Increase of the photocurrent as a function of ATP concentration in the functionalized LoC system with PHEMA-aptamer for 10 and 20 min incubation time, varying [Ru(phen)2(dppz)]2+ concentration: (a) 0.5 µM (y = 1.68 + 1.22 log(x), and y = 1.71 + 1.28 log(x), for 10 and 20 min incubation, respectively); (b) 1 µM (y = 1.71 + 1.16 log(x) and y = 1.60 + 1.19 log(x), for 10 and 20 min incubation, respectively); and (c) 2 µM (y = 1.31+ 1.18 log(x) and y = 1.13 + 1.30 log(x), for 10 and 20 min incubation time, respectively).
