Nickel Nanoparticle-Modified Electrode for the Electrochemical Sensory Detection of Penicillin G in Bovine Milk Samples

<div>CVs of bare SPCE (a) and NiNPs/SPCE (c) in 1.0 mM K<sub>3</sub>Fe(CN)<sub>6</sub> and 0.1 M KCl. (b, d) corresponds to the respective plots of peak currents (<i>μ</i>A) against the square root of scan rate (V/s)<sup>1/2</sup> (0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, and 0.1 V/s).</div>
