Multilayer membranes via layer-by-layer deposition of ascorbate oxidase and Au nanoparticles on the Pt electrode for reduction of oxidation current derived from ascorbate
A glass plate was alternately immersed in an Au colloid (10 nm φ) and an ascorbate oxidase (AO x ) solution (0.1 mg/mL, pH 6.8). Absorbance at 530 nm originating from the Au particles increased with the increasing number of depositions. The AO x activity of the plate also increased as the plate was...
