Nanoplastics prepared with uniformly distributed metal-tags: a novel approach to quantify size distribution and particle number concentration of polydisperse nanoplastics by single particle ICP-MS
Summary
Researchers developed a new method for creating nanoplastic test particles with embedded metal tags, allowing scientists to precisely measure the size and number of nanoplastics using single-particle mass spectrometry. The particles have realistic irregular shapes and varied sizes, unlike the uniform spheres typically used in lab studies. This tool will help researchers more accurately study how nanoplastics behave in environmental and health experiments.

Researchers evaluated a suite of techniques for measuring the size, shape, and chemical makeup of nanoplastics — plastic particles smaller than 1 micrometer — and found that no single method works for all sample types, especially when particles vary in size or clump together. Combining multiple complementary techniques is essential for reliable nanoplastic characterization, particularly in complex environmental or biological samples.
