Abstract

This paper presents a flexible printed sensor for the accurate detection of uric acid (UA) by a simple chemical route synthesis. The sensitive nanomaterial (N-rGO) was prepared from the dual interaction of 1,4-xylenediamine (XDA) and Graphene oxide (GO) by covalent and π-π stacking interaction. N-rGO was printed on a flexible polyvinyl chloride (PVC) substrate and analyzed in 0.1 M PBS, pH 7.4 electrolyte for different concentrations of UA. The sensor exhibited a wide segmented linear range of 3-40 × 10-5 M and 1-8 x 10-3 M with a sensitivity of 0.733 mAmM-1 and 0.0277 mAmM-1 respectively. The 0.0077% standard deviation from 30 consecutive measurements suggests that the sensor exhibits excellent reproducibility. Thus, the presented sensor is an alternative to currently available commercial bulky UA sensors.
