Blue micro-/nanoplastics abundance in the environment: a double threat as a Trojan horse for a plastic-Cu-phthalocyanine pigment and an opportunity for nanoplastic detection <i>via</i> micro-Raman spectroscopy

Summary

Researchers exploited the resonance Raman signal of copper-phthalocyanine blue pigment in abundant environmental blue microplastics to enable micro-Raman spectroscopic detection of nanoplastics below conventional size limits, simultaneously identifying pigmented microplastics as a dual environmental threat and detection opportunity.
