Description We present here a mathematical formulation determining the enhancement factors of Raman scattered light from molecules adsorbed on to multiply coated ellipsoidal particles. We use this formulation to present enhancement of Raman scattering from molecules, such as pyridine and CV from nanoparticles of gold and silver as well as their core-shell structures with magnetic metal cobalt. The nanoparticles of these metals are widely used in biomedical applications. We also present results for the cases when the nanoparticle is covered with a monolayer of Raman active molecules and dispersed randomly in a medium. Our results can be of importance in medical technology.
