Abstract:
Microplastics have become the world\'s most emerging pollutants today due to the ubiquitous use of plastics in everyday life and their ability to migrate from micro to nanoscale to every corner of the natural world, leading to ecological imbalances and global catastrophes. However, a standardized method for separating and analyzing microplastics from actual food or environmental samples has not been established. Therefore, it is necessary to develop a simple, fast, cost-effective, and accurate method that can accurately measure the degree of contamination of microplastics. As one of these methods, fluorometry has been proposed as a cost-effective method to detect, quantify and differentiate individual plastic particles. Therefore, this review discussed the technique for analyzing microplastics using fluorescent carbon dots (CDs). This review provided an overview of the impact of microplastics and the feasibility of using CDs to detect and analyze microplastics. In particular, this review will discuss novel microplastic analysis methods using CD and future application studies. The method using CDs will overcome the limitations of current microplastic analysis technology and may become a new method for detecting and analyzing microplastics.
摘要:
微塑料已成为当今世界上最新兴的污染物,由于塑料在日常生活中的无处不在,以及它们能够从微米到纳米尺度迁移到自然界的每个角落,导致生态失衡和全球灾难。然而,尚未建立从实际食品或环境样品中分离和分析微塑料的标准化方法。因此,有必要开发一个简单的,快,成本效益高,和准确的方法,可以准确测量微塑料的污染程度。作为这些方法之一,荧光测定法已被提出作为一种经济有效的检测方法,量化和区分单个塑料颗粒。因此,这篇综述讨论了使用荧光碳点(CD)分析微塑料的技术。这篇综述概述了微塑料的影响以及使用CD检测和分析微塑料的可行性。特别是,这篇综述将讨论使用CD的新型微塑料分析方法和未来的应用研究。使用CD的方法将克服当前微塑料分析技术的局限性,并可能成为检测和分析微塑料的新方法。
