The Effect of Multilayer Gold Nanoparticles on the Electrochemical Response of Ammonium Ion Biosensor Based on Alanine Dehydrogenase Enzyme
Figure 3
Cyclic voltammograms of a gold electrode modified with immobilised 2BME/AlaDH enzyme and coated with 3-layer AuNPs in the absence (a) and presence (b) of 1.6 mM ion. The measurement was conducted in the presence of 0.1 mM pyruvate and 0.2 mM NADH at pH 7 with a scan rate of 100 mV/s.
