Current as a function of time for (a) 2D Ag/rGO sensor and (c) 3D Ag/rGO sensor with and without dopamine by introducing a variety of interfering neurotransmitters such as ascorbic acid (AA), histamine (His), uric acid (UA), epinephrine (EP) and 3,4-Dihydroxyphenylacetic acid (DOPAC) at a potential of āˆ’0.1ā€‰V. Current responses are plotted against interferents for 2D Ag/rGO (b) and 3D Ag/rGO (d). Error bars in (b) and (d) are the SD of measurements over at least nā€‰=ā€‰3 biologically independent experiments. Error bars, meanā€‰Ā±ā€‰SD.
