Microsensors for a variety of chemical compounds have
been developed
1
. Their application has enormously
enhanced the insight in the functioning of dense
microbial communities, as occuring in biofilms, sedi-
ments and microbial mats, in which metabolic pro-
cesses are typically confined to narrow zones of
0.1–10 mm wide. With microsensors high spatial
resolution studies are possible towards transport and
conversion
2
, however, the range of compounds that can
be measured with chemical microsensors is limited.
The here described microsensor for radioactivity allows
studies towards transport and binding of all com-
pounds that can be radioactively labelled.
