Abstract
In this paper for the first time, due to the importance of simultaneous administration of sertraline (SRT) and buspirone (BPH), a sensitive electrochemical nanosensor was fabricated and used for simultaneous measurement of them. Firstly, fMW@TiO2@MoS2-Sm2S3 was synthesized and characterized by different techniques. The performance of fMW@TiO2@MoS2-Sm2S3/GCE nanocomposite was investigated for simultaneous quantifications of SRT and BPH using different electrochemical methods. Response surface methodology (RSM) indicated that pH 7.0 for phosphate buffer solutions (PBS), scan rate of 0.08 V s-1, accumulation potential of 0.4 V and accumulation time of 125 s in CHA get maximum anodic currents. The anodic peak current densities of SRT and BPH drugs were improved excellently on the surface of fMW@TiO2@MoS2-Sm2S3/GCE compared to bare GCE. With the DPV method, the linear response 1.53–38.46, 38.46–74.07 µM and 1.11–29.12, 29.12–90.90 µM were obtained for SRT and BPH, respectively. Also, the detection limit of 0.50 µM and 0.36 µM were acquired for SRT and BPH, respectively. The catalytic rate constants were calculated to be 3.63 × 107 and 2.80 × 107 cm3 mol-1 s-1 for SRT and BPH, respectively. The practical application of the fMW@TiO2@MoS2-Sm2S3 for measurements of the SRT and BPH in human plasma and tablets showed good recovery percentage.
期刊介绍:
The aim of the journal is to provide a respectful outlet for ''sound science'' papers in all research areas on surfaces and interfaces. We define sound science papers as papers that describe new and well-executed research, but that do not necessarily provide brand new insights or are merely a description of research results.
Surfaces and Interfaces publishes research papers in all fields of surface science which may not always find the right home on first submission to our Elsevier sister journals (Applied Surface, Surface and Coatings Technology, Thin Solid Films)
