Plasmonic Detection of Microplastics and Microorganisms Using a Circular-Nanorod-Coupled MIM Sensor

AI summary Read the abstract

Researchers designed a compact plasmonic sensor based on a silver metal-insulator-metal waveguide coupled to an octagonal cavity embedded with circular nanorods, achieving dual resonance sensitivities of 1,321 and 2,198 nm/RIU that enable optical detection of microplastics and aquatic microorganisms through refractive index shifts.
