This report shows that a nonlinear Raman approach, namely surface-enhanced Raman spectroscopy (SERS) based on the use of nanotextured plasmonic 3D substrates, can be considered as a brute-force method to minimise these problems and bring the spectroscopic recognition of micro-polymers to a qualitatively new level. By utilising a novel gold-coated nanoconical carbon plasmonic substrate and a powerful discriminative principal component analysis method, 100% identification accuracy is obtained from a mixture of common polymer micro-fragments sized between 5–100 µm.
B.03 Paper at an international scientific conference
The invited talk at the conference about the design, optimisation and use of high-performing metal coated plasmonic nanostructures that reveal a possibility of trace analyte Raman detection. Excellent sensitivity and decent substrate robustness were achieved by proper material selection its nanotexturization and plasmonic functionalisation.
