Chemical sensing using optics is under extensive research all over the
world and many optical chemical sensors are finding increasing
application in industry, environmental monitoring, medicine, biomedicine
and chemical analysis. 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 th the
40 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).
