Abstract

This work reports nitrite detection in EBC samples using reduced graphene oxide as the sensing material. Nitrite content in EBC can be a potential biomarker for inflammation in the respiratory system. The performance of the sensor was characterized in standard nitrite solutions using cyclic voltammetry and square wave voltammetry and then was applied to patient EBC samples. The sensor has a sensitivity of 0.21 µA µM-1 cm-2 in the range of 20-100 µM and 0.1 µA µM-1 cm-2 in 100-1000 µM nitrite concentration with a low detection limit of 830 nM in EBC matrix.
