Subsecond adsorption and desorption of dopamine at carbon-fiber microelectrodes.
High-repetition fast-scan cyclic voltammetry and chronoamperometry were used to quantify and characterize the kinetics of dopamine and dopamine-o-quinone adsorption and desorption at carbon-fiber microelectrodes. A flow injection analysis system was used for the precise introduction and removal of a bolus of electroactive substance on a sub-second time scale to the disk-shaped surface of a micr...
متن کاملPedot/go Carbon Fiber Microelectrodes for Dopamine Sensing
INTRODUCTION Dopamine (DA) sensing has become an important emerging technology due to the regulatory role of DA signaling in neurological diseases such as schizophrenia, addiction and Parkinson’s. However, due to its low concentration in the CNS relative to coexisting species such as ascorbic acid (AA), DA can be difficult to detect accurately. When using traditional electrodes, the recorded ox...
متن کاملPlatinized aligned carbon nanotube-sheathed carbon fiber microelectrodes for in vivo amperometric monitoring of oxygen.
The abnormal level of O2 could disturb various neurochemical processes and even induce neural injury and brain dysfunction. In order to assess critical roles of O2 in the neurochemical processes, it is essential to perform in vivo monitoring of the dynamic changes of O2. In this study, we develop a new electrochemical method for selectively monitoring O2 in vivo, using platinized vertically ali...
متن کاملHigh Temporal Resolution Measurements of Dopamine with Carbon Nanotube Yarn Microelectrodes
Fast-scan cyclic voltammetry (FSCV) can detect small changes in dopamine concentration; however, measurements are typically limited to scan repetition frequencies of 10 Hz. Dopamine oxidation at carbon-fiber microelectrodes (CFMEs) is dependent on dopamine adsorption, and increasing the frequency of FSCV scan repetitions decreases the oxidation current, because the time for adsorption is decrea...
متن کاملCarbon Fiber-based Microelectrodes and Microbiosensors
The chemically relatively inert carbon fiber (CF) has outstanding mechanical and electrical properties and provides an excellent base electrode for electrophysiological, electrochemical and biosensor applications on a micrometer or perhaps even on a submicrometer scale. CF microelectrodes have been used to record neuronal action potentials (spikes) since 1979 (Armstrong-James & Millar, 1979). T...
