Electrochemical detec tion of Gl ucose on a Ni/Cr L DH mod ified elect rode

In this paper a Ni/Cr layered double hydroxide (LD H) was first synthesized and was us ed to modify a GC electrode. The LDH/GC m odified electrode can be directly use d as the wo rking electr ode of a no nenzymatic glucose sensor. The el ectrochemical response of the electrodes was characterized in solution. Cyclic v oltammetry (CV) technique was employed. The LDH/GC electrod e could be used for el ectrochemi cal nonenzymatic gluco se low det ection limit, good reproducibility, long-term stab ility, fast cu rrent respon se, and low interference .In recent years, layered doubl e hydroxide s (LDH), al so known as anionic or hydrotalcite-like clays, have growing interest for using i n the wide fields owing to their attracted desirable prope rties, which include good biocompatibility[۱], intense adsorbability [۲], high catalytic activity , low cost , and high chemical sta bility [۳].
