Simplified Detection of Serotonin by FET-Based Sensor
35
Fig. 3 Variation of I d with V gs before and after antibody functionalization and after serotonin
(antigen) capture
Fig. 4 Variation of sensitivity with different serotonin concentrations in buffer and serum
This phenomenon has been justified due to the lower number of target biomolecules
are being captured for the equal quantity of pipetted solution.
4 Conclusion
This present study describes the development of fast, label-free, economical, ZnO
nanorod FET-based biosensor for serotonin detection in serum. The fabrication of the
sensor was characterized by FESEM and XRD. The selection of FET-based sensor for
