In the presence of phenol as a trapping agent, glucose as a substrate, and pyrroloquinoline quinone-containing glucose dehydrogenase (PQQ-GDH) as a catalyst, the current signal for the trapping adducts (catechol and hydroquinone) produced by the hydroxylation of phenol could be amplified and detected sensitively. The limit of detection (S/N = 3) for catechol was 8 nM. The trapping efficiency of phenol was also estimated., Article, ANALYTICAL SCIENCES. 27(11):1065-1067 (2011)}, pages = {1065--1067}, title = {Sensitive Electrochemical Detection of the Hydroxyl Radical Using Enzyme-catalyzed Redox Cycling}, volume = {27}, year = {2011} }
