LASER stands for light intensification by stimulated emission of radiation. We all know that light is an electromagnetic wave. Each wave has its own glare and color, and vibrates at a convinced angle, called polarization. This concept also applies to laser light but it is more similar than any other light source. Every part of the beam consumes almost exact same direction and so the beam will deviate very little. With a good laser an object at a distance of 1 km can be irradiated with a dot about 60 mm in radius. As it is so similar, it can be focused to very small diameters where absorption of light energy becomes so high that you can drill, cut, or turn with the ray. It is also conceivable to illuminate and inspect very tiny details with the lasers, thus it is utilized in surgical applications and CD players as also. It can also be made very monochromic, thus only one light wavelength is present. This is not the instance with the normal light sources. White light consumes all colors in the spectrum, but even a colored light, such as a red LED has a repeated interval of red wavelengths.

Surface-enhanced Raman scattering (SERS) or Surface-enhanced Raman spectroscopy is a surface sensitive technique which enhances Raman scattering by the molecules adsorbed on the rough metal surfaces or by the nanostructures such as plasmatic magnetic silica nanotubes and the enhancement factor can be as much as 1010 to 1011, which means the method may detect single molecules. The mechanism of enhancement effect of SERS is a matter of discussion of issues in the literature. There are two basic theories and their mechanisms differ significantly, distinguishing them experimentally has not been forthright. The electromagnetic theory recommends the excitation of sectarian surface Plasmon’s, and then the chemical theory recommends the composition of charge transfer complexes. The chemical theory applies only for the species that have formed a chemical bond with surface. So it cannot clarify the observed signal development in all the cases, whereas electromagnetic theory can put on even in those cases where the specimen is physically absorbed only to the surface. It has been shown lately that SERS improvement can occur even when the excited molecule is relatively far apart from the surface which swarms metallic nanoparticles enabling surface Plasmon phenomena.
