Summary:
Through the development and application of a lateral nanoflow assay, we reveal that a common nanoparticle system – which is simultaneously a commercial product, model nanoplastic, and unofficial standard – is hiding surprising optical properties in plain sight. Our study achieves a new combination of quality and efficiency in colloidal metrology and has important implications for nanoparticle manufacturing and nanoplastic analysis.
