- Abstract
- ― Submicron plastics have gained significant attention within the ecosystem due to their notable hazards. For better understanding of nanoplastics, establishing an effective analytical platform is crucial. However, the ultra-minute concentration and extremely small scales of nanoplastics present considerable technical obstacles for detection, including diffusion and detection limitations. In this study, we obtained real-time Raman signals from underwater nanoplastics with ultralow concentrations by employing electric tweezing. This approach enables the active collection of nanoplastics from remote areas. Moreover, the synergistic combination with plasmonic nanorods achieves the highest on-site detection performance reported thus far.
