Abstract

Silica‐based nanomaterials have attracted huge attention for maximizing their safety and efficacy due to their nontoxicity, chemical and thermal stability, size tunability, and versatile functionality. Nanosilica with ZnO or carbon in a composite has excellent usage as an electrochemical sensor. Recent technological progression in nanotechnology and nanoscience has seen a number of applications of zinc oxide (ZnO) nanomaterials ranging from electronics, and sensing to environmental, and biomedical applications because of its various applications, multifunction, high specific surface area, stability, biocompatibility, nontoxicity, electrochemical activities, and so on. Carbon also has various advantageous properties like renewability, low ohmic resistance, and very stable response due to which carbon paste electrodes have attracted attention in the fabrication of electrochemical sensors. Electrochemical sensors are inexpensive, portable, and have excellent ability in detecting water contaminants, pesticides, disinfectants, pathogens, and different molecules. Artificial dyes are usually mixed with vegetable sauces, drinks, and other food items, which can cause cancer in human body. Voltametric methods with electrochemical sensors can be used to detect them in food samples. In this review, the present applications of ZnO and carbon nanomaterial‐based chemical sensors are meticulously studied to detect water contaminants and food dyes where nanosilica plays an important role as a sensor modifier.

二氧化硅、碳和氧化锌纳米材料在制造用于检测水污染物和食品染料的电化学传感器中的作用
硅基纳米材料因其无毒性、化学和热稳定性、尺寸可调性和多功能性,在最大限度地提高安全性和功效方面引起了广泛关注。纳米二氧化硅与氧化锌或碳的复合材料可用作电化学传感器。由于氧化锌(ZnO)具有多种用途、多功能、高比表面积、稳定性、生物相容性、无毒性、电化学活性等特点,近年来纳米技术和纳米科学的发展见证了氧化锌(ZnO)纳米材料在电子、传感、环境和生物医学等领域的大量应用。碳还具有可再生性、低欧姆电阻和非常稳定的响应等各种优势特性,因此碳浆电极在电化学传感器的制造中备受关注。电化学传感器价格低廉、便于携带,在检测水污染物、杀虫剂、消毒剂、病原体和不同分子方面具有出色的能力。人造染料通常混入蔬菜调味汁、饮料和其他食品中,会在人体内致癌。使用电化学传感器的伏安法可以检测食品样品中的人工染料。在这篇综述中,详细研究了目前基于氧化锌和碳纳米材料的化学传感器在检测水污染物和食品染料方面的应用,其中纳米二氧化硅作为传感器改性剂发挥了重要作用。
