Abstract:
We investigate modifications of a spontaneous emission rate near the surface of the hemoglobin-like dielectric structure in the long-wavelength limit. We demonstrate that notwithstanding the small size of the dielectric structure, an influence of its shape cannot be neglected. Even for moderate dielectric contrasts one can expect having significant and detectable enhancement or suppression of the spontaneous emission rate near the surface of the biological macromolecule.
