Development of the Electrode for the Particle Sampling Using Negative Dielectrophoresis by Additive Synthesis Sine Wave
AI summary Read the abstract
Researchers developed an electrode system combining negative dielectrophoresis with additive synthesis sine wave driving signals for concentrating and quantifying ocean microplastics, using optical attenuation measurement to enable quantitative assessment of particles smaller than 5 mm.
ABSTRACT Currently, no technology has been established to measure the amount of ocean microplastics (MP) less than 5 mm. As a basic study of the quantitative evaluation, the authors proposed measurement method using the attenuation of transmitted light for the amount of microplastic that concentrated by dielectrophoresis. In this study, we report effective collection method of microplastics by combining an electrode structure that generate negative dielectrophoresis and a driving method using additive Synthesis sine wave.

Machine learning-based dual-modality rapid in-flow microplastic sizing using combined dielectrophoretic and optical features
AI summary Read the abstract
Scientists have developed a fast new device that combines two detection methods, light scattering and an electrical technique, to more accurately measure the size of individual microplastic particles as they flow through a tiny channel. This matters because knowing the exact size of microplastics is key to understanding how they might affect our bodies, since smaller particles can potentially penetrate tissues more easily; better sizing tools like this could help researchers more reliably study microplastic exposure and its health risks.
Electrochemical Detection of Microplastics in Water Using Ultramicroelectrodes
AI summary Read the abstract
Researchers developed a new electrochemical method for detecting microplastics in water using ultramicroelectrodes. The technique works by monitoring changes in electrical current when microplastic particles collide with and adsorb onto the electrode surface, and the size distributions obtained closely matched independent measurements, demonstrating its potential as a practical detection tool.
