研究目的
To address the emerging environmental concern of nanoplastic pollution by developing a method for the analysis of nanoplastic particles in the size range from 200 nm to 5 μm, overcoming the limitations of current analytical approaches.
研究成果
The developed optical trap-based flow cell for the hyphenation of FFF with RM enables the analysis of nanoplastic particles in the size range of 200 nm to 5 μm with concentrations around 1 mg/L (109 L-1). This technique shows potential for application in nanoplastic analysis and other fields of nanomaterials, providing size information and chemical characterization simultaneously.
研究不足
The technique is limited to particles in the size range of 200 nm to 5 μm and requires particle concentrations around 1 mg/L (109 L-1). The sensitivity is dependent on the focal volume and is subject to fluctuations caused by particle material properties, making quantification solely via the Raman flow cell challenging.
