- •
GR and p-AHNSA nanostructured composite film based screen printed carbon sensor (SPCs) has been fabricated.
- •
The nanostructured composite film exhibited high electrocatalytical activity.
- •
High selectivity for 5-HT and DA and lower detection limits were observed.
- •
The proposed method was successfully applied to detect 5-HT in patient plasma sample.
- •
The analytical applicability of sensor was demonstrated in biological fluids.
