Background parameters of the medium. ${\mu }_{\alpha ,660}^c$ and ${\mu }_{s,660}^{\prime }$ were measured by the method used in Ref.[39]. ${\mu }_{\alpha ,694}^c$ and ${\mu }_{s,694}^{\prime }$ were extracted by fitting the experimental data of the homogeneous Cy5.5 solution to the theoretical data based on the measured values of ${\mu }_{\alpha ,660}^c$ and ${\mu }_{s,660}^{\prime }$. ε ₆₆₀ and ε ₆₉₄ were approximated from the maximum molar excitation coefficient of Cy5.5 in water (0.25 cm⁻¹μM⁻¹) at 675 nm. Units of the absorption and scattering coefficients are cm⁻¹.
