Figure 7

(a) Schematic illustration of DA release by Ca2+ and K+. The Ca2+ ion channels with K+ are more active than one without K+. (b) KCl concentration-dependent DA concentration produced by cell exocytosis (the error bars were calculated as standard deviation, n = 5). (c) Real-time responses of CPNT2-aptasensor to exogeneous DA samples released at various KCl concentrations. (d) Selectivity of CPNT2-aptasensor to exogeneous DA sample in mixtures.
