In this paper, a highly sensitive photo-electrochemical sensor based on a screen printed carbon electrode SPE was developed for nitrite detection. The sensor was functionalized with titanium oxide nanoparticles having excellent photocatalytic properties. The functionalization of the working electrode was investigated by performing scanning electron microscopy imaging and energy-dispersive-X-ray (EDX). Both methods confirmed the successful modification of the electrodes. In addition, an optimization of pH value of the phosphate buffered saline (PBS) solution was performed...
