Immobilization of HRP Enzyme on Layered Double Hydroxides for Biosensor Application
Figure 1
(a) Cyclic voltammetry measurement in PBS buffer of bare gold electrode and gold electrode with LDH, respectively. (b) Nyquist diagram ( versus ) of impedance measurement corresponding to the gold electrode without and with LDH layer. (c) Atomic force microscopy photo of gold surface treated with LDH. It shows a homogenous surface with roughness below 1 nm.
