Supercell-enhanced multimodal plasmonic sensor for high-fidelity antigen detection via refractive index modulation
Abstract In this study, we investigate a multispectral plasmonic refractive index sensor based on a ring resonator supercell array for the detection of carcinoembryonic antigen (CEA), prostate-specific antigen (PSA), and hemoglobin (Hb). The sensor exhibits three resonance modes within the 1000–3000...
