Optical Bio-diagnostics
Murray, George1

Abstract-
This talk will attempt to introduce some of the key concepts to be explored
by this symposium. "Optical Bio-diagnostics"
encompasses a broad overview of the means by which optical methods can
be used to obtain relevant information about biological systems through
processes that selectively monitor relevant chemicals. One aspect of
the symposium is concerned with the application of optical sensing strategies
to measure molecules of biological significance. Of particular interest
are approaches to molecular recognition through biological or biomimetic
means. The use of selective chemical receptors equipped with chromophores
for sensitive detection has become a means for achieving both high selectivity
and high sensitivity, unattainable by other means. Another key component
of bio-diagnostics is minimally-invasive imaging. The combination of
selective chemical recognition and imaging will be explored.
