Fig. 10From: A new strategy for the determination of the antidiabetics alogliptin, saxagliptin and vildagliptin using all-solid state potentiometric sensorsChronopotentiogram of DBP based electrode with different internal solid contacts: Screen printed carbon, Au nanostructure thin film/Pt and Pt/Pt wire. The measurements were performed in 1 × 10–3 M ALO+. The applied current is + 1 nA and − 1 nA for 1 minBack to article page
