Research Overview:
We use fast scan cyclic voltammetry (FSCV) to monitor changes in
dopamine levels because background subtracted cyclic voltammograms can
be generated, and allow for positive identification of species that
contribute to changes in current. The electrodes are made with a single
carbon fiber sealed in a tapered capillary tube (Figure 1). The carbon
fibers
are around 7 microns in diameter, and have properties that are ideal
for detecting the electroactive neurotransmitter dopamine (DA). The
background subtracted cyclic voltammogram in this plot is
characteristic of dopamine (Figure 3). For more information on our
current research please visit the links on the right.
