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.
Our approach lowers the size of nanosized plastics detectable via micro-Raman spectroscopy, exploiting the resonance Raman signal from blue-pigmented, highly abundant microplastics.
