Fabrication and characterization of plasmonic membrane. Schematic representation of the plasmonic fidget spinner (P-FS) used for the isolation and digital detection of bacteria through SERS mechanism. A urine sample is introduced to capture and enrich bacteria via centrifugal force from spinning the P-FS device. The enriched bacteria on the plasmonic filter was processed for enhanced Raman signal detection using laser-induced SERS. Unique bacterial fingerprints are captured and displayed in digital Raman spectroscopy profiles, differentiating positive (“1”) and negative (“0”) detections, with intensity represented in heatmaps.
