In this study, we have succeeded in detecting the neurotransmitters at nM level using multi-wall carbon nanotube (MWCNT) Bamboo and Hollow electrodes. CNT electrodes were created with mineral oil and graphite powder in order to press the electrode surface. In cyclic voltammetry measurements, dopamine was detected at 1 nM level using MWCNT Bamboo electrodes and serotonin at 1 nM level using MWCNT Hollow electrode. Moreover, in chronoamperometry measurement, dose-response relationships from 10 nM to 100 µM were observed in dopamine and serotonin. These results suggest that MWCNT bamboo and Hollow electrodes have a potential for the real-time measurement of neurotransmitters from living neurons.
