Note: Advances in nanoscale self-assembly techniques have made it possible to design and fabricate nanostructured surfaces with specific optical properties. Materials of this type are of great interest to the biotechnology and optoelectronics industries. 

Nanoplasmonic devices are engineered by placing nanoscale nanoplastic materials in a regular array on a flat surface. These self-assembled spheres act as a template for the growth of gold and other materials. Once the nanoplastic material is gone, the structure is the result of an array of nanopores - a nanoplasmonic surface - with attractive nanoscale and macroscopic interactions with light. Nanostructured metal substrates act as antennas to attach incident light to nanoparticles or small molecules, allowing them to be examined at very low concentrations. Nanoplasmonics, the unique interaction of light with nanoscale metallic materials, can achieve unparalleled sensitivity.




Nanoscale plasmonic the process of interaction between electromagnetic waves and electrons conductivity in metals at the nano-scale is expressed ,  for analysis due to rapid loss of energy of electrons passing through metal and concluded that energy spend swarm swing species The free electrons become metal and it is called plasmon. The reason for this naming was the similarity of these electron oscillations with the oscillations of the particles in the plasma environment. The term polariton is used to oscillate metal-bound electrons when paired with incident beam phonons. The name polariton was used for quasi-particles that were half matter and half photons, which is a coupled state between an elementary excitation beam photon and metal conduction electrons.With technology approaching the aggregation of optoelectronic circuits, fabrication problems and phenomena that helped prevent further compression of the structure led to the use of plasmonic structures and plasmonic waves. These nanostructures are composed of metal and dielectric, the dimensions of which are below the excitation wavelength (the wavelength of the beam that excites the plasmonic waves).


Conclusion : 

Advances in nanoscale self-assembly techniques have made it possible to design and fabricate nanostructured surfaces with specific optical properties. Materials of this type are of great interest to the biotechnology and optoelectronics industries.
