ClearChallenges and Recent Analytical Advances in Micro/Nanoplastic Detection
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.

Critical gaps in nanoplastics research and their connection to risk assessment
This paper identifies critical knowledge gaps in nanoplastics research and explains why they matter for assessing health and environmental risks. Nanoplastics are harder to detect and measure than larger microplastics, meaning current pollution estimates likely undercount total plastic contamination. The authors call for better detection methods and standardized research approaches to understand the true scope of nanoplastic exposure.

Challenges and Advances in Analytical Techniques to Detect Micro- and Nanoplastics
This research review summarizes the current methods scientists use to detect and study microplastics and nanoplastics - tiny plastic particles that can get into our environment, food, and bodies. The authors explain that identifying these extremely small plastic pieces is very challenging and requires advanced laboratory techniques to understand what types of plastics they are and how much is present. Better detection methods are important because we need to understand how much plastic pollution we're exposed to and its potential effects on human health.
Nanoplastics: From Separations to Analysis—Challenges and Limitations
This review examines the challenges of analyzing nanoplastics in environmental samples, from sample preparation to identification.

The missing small microplastics: easily generated from weathered plastic pieces in labs but hardly detected in natural environments
This paper reports that small microplastics and nanoplastics are easily generated in the laboratory from weathered plastic pieces but are rarely detected in field samples, attributing the discrepancy to the lack of suitable environmental detection methods rather than their absence in nature.
