Nanostructure Synthesis in Aqueous Media
Alexander Pyatenko

In this chapter the main experimental methods used for synthesis of metal nanostractures in aqueous colloidal form are considered. For the convenience, consideration was made separately for noble metals and magnetic metals, even the most of methods are generally common for both groups. While the chemical reduction of metal ions still remains the main method for such synthesis, laser ablation in water solutions as well as combinations of these two methods became more and more popular, and can bring more promising results in nearest future.

Surfactant Based Synthesis of Metal Nanosystems
Jian Zhang, Hanying Zhao

Design of consistant and facile methods for the synthesis of silver nanoparticles is a significant forward direction in the field of application of materials science, nanotechnology and medicine. A number of methods have been suggested in the literature for the synthesis of non-agglomerated nanoparticles. These include natural and synthetic polymers, biological macromolecules, latex particles, mesoporous inorganic materials, dendrimers, microgels or hydrogels, colloidal systems and others. In this chapter, we review the latest development of various surfactant based synthesis of metal nanoparticles with a few illustrations how the stability, morphology and complexity of nanosystems differs with current methodologies.

Microemulsion Mediated Synthesis of Nanoparticles
Deepa Sarkar and Kartic. C. Khilar

The water in oil microemulsion or reverse micelle has been used in the past two decades for synthesis of many different types of nanoparticles. The nano meter sized aqueous cores of the reverse micelle provides an appropriate stabilized environment for the production of nanoparticles of fairly uniform size, through chemical reactions occurring in the core and it also acts as steric stabilizers to inhibit the aggregation of nanoparticles formed. The water in oil microemulsion has been used to synthesize different types of core nano particles (metals, and semiconductors) as well as core-shell/ composite nanoparticles. This article describes the preparation techniques, and the various techniques used to characterize these core and core-shell nanoparticles as well as insights in to the effects of various process parameters on the terminal particle size. A brief review of our modeling work based on stochastic population balance is also presented, which can be used to describe the formation of both core and core-shell nanoparticles. In addition, we also present a brief review of the work on the synthesis of anisotropic nanostructures like nanorods and nanowires by templating against surfactant micelles and reverse micelles. Some findings of our work on addressing the engineering issues such as possibility of reuse of surfactant and organic phases are also included in this article.

Synthesis of Metal Nanostructures by Photoreduction
Bo Hu, Hong-Yan Shi, Shu-Hong Yu

Metal nanostructures with the size range of 1-100 nm, featuring unique physical and chemical properties that arise from their quantum size effects and high surface areas, have been the focus of recent scientific research. Among a variety of synthetic methods, the photoreduction method represents a promising strategy for controlled synthesis of metal nanostructures with different sizes, shapes and composition. In this review, the latest development on synthesis of metal nanostructures by UV radiation, γ-ray radiation, and laser radiation methods will be overviewed with specific examples to illustrate how to generate metal nanostructures with unusual structural specialty and complexity. The perspectives on combination of this method with solution processing and interfacial reactions are given.

Self-Assembly of Nanostructures
Mustafa Çulha

This chapter is mainly focused on current novel approaches that have been made to synthesize metal nanoparticles with predetermined shape, size, and fair stability using self assembly process. It has also demonstrated that influence of various inorganic, organic compounds, polymer, and biological molecules on the nanostructures of particles.

Rational Synthesis Approaches to Metal Nanoparticles and Polymer Metal Nanocomposites
K. Samba Sivudu, Y. Murali Mohan and K. Mohana Raju

The scientific and industrial need for novel composite materials and nanoparticles has opened new paths and led to significant advances in the field of nanocomposites. A number of nanosystems can be designed based on their unique physico-chemical structures for direct biomedical applications. This review is focused on the most novel strategies and trends to design metal nanoparticles including thermal decomposition, chemical reduction and green methods. These methods can be applied to fabricate polymer metal nanocomposites into different forms: core –shell, hollow core- shell nanoparticle system, metal nanoparticles in hydrogel matrix and layer by layer assembly systems. The resulted new class of materials found fascinating interest in antimicrobial, drug delivery and in catalysis.
