1. 

   Gold nanoparticles have great potential towards optical investigations in biological tissues which include imaging applications as well as therapeutic applications. However, the effectiveness of these techniques is greatly governed by the optical properties of the nanoparticles which are determined by its shape, size and composition and a variety of computational methods can be adopted to determine their optical efficiencies. A systematic study based on the finite-difference time-domain (FDTD) method was carried out to determine the trends in the optical properties of gold nanoparticles of varying sizes, shapes and compositions over a wavelength range of 380 nm-1064 nm. The finite difference ...
