Challenges and Recent Analytical Advances in Micro/Nanoplastic Detection
AI summary Read the abstract
This review covers the challenges scientists face in detecting and measuring micro- and nanoplastics in the environment, especially for particles smaller than one micrometer. Current analytical methods have significant limitations for identifying nanoplastics due to their extremely small size and diverse chemical compositions. Improving detection technology is essential for accurately assessing how much microplastic contamination exists in water, food, and human tissues.
Despite growing ecological concerns, studies on microplastics and nanoplastics are still in their initial stages owing to technical hurdles in analytical techniques, especially for nanoplastics. We provide an overview of the general attributes of micro/nanoplastics in natural environments and analytical techniques commonly used for their analysis. After demonstrating the analytical challenges associated with the identification of nanoplastics due to their distinctive characteristics, we discuss recent technological advancements for detecting nanoplastics.
