Together with Univ. Prof. Dr. Max E. Lippitsch, head of the group, I have been engaged in research in the field of modern optics and time-resolved spectroscopy for more than 20 years. The work extends from ultrafast spectroscopy of biomolecules to technological applications of luminescence decay time techniques.
Research activities can be grouped in the following major categories:
(1) Basic research on
fluorescence decay time measurements on novel fluorescent materials
behavior of fluorescent molecules in membranes
basic investigations of mechanisms for ion sensing
Development of lifetime sensor instrumentation
low-cost devices for field measurements
autonomous monitoring systems
lifetime imaging devices
Advantages of luminescence lifetime sensors
Optical sensors based on luminescence lifetime
are a promising alternative because of the following features:
proven long-term performance
no analyte conssumption
negligible impact on the environment
no interference from electrical and magnetical fields
and environmental monitoring:
To achieve a progress in operational forecasting of the seas and oceans, there is a strong need for a world-wide system of ocean-monitoring stations. None of the standard electrochemical sensors, however, fulfils the criteria for long-term autonomous monitoring. The properties of luminescence lifetime sensors provide the possibility for the use in unattended monitoring systems, floating buoys, unmanned platforms, and voluntary observing ships.
Medical diagnostics is facing a number of new challenges: Better
medical sevices for increasing number of people, intensive care,
homecare, emergency medicine. Optical sensors may provide a multitude
of versatile diagnostic instruments that can be manufactures rather
inexpensively and used conveniently.
