Combined sensing of Glut and DA at a constant potential of 0.7 V (vs. Ag/AgCl). The microprobe was tested with AA (250 μM), Glut (20 μM, 40 μM), DA (5 μM, 10 μM), H2O2 (10 μM), DA (60 μM), and Glut (140 μM), sequentially. The first two injections resulting in Glut concentrations of 20 μM and 40 μM are denoted as Glut′ and the latter injection at higher Glut concentration giving 140 μM is denoted as Glut″. Similarly, the first two injections resulting in DA concentrations of 5 μM and 10 μM are denoted as DA′ and the latter injection at higher DA concentration giving 60 μM is denoted as DA″.
