(A) Spectra of colloidal solutions of PANI/GOx composite nanoparticles synthesized at various solution pH values and (B) the influence of polymerization bulk solution pH on the absorbance at λ_max = 440 nm. (The composition of polymerization solution: 0.05 mol L⁻¹ of glucose, 0.50 mol L⁻¹ of aniline and 0.75 mg mL⁻¹ of glucose oxidase at pH 1.0–10; 48 h lasting polymerization was performed. Optical absorbance was registered in 0.05 mol L⁻¹ SA buffer, pH 6.0).
