Plasmonic structures are engineered materials that support surface plasmons, which are coherent oscillations of electrons at the interface between a metal and a dielectric. These structures enhance electromagnetic fields at the nanoscale, making them highly useful for various applications including sensing, imaging, and catalysis in nanoscale chemical reactions and synthesis. By manipulating light at these tiny scales, plasmonic structures can significantly improve the efficiency of chemical processes and enable new pathways for synthesis.
congrats on reading the definition of plasmonic structures. now let's actually learn it.
