Optical Chemical Sensors NATO Science Series A Series presenting the results of scientific meetings supported under the NATO Science Programme. The Series is publishedby IOS Press, Amsterdam, and Springerin conjunction with the NATO Public Diplomacy Division. Sub-Series I. Life and Behavioural Sciences IOS Press II. Mathematics,Physics and Chemistry Springer III.Computer and Systems Science IOS Press IV.Earth and Environmental Sciences Springer The NATO Science Series continues the series of books published formerly as the NATO ASI Series. The NATO Science Programme offers support for collaboration in civil science between scientists of countries of the Euro-Atlantic Partnership Council.The types of scientific meeting generally supported are “Advanced Study Institutes”and “Advanced Research Workshops”, and the NATO Science Series collects together the results of these meetings.The meetings are co-organized by scientists from , NATO countries and scientists from NATOs Partner countries – countries of the CIS and Central and Eastern Europe. Advanced Study Institutes are high-level tutorial courses offering in-depth study of latest advances in a field. Advanced Research Workshops are expert meetings aimed at critical assessment of a field, and identification of directions for future action. As a consequence of the restructuring of the NATO Science Programme in 1999, the NATO Science Series was re-organized to the four sub-series noted above.

This is evidenced by an annual growth in the number of international scientific conferences in which advances in the field of optical chemical sensors are reported. These conferences, are, however, focused on disseminating the latest scientific results rather than providing in-depth education in the field of optical chemical sensors. In addition, the topic of optical chemical sensors is only just beginning to find its way into the curricula of universities and colleges in Europe and in the US. Due to the prominence that optical sensors are assuming, it has become more and more important to establish a framework for discussion and interchange, in addition to traditional conferences, to aid research and education in this important field. In the summer of 2004, the NATO A.S.I. on the subject “Optical Chemical Sensors” was organised in Erice, Sicily. This NATO A.S.I. was the 40th Course of the International School of Quantum Electronics, under the auspices of the “Ettore Majorana Foundation and Center for Scientific Culture” and was directed by Dr. J. Homola of the Institute of Radio Engineering and Electronic (IREE) of the Academy of Sciences in Prague and by Dr. F.Baldini of the “Nello Carrara Institute of Applied Physics” (IFAC-CNR). It is also the fourth course in the framework of the ASCOS (Advanced Study Course on Optical Chemical Sensors) series, founded in 1999 by Prof. Otto Wolfbeis. This book presents the Proceedings of this advanced course providing a deep overview of both the fundamentals of optical chemical sensing and the applications of chemical sensors. The objective of the NATO A.S.I. was to bring together bright young (future) scientists, coming from all imaginable fields of expertise related to optical chemical sensors, to learn from selected researchers and from each other in an appropriate atmosphere. The course covered all the principal optical chemical sensor technologies and related fields and provided a platform to exchange ideas and experience. The objective was accomplished through teaching theory and basics on a level every participant could follow and then giving the participant an opportunity to apply the gained knowledge. The quality of the course was assured by the presence of 27 lecturers, key specialists for each topic, coming from 13 different countries (12 European countries plus the USA). An outstanding presence was assured by Prof. Charles Townes, one of the inventors of the laser, who was invited in occasion of the forty-year celebration of the Nobel Prize award in Physics for the discovery of the laser. His lecture during the ceremony was one of the most exciting moments ix
