvironments. The size and shape of noble metal nanoparticles follow the feed composition of reactants in the precursor solution, the reaction conditions and concentration and type of reactants. Surface modification and functionalization is expected to increase the stability of nanoparticles and organize them to the assembly of higher order array conjugates. Various soft and hard templates can be applied to produce noble metal nanoparticles in different shaped nanoreactors. Monodisperse gold nano crystals can grow inside soft templates and the cavities of hard templates by the reduction of metal ions trapped in the cavities. The interesting optical properties of noble metal nanoparticles and their (bio)conjugates results from the strong absorption in the visible spectrum region, so called the surface plasmon absorption. Some noble metal nanoparticles have been studied for their antimicrobial potential and have proven to be antibacterial and antiviral agents.
