New screen-printed sensors with chemically deposited boron doped diamond electrode – electrochemical properties and application

Abstract

The subject of this work was the investigation of electrochemical properties and application possibilities of new screen-printed sensors (SPE) with chemically deposited boron doped diamond electrode (BDDE). Using conventional redox markers ([Fe(CN)6]4−/3− and [Ru(NH3)6]2+/3+), these sensors were tested in comparison with bulk BDDE in a standard arrangement and commercially available SPEs based on the evaluation of the parameters of the obtained cyclic voltammograms. At the same time, the new sensors were applied in the determination of a number of bioactive substances important from the point of view of environmental protection or human health (e.g., drugs and pesticides).
