<b>Professor Watt Webb</b>, Cornell University<br>
<i>Spectroscopies as Biophysical Tools from MilliHz to ExaHz<br>
</i>The spectroscopy of fluctuations of optical signals from biological
systems provides us with powerful probes of the dynamics of life. The
single molecule sensitivity of fluorescence can be utilized for
correlation spectroscopy to characterize chemical kinetics of single
enzymes, and for nonlinear dynamical imaging to observe their spatial
correlations, which has revealed 2-d critical phenomena that appear to
account for heterogeneity in cell membranes. Nonlinear spectroscopies of
<i>in vivo</i> tissue fluorescence and harmonic generation are now
revealing the onset of cancer, mapping neuronal communication and
metabolism, and more to be reported.<br><br>
