Plasmonic and Surface Plasmon Research

Plasmonics studies how light interacts with the free electrons in metal and nanoscale structures, producing tightly confined electromagnetic waves called surface plasmons that can concentrate optical energy far below the diffraction limit of conventional optics. In biomedical engineering, this control over light at the nanoscale enables highly sensitive biosensors capable of detecting single molecules, as well as targeted photothermal therapies and imaging tools that operate within living tissue. Researchers are actively exploring how newer materials — including graphene and engineered metamaterials — can extend these capabilities into the terahertz spectrum and improve the tunability and efficiency of nanoantennas and optical modulators. Open challenges include managing energy losses in plasmonic systems, translating laboratory devices into clinically viable platforms, and understanding how complex biological environments alter plasmonic resonance behavior.
