Editing Plasmons (section)

=== Applications of Plasmons ===
Plasmons have a wide range of applications, particularly in the fields of optics and materials science:
* '''Surface Plasmon Resonance (SPR)''': SPR is a technique used for sensing molecular interactions. It exploits the sensitivity of surface plasmons to changes in the refractive index near a metal surface, making it useful in biological and chemical sensing.
* '''Nanophotonics''': In nanophotonics, plasmons are used to confine light to subwavelength scales, enabling the development of highly miniaturized optical devices such as waveguides, sensors, and filters.
* '''Plasmonic Solar Cells''': Plasmonic materials are incorporated into solar cells to enhance light absorption, thereby improving the efficiency of photovoltaic devices.
