The sensitive layer was prepared by electropolymerization of phenol on gold electrodes in the presence of the template (phenylalanine). The insulating properties of the polymer layer were studied by electrochemical impedance spectroscopy. Electrical leakages through the polymer layer were suppressed by deposition of a self-assembled monolayer of mercaptophenol before polymerization and of alkanethiol after polymerization. At the final stage of sensor preparation, the template was removed. The multilayer system obtained displayed a decrease in electrical capacitance on addition of phenylalanine. Only a low response was observed toward other amino acids and phenol.}, language = {en} } @misc{MirskyHirschPanasyuketal., author = {Mirsky, Vladimir M. and Hirsch, Thomas and Panasyuk, Tatiana L. and Piletsky, Sergey A. and Wolfbeis, Otto S.}, title = {Two- and three-dimensional artificial chemoreceptors: molecular spreader-bar vs. molecular imprinting}, series = {Medical and Biological Engineering and Computing}, volume = {37}, journal = {Medical and Biological Engineering and Computing}, number = {suppl.2}, issn = {0140-0118}, pages = {344 -- 345}, language = {en} } @misc{MirskyHirschPiletskyetal., author = {Mirsky, Vladimir M. and Hirsch, Thomas and Piletsky, Sergey A. and Wolfbeis, Otto S.}, title = {A spreader-bar approach to molecular architecture: formation of stable artificial chemoreceptors}, series = {Angewandte Chemie International Edition}, volume = {38}, journal = {Angewandte Chemie International Edition}, number = {8}, issn = {1521-3773}, doi = {10.1002/(SICI)1521-3773(19990419)38:8<1108::AID-ANIE1108>3.0.CO;2-C}, pages = {1108 -- 1110}, abstract = {The destructive influence of lateral diffusion on nanostructured monolayers can be prevented by using the spreader-bar technique.
