eng Laser-modified screen-printed sensors based on boron-doped diamond electrode: electro-chemical properties and potential application in electroanalysis The subject of this work was the study of the laser-modified screen-printed sensors based on boron-doped diamond electrode on their electrochemical properties and applicability. The influence of the number of times of laser treatment on the surface of the working electrode was investigated. The working electrode surface was characterized using Raman spectroscopy, digital holographic and scanning electron microscopies. Using conventional redox markers ([Fe(CN)6]4−/3−, [Ru(NH3)6]2+/3+, [IrCl6]3−/2− and dopamine), the electrochemical properties of these modified sensors were compared based on the evaluation of the parameters of the obtained cyclic voltammograms. The effect of laser treatment of the working electrode on the analysis of organic acids (ascorbic, barbituric and folic) was investigated.
