Summary

Researchers used small-angle neutron scattering (SANS) and ultra-SANS (USANS) with neutron contrast matching to directly measure aggregation and size changes of nanoplastics in the presence of vermiculite soil microparticles suspended in water. The study provided quantitative structural insights into nanoplastic-soil particle interactions that are difficult to obtain with conventional light scattering techniques.

Small-angle neutron scattering (SANS) and ultra-SANS (USANS), with neutron contrast matching techniques, measured aggregation and size reduction for nanoplastics in the presence of vermiculite, an artificial soil, suspended in water.
