Summary

This study demonstrated the detection sensitivity of stimulated Raman scattering microscopy for identifying microplastic beads within fish tissue, characterizing how signal-to-noise ratio varies with particle size. The technique provided chemical contrast to distinguish different plastic types within biological tissue without destructive sample preparation.

We demonstrate the detection sensitivity of microplastic beads within fish tissue using stimulated Raman scattering (SRS) microscopy. The intrinsically provided chemical contrast distinguishes different types of plastic compounds within fish tissue. We study the size-dependent signal-to-noise ratio of the microplastic beads and determine a lower boundary for the detectable size. Our findings demonstrate how SRS microscopy can serve as a complementary modality to conventional Raman scattering imaging in order to detect and identify microplastic particles in fish tissue.
