a Representative CVs of 5 µM 5-HT measured at each electrode. b Au-CNT (2 µL) membrane electrode sensitivity to a range of 5-HT: 500 nM–100 µM using an accumulation time of 10 min. The inset shows a Langmuir curve fit (n = 2 cycles per two electrodes). c Au-CNT (12.5 µL) membrane electrode sensitivity to a range of 5-HT: 10 nM–1 µM using an accumulation time of 2 h. A line fit was applied to the data (n = 2 cycles per two electrodes)
