In Situ Detection and Imaging of Microplastics in Water Using Ultrasound and Photo Acoustic Technology
Summary
This study explored the use of ultrasound and photoacoustic technology for in situ detection and imaging of microplastics in water, addressing the need for field-deployable, non-invasive monitoring tools. The combined acoustic approach demonstrated the ability to detect and localize microplastics in water samples, offering a promising complement to laboratory-based spectroscopic methods.
Microplastics in ocean has become one of the major threats to marine life and associated ecosystem and this will eventually impact our future generation. Therefore, detection of microplastics in ocean is essential to assess and control the pollution. Although, there are established methods for detecting microplastic, none are compatible for in situ application. In this paper, we evaluate the potential of two promising techniques, ultrasound and photo acoustic technologies for in situ detection of microplastic.
