汞被认为是水生资源中最危险的污染物;它对环境和人类健康产生许多不利影响。迄今为止,在使用各种纳米材料比色检测汞离子方面取得了重大进展。电纺纳米纤维表现出几个有益的特点,包括很大的表面积,多孔性质,和易于功能化;因此,提供了几个机会,以增强的灵敏度和选择性封装各种传感应用的功能材料,和一个快速的反应。在这次审查中,通过利用两种最重要的方法设计的基于电纺纳米纤维的传感平台的几个例子,即,提供了用于检测汞离子的直接结合和表面装饰。我们相信这些例子为电纺纳米纤维在汞离子比色传感方面的潜在用途和进展提供了充分的证据。此外,综述的摘要集中在提供对设计基于静电纺纳米纤维的未来方向的见解,金属离子比色传感器的实际应用。
Mercury is considered the most hazardous pollutant of aquatic resources; it exerts numerous adverse effects on environmental and human health. To date, significant progress has been made in employing a variety of nanomaterials for the colorimetric detection of mercury ions. Electrospun nanofibers exhibit several beneficial features, including a large surface area, porous nature, and easy functionalization; thus, providing several opportunities to encapsulate a variety of functional materials for sensing applications with enhanced sensitivity and selectivity, and a fast response. In this
review, several examples of electrospun nanofiber-based sensing platforms devised by utilizing the two foremost approaches, namely, direct incorporation and surface decoration envisioned for detection of mercury ions are provided. We believe these examples provide sufficient evidence for the potential use and progress of electrospun nanofibers toward colorimetric sensing of mercury ions. Furthermore, the summary of the
review is focused on providing an insight into the future directions of designing electrospun nanofiber-based, metal ion colorimetric sensors for practical applications.
