Description |
The flow injection analysis (FIA) of monosodiuml-glutamate (MSG) was performed electrochemically using a biosensor
based on screen-printed electrodes containing carbon nanotubes (CNT). The sensor was fabricated by simply
adsorbing glutamate oxidase (GlutOx) on the electrode surface. The resulting device displayed excellent electroanalytical
properties toward the determination ofl-glutamate in a wide linear range (0.01–10mM) with low detection
limit (10 nM, S/N
!3), fast response time ( 5 s), and good operational and long-term stability. The CNT-modified
screen-printed electrodes have a potential to be of general interest for easy preparation of electrochemical sensors
and biosensors relevant for biomedical applications.
