Circular economy projects that measure the impacts of increasing circularity.
We are developing nanoplastic arrays as innovative reference materials for microspectroscopy calibrations. Our multifunctional standards will enable calibrations of instrument responses and nanoplastic structure–property relationships.
Methods to quantify nano- and microplastics (NMPs) in the environment are being developed in laboratories across the world, but they are not standardized and often result in data that cannot be compared across studies. NIST researchers are developing optimal methods along the entire workflow, including extraction, purification, and analysis of count, size, shape, polymer identity, and mass of NMPs. As part of this effort, the NIST SPHERE is being used to accelerate the aging of plastic to generate weathered plastic particles to support MNP measurement advances.
