Nanoparticles

The integration of top-down lithographic techniques with synthetic organic and inorganic technologies is a key challenge for the development of effective nanosca1e devices. In terms of assembly, nanoparticles provide an excellent tool for bridging the gap between the resolution of electron beam lithography (-60 nm) and the molecular level. Nanoparticles possess an array of unique properties associated with their core materials, including distinctive magnetic, photonic and electronic behavior. This behavior can be controlled and applied through monolayer functionalization and assembly strategies, making nanoparticles both scaffolds and building blocks for nanotechnology. The diverse structures and properties of nanoparticles makes them useful tools for both fundamental studies and pragmatic applications in a range of disciplines. This volume is intended to provide an integrated overview of the synthesis and assembly of nanoparticles, and their applications in chemistry, biology, and materials science. The first three chapters focus on the creation and intrinsic properties of nanoparticles, covering some of the myriad core materials and shapes that have been created. The remaining chapters of the book discuss the assembly of nanoparticles, and applications of both discrete particles and particle assemblies in a wide range of fields, including device and sensor fabrication, catalysis, biology, and nanosca1e electronic and magnetic systems.

Klappentext

The diverse structures and properties of nanoparticles make them useful tools for both fundamental studies and pragmatic applications in a range of disciplines. This volume is intended to explore this diversity. The first section covers on formation of nanoparticles, and assembly of these systems into structured systems. The second section focuses on both the fundamental physical properties of nanoparticles and pragmatic applications of these systems in the areas of device and materials fabrication. The book will approach the subject from a chemical standpoint, in contrast to most books which are oriented towards materials science or physics. It will also appeal to materials scientists and physicists who are becoming aware of the contributions that chemists can make here.
