This work has been supported by an Erwin Schroedinger
fellowship (Austrian Science Fund FWF), by the Swiss
National Science Foundation, by the Marie Curie Programme
of the European Union, and is currently supported within the
Werner Heisenberg Programme of Deutsche Forschungs-
gemeinschaft (German Research Foundation), the German
Academic Exchange Service, the Programme for promoting
young scientists (Friedrich - Schiller - Universität Jena), and
Fluka. This support is most gratefully acknowledged.
Commercially available reactands from Fluka:
For commercially available reactands (ETHT 4001, ETHT
4003, ETHT 4004, CR-514, and CR-546) have a look at the
homepage of Fluka and Aldrich. The chemically stable pH
indicator dye GJM-541 with colour changes from yellow to
purple, a pKa of 7.5, and a vinylsulfonyl group for covalent
immobilization will soon become available (find more details
in the List of Projects below).
ETHT 4001 is Fluka product number 18596, ETHT 4003 is
Fluka 28218, ETHT 4004 is Fluka 28222, CR-514 is Fluka
95647, and CR-546 is Fluka 08709.

New dyes for biotechnology and miniaturized optical
devices
Recent research focuses on reactands with methacrylate
groups for the preparation of molecularly-imprinted polymers
that recognize analytes even in aqueous medium.
Furthermore, miniaturized optical sensor modules based on
light emitting diodes and photodiodes attached to CMOS
chips are currently being developed for aqueous carbon
dioxide in cooperation with the original equipment
