Resumo
The poly(dimethylamino methacrylate) (PDMAEMA) brush-modified indium tin oxide (ITO) electrode was used to test the switch properties of interfacial activity caused by bioelectrochemical signals. The swelling of the polymer brushes increased when the medium's pH changed from alkaline to acid after glucose was added to the system. A pH change generated in situ by means of biocatalytic reactions enabled bioelectrocatalytic interface's reversible activation. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
