eng	Electrochemical Properties of Novel Screen-Printed Sensors with Bare and Modified Boron-Doped Diamond Working Electrode	Screen-printed sensors (SPE) represents a simple solution for miniaturizing of electrochemical analysis. The possibility of cheap production of a large number of sensors of any shape and parameters of individual electrodes, which allows their use as disposable sensors, is the main advantage of SPE. It is also possible to perform analyzes in very small sample volumes (50-100 µl). Very good repeatability of their preparation is an essential condition for disposable sensors3-5. The choice of a suitable working electrode is crucial with regard to the properties of SPE. The combination of the mentioned advantages of printed sensors with exceptional electrochemical properties of boron-doped diamond electrode (BDDE)6-8 represents a promising tool for POCT9,10. Another way to increase the sensitivity or selectivity of electrochemical methods is to modify the surface of commonly used working electrodes11, e.g., with nanoparticles of metals and their oxides, carbon nanomaterials, organic molecules or polymers, or biomolecules such as various enzymes or DNA. The subject of this work is the study of electrochemical properties and possibilities of application of a new laboratory-prepared printed sensor with chemically deposited BDDE modified with metal nanoparticles.
