Problem Statement: In the current study the effort was being made to investigate the effect of LASER light on the shape and geometries of Gold Nanoparticles. Light is an important parameter that plays significant role in the formation of nanoparticles; in this study LASER lights of selected wavelengths and colors have been used for the exposure of Gold Nanoparticles. The possibilities to manipulate the geometries of Gold Nanoparticles by altering the colors and wavelengths of LASER have been studied with reference to their efficacy against Culex quinquefasciatus. Approach: In the experimental setup four black boxes are used with no exposure to light sources. Three LASER with selected wavelengths and colors were fixed in the boxes at a specific angle, and then the nanoparticle solution was allowed to react. The micrographs of the Gold nanoparticles have been evaluated through the Transmission Electron Microscope (TEM). Results: The TEM images have shown formation of different shapes of nanoparticles due to exposure in different colors and wavelengths of LASER. Thus it explains that the wavelength and colour of the light plays a decisive role in the formation of the shapes and geometries of the nanoparticles.
