A Linear sweep voltammograms of AzA/silver nanoclusters modified electrode in the absence (a) and presence (b) of 2.4 × 10–5 M EP in 0.1 M PBS. [Stirring rate: 300 rpm]. B Amperometric response of the AzA/silver nanoclusters modified electrode for the successive additions of 4.14 × 10–5 M EP in 0.1 M PBS. [Stirring rate: 300 rpm; Operating potential: + 0.3 V]. Inset: Calibration plot of amperometric current response of AzA/silver nanoclusters modified electrode vs [EP]. C Current response of the AzA/silver nanoclusters modified electrode towards 2.4 × 10–5 M EP determination for a period of 45 days. (Inset: current response of the modified electrode vs time in min)
