Summary

This handy reference is the first comprehensive book covering both fundamentals and recent developments in the field with an emphasis on nanotechnology. Written by a highly regarded author in the field, the book details state-of-the-art preparation, characterization and applications of thin films of organic molecules and biomaterials fabricated by wet processes and also highlights applications in nanotechnology The categories of films covered include monomolecular films (monolayers) both on a water surface and on a solid plate, Langmuir-Blodgett films (transferred multilayer films on a solid plate from a water surface), layer-by-layer films (adsorbed multilayer films on a solid support), and spontaneously assembled films in solution.

Author Biography

Dr. Katsuhiko Ariga is a director of the National Institute for Materials Science (NIMS). He received his B.Eng. M.Eng., and Ph.D. degrees from the Tokyo Institute of Technology (TIT). He was a research associate at TIT, worked as a postdoctoral fellow at the University of Texas at Austin, and then served as a group leader in the Supermolecules Project at JST. Thereafter, he worked as an associate professor in the Nara Institute of Science and Technology, and then entered the ERATO Nanospace Project, JST.
Ariga?s research interests are the fabrication of novel nanostructures based on molecular recognition and thin film technologies, including Langmuir-Blodgett, layer-by-layer, and mesoporous films, and has authored over 200 papers, 7 book chapters (with a further 14 in press) and 1 book. He has experience teaching students as an assistant professor at Tokyo Institute of Technology (1986-1992) and as an associate professor at Nara Institute of Science and Technology (1998-2001).
