  I wanted to know how to add an aditional coating on a sphere and what are the things that I need to take care of while simulating a SERS based biosensor

  Lumerical uses "mesh order" to distinguish different geometries/materials. Therefore, you can add a coating sphere with radius R1 on the base sphere R2, where R1>R2, and choose the mesh order of the base sphere higher than R1, or choose R1's mesh order lower than R2. Please refer Understanding mesh order for overlapping objects
  Please refer this example: Surface-enhanced Raman scattering I wrote a few tips there.
