Graphene's limited visible plasmonic resonance is addressed with a V2CTx MXene–AgNP composite for sensitive anti-cancer drug SERS detection.
A PCB-based sample carrier isolates chambers for dielectrophoretic liquid handling and vibrational spectroscopy, reducing cross-contamination.
Wide-field photothermal detection and computational tomography address slow, low-depth label-free imaging while recovering mid-IR molecular fingerprints.
