Abstract :

H ere, as-prepared iron oxide nanoparticle have prepared by a wet-chemical process using reducing agents in alkaline phase. The nanoparticles were characterized using UV/vis., FT-IR, and Raman spectroscopy, powder X-ray diffraction, and field- emission scanning electron microscopy. They were deposited on a glassy carbon electrode (surface area, 0.0316 cm2) to give a sensor with a fast response towards Aprepitant drug in buffer phase. The sensor also exhibits good sensitivity and long-term stability as well as enhanced electrochemical responses. The calibration plot is linear over the large APPT concentration ranges. The sensitivity is ~2.5316�0.5 μAcm -2 mM -1 , and the detection limit is 0.38�0.02 nM (at a Signal-to-Noise-Ratio of 3) in short response time (10 sec). This method could also be employed for the detection of APPT drug in quality control of formulation using a reliable I-V technique.
