Experiments
with screen printed graphite electrodes as conductivity transducers are
also in progress in the frame of a community project [Brite Euram BE (95)
1745] which involves molecularly imprinted polymers (methacrylate) deposited
on the electrode surface for atrazine analytical determination in environmental
samples. In the slide the deposition of a molecular imprinted film (atrazine
as target molecule) on the graphite electrodes after treatment with 3-(trimethoxysilyl)propylmethacrylate
is shown as thickness of the thin polymer layer on the thick film electrode.
