A device for detecting a biomarker for inflammation in a respiratory system includes a sample collection and/or holding area to receive an exhaled breath condensate (EBC) sample obtained from a respiratory system; an electrode system coupled to the sample collection area, the electrode system including reduced graphene oxide (rGO); and circuitry coupled to the electrode system. The circuitry is configured to apply a voltage to the EBC sample in the sample collection area via the electrode system and to measure a current via the electrode system in response to the voltage applied, in order to determine a concentration of nitrite in the EBC sample based on the current measured. The concentration of nitrite is a biomarker for inflammation in the respiratory system.
