In addition to SEM, AFM and XRD analysis, the presented sensor was studied with respect to its response to Fe(CN)(6)(4-/3-) and characterized by CV and EIS techniques. Under the optimum conditions, TiO2-Ag/PPy/GCE showed a good linear relationship over a concentration range from 4.10 x 10(-8) to 3.06 x 10(-6) M with a detection limit of 2 x 10(-6) M. The availability of the sensor was examined by analysis of TA in food samples.en10.1016/j.synthmet.2018.10.006info:eu-repo/semantics/closedAccessTyramineElectrochemical sensorNanocompositeFood sampleArticle24696100Q1WOS:000453491800010Q2
