Abstract

Background

Antibiotic identification with precision is crucial. Vanadium selenide (V₃Se₄) was synthesized and later encapsulated onto the beta-cyclodextrin/reduced graphene oxide nanosheets (β-CDN/rGONs) to achieve efficient electrochemical sensing of moxifloxacin hydrochloride (MFH) in water and biological samples. Due to their unique characteristics as composite structures, transition metal chalcogenides (TMDs) with carbon composite (V₃Se₄/ β-CDN/rGONs) were produced.

Methods

The structural and functional analysis by X-ray diffraction, Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy revealed the crystalline purity and the successful formation of the composite material. Transmission electron microscopy were done to study the morphological properties of the material. The morphological analysis revealed spherical structure of the (V₃Se₄) material and wrinkled sheets of β-CDN/rGONs.

Significant Findings

The V₃Se₄/β-CDN/rGONs modified glassy carbon electrode (GCE) has been subjected to electrochemical sensing. A sensor for detecting MFH antibiotics employing cyclic voltammetry (CV) and differential pulse voltammetry (DPV) was developed. The DPV investigation has a low limit of detection (LOD) 15.2 nM, a wide linear range about 0.02 μM to 873.3 μM, and with the sensitivity of 1.87 μA μM^-1 cm². The sensor's performance demonstrated good analyte recovery rates for real sample measurement in biological and environmental aquatic samples. The findings indicated that the sensor performs well at detecting MFH and has the potential for future applications.

硒化钒封装β-环糊精/rGO 纳米片：一种有效的水生环境和生物样品中抗生素的电化学检测方法

背景精确鉴定抗生素至关重要。研究人员合成了硒化钒 (V3Se4)，随后将其封装在β-环糊精/还原氧化石墨烯纳米片（β-CDN/rGONs）上，实现了对水和生物样品中盐酸莫西沙星（MFH）的高效电化学传感。方法通过 X 射线衍射、傅立叶变换红外光谱和 X 射线光电子能谱进行结构和功能分析，结果表明该复合材料的结晶纯度很高，并已成功形成。透射电子显微镜研究了材料的形态特性。形态分析表明 (V3Se4) 材料为球形结构，β-CDN/rGONs 为皱褶片状结构。利用循环伏安法（CV）和差分脉冲伏安法（DPV）开发了一种检测 MFH 抗生素的传感器。DPV 调查的检测限（LOD）为 15.2 nM，线性范围宽，约为 0.02 μM 至 873.3 μM，灵敏度为 1.87 μA μM-1 cm2。该传感器在生物和环境水样的实际样品测量中表现出良好的分析回收率。研究结果表明，该传感器在检测 MFH 方面表现良好，具有未来应用的潜力。
