Toward a hydrogen peroxide sensor for exhaled breath analysis
In this contribution a chip-integrated amperometric sensor for the detection of H2O2 in exhaled breath condensate (EBC) is reported. The electrode chip is characterized, and detection of H2O2 in an aqueous phase is shown by means of cyclic voltammetry (CV) and amperometry. Variation of conditions such as the composition of the supporting electrolyte largely influences the obtained electrochemic...
متن کاملQuantitative analysis of 8-isoprostane and hydrogen peroxide in exhaled breath condensate.
Exhaled breath condensate (EBC) provides a noninvasive means of sampling the lower respiratory tract. Collection of EBC might be useful in the assessment of airway oxidative stress in smokers. The aim of this study was to determine 8-isoprostane and hydrogen peroxide levels in EBC, and, in addition, to investigate the reproducibility of these measurements. EBC samples were collected from 12 hea...
متن کاملHydrogen peroxide in exhaled breath condensate in patients with asthma: a promising biomarker?
BACKGROUND The measurement of hydrogen peroxide (H(2)O(2)) in exhaled breath condensate (EBC) has been proposed as a noninvasive way of monitoring airway inflammation. However, results from individual studies on EBC H(2)O(2) evaluation of asthma are conflicting. The purpose of this study was to explore whether EBC H(2)O(2) is elevated in people with asthma and whether it reflects disease severi...
متن کاملHydrogen peroxide in exhaled breath condensate in asthmatic children during acute exacerbation and after treatment.
BACKGROUND In asthmatics, the concentration of hydrogen peroxide (H(2)O(2)) in exhaled breath condensate (EBC) has been found to be increased and to be related to airway inflammation. OBJECTIVE The aim of this study was to determine whether in children with acute exacerbation, exhaled H(2)O(2) levels could be influenced by treatment and linked to airway obstruction. METHODS Twenty-two asthm...
متن کاملFractionated exhaled breath condensate collection shows high hydrogen peroxide release in the airways.
BACKGROUND Exhaled breath condensate (EBC) allows noninvasive monitoring of inflammation in the lung. Activation of inflammatory cells results in an increased production of reactive oxygen species, leading to the formation of hydrogen peroxide (H(2)O(2)). In addition, cigarette smoking causes an influx of inflammatory cells, and higher levels of H(2)O(2) have been found in EBC of smokers. Howev...
