(A) Square Wave Voltammograms of the RVFV aptasensor before and after incubation with varied RVFV nucleoprotein concentrations prepared in Binding Buffer. The measurements were conducted in a 5 mM [Fe (CN)6] 4−/3− solution within PBS buffer at pH 7.4 The SWV scan potential range was from 0.4 to -0.4 V with a step potential of 5 mV, an amplitude of 20 mV, and a frequency of 25 Hz. (B) Calibration curve for the RVFV aptasensor, depicting a plot of the logarithmically transformed concentrations of RVFV protein against the aptasensor response ((i0-i)/ i0%). The error bars represent standard deviations derived from triplicate measurements.
