Advances and prospects of carbon dots for microplastic analysis
AI summary Read the abstract
This review assessed the potential of carbon dots, luminescent nanomaterials derived from carbon sources, as tools for microplastic detection and analysis in food and environmental samples, offering advantages in sensitivity and selectivity over conventional methods. The authors identify carbon dot-based sensing as a promising direction for filling the gap in standardized microplastic analytical methods.
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.
