In vitro calibration of glutamate-sensitive microelectrodes.
Sensitivity (pA/μM) | LOD (nM) | R2 | Selectivity |
---|---|---|---|
10.52 ± 0.95 | 571.32 ± 1116.19 | 0.991 ± 0.002 | 97.20 ± 12.78 |
Data are based on 30 glutamate-sensitive microelectrodes (mean ± SEM); LOD, limit of detection; R2 depicts the linearity of the response of the microelectrode to increasing concentrations of glutamate; Selectivity refers to the ratio of the electrode response to glutamate relative to ascorbic acid.
