A new method of capturing nanoplastics has been developed, which could help us better understand the environmental impacts of this emerging pollutant. Nanoplastics are tiny, plastic particles that are smaller than 100 nm and are a growing environmental problem. These particles are so small that they can pass through wastewater treatment plants and end up in our oceans and other water sources. In order to measure the impact of nanoplastics, we need to develop methods to accurately capture and analyze them.

Now, researchers from the University of Portsmouth have developed a technique for capturing nanoplastics and determining their size and shape. The method uses a combination of optical tweezers, lasers, and microscopy to capture and analyze individual nanoplastics particles. This information is then used to assess their environmental impact. The technique is also able to accurately measure the size and shape of nanoplastics particles, which are important factors in understanding their impact on the environment.
