Selectivity and specificity of the aptasensor.
(A) Square wave voltammograms of the selectivity experiments performed by incubating the R4–6 aptamer-based sensor with (a) buffer alone, (b) 700 C. parvum oocysts, and (c) 1,000 G. duodenalis cysts, and (d) 5.1 mg/mL HSA. (B) Plot of ΔI and (C) ΔE vs. the tested target.
