We propose a model based on to understand fluorescense resonance energy tranfer (FRET) between molecules (donor) and gold nanopartical (acceptor). Mechanism of transferring energy from the electronically excited donors to acceptors is described in the spirit of a virtual photon exchange. Additionally, the dipole-dipole interaction is supposed to dominate other forces in the electronic coupling. Our approach associated with experimental data shows that (1) conventional FRET is observed for small gold nanopartical, and (2) FRET is found to be primarily due to surface energy transfer as increasing size of particales. This finding is in good agreement withprevious studies and would pave the way for experimental investigation.
