75 Attend Fluorescence Spectroscopy Course

Photonics.com
Oct 2003
BERLIN, Oct. 31 -- A short course on "Principles and Applications of Time-Resolved Fluorescence Spectroscopy," sponsored by electro-optical instrumentation and systems developer PicoQuant GmbH, of Berlin, and the Center for Fluorescence & Spectroscopy of the University of Maryland Medical School, in Baltimore, was held last week in Berlin. Seventy-five attendees received an in-depth introduction to the principles of time-resolved fluorescence spectroscopy and its applications to the life sciences.


HANDS ON: Industry and research profressionals participate in a short course on fluorescence spectroscopy held recently in Berlin.
   The course was chaired by Joseph R. Lakowicz with Rainer Erdmann, managing director of PicoQuant GmbH. Course instructors were Joseph R. Lakowicz (Baltimore), Richard Thompson (Baltimore), Zygmunt Gryczynski (Baltimore), Rainer Erdmann, (Berlin), Michael Wahl (Berlin) and Matthias Patting (Berlin). Guest lecturers were Manfred Auer (Novartis AG, High Throughput Screening), Joerg Enderlein (FZ Juelich, Fluorescence Fluctuation Spectroscopy) Stefan Hell (MPI Goettingen, High-Resolution Microscopy) and Otto S. Wolfbeis (University of Regensburg; Markers, Probes and Labels).

The course covered the basics of steady state and time-resolved fluorescence spectroscopy and instrumentation, time- and frequency-domain measurements, anisotropy, solvent effects, quenching and Foerster energy transfer, as well as an introduction into data analysis. It also focused on theoretical and experimental details and advanced applications. In hands-on experimental sessions, participants worked with time-correlated single photon counting and phase fluorometry as well as microscopes, microplate readers and data analyis software. Evening social program stimulated discussion and networking.

Plans for an October 2004 course are underway, PicoQuant said.

GLOSSARY
electro-optics
1. The branch of physics that deals with the use of electrical energy to create or manipulate light waves, generally by changing the refractive index of a light-propagating material; 2. Collectively, the devices used to affect the intersection of electrical energy and light. Compare with optoelectronics.
fluorescence
The emission of light or other electromagnetic radiation of longer wavelengths by a substance as a result of the absorption of some other radiation of shorter wavelengths, provided the emission continues only as long as the stimulus producing it is maintained. In other words, fluorescence is the luminescence that persists for less than about 10-8 s after excitation.
