Novel Electrochemical Sensors Based on L-Proline Assisted LDH for H₂O₂ Determination in Healthy and Diabetic Urine.

ABSTRACT: In this paper, a novel non-enzymatic modified glassy carbon (GC) sensor, of the (GC-Ag_paste)-catalytic proline-assisted LDH type, for H₂O₂ determination was fabricated, studied, characterized and employed to determine the hydrogen peroxide content in healthy and diabetic human urine. LDH (whose composition can be schematized as [Zn^IIAl^III (OH)₂]⁺ NO₃^-·nH₂O) is glued to glassy carbon by means of silver paste, while proline, which increases the catalytic properties of LDH, is used free in solution in the phosphate buffer. A voltametric survey was first conducted to ascertain the positive effect induced by the presence of proline, i.e., the increase of sensor sensitivity. Then a deep
