eng	Electrochemical properties of screen-printed sensors with boron-doped diamond working electrode for point-of-care testing	In this work, the newly prepared SP/BDDEs were characterized by scanning electron microscopy (SEM) and Raman spectroscopy. Their electrochemical properties were investigated using cyclic voltammetry of commonly used inner sphere ([Fe(CN)6]4−/3−) and outer sphere ([Ru(NH3)6]2+/3+) redox markers. The applicability of new sensors was tested by analysis of several bioactive substances important in the field of environmental protection or human health. The tested SP/BDDEs were found to provide very good electrochemical properties and suitability for electroanalysis. It was confirmed that the intra-electrode repeatability of the recorded current signals is very good, indicating excellent sensor stability. Moreover, excellent inter-electrode repeatability was proven also in the case of signals recorded by individual SP/BDDE tested, which allows their use as disposable sensors.
