Abstract
Angle-resolved light scattering spectroscopy of biological cells is investigated in the visible wavelength range. A unified Mie and fractal model is shown to provide an accurate global agreement with light scattering spectra from 1.1° to 165° scattering angles. It is found that light scattering in forward directions is dominated by Mie scattering by the bare cell and nucleus, whereas light scattering at large angles is determined by fractal scattering by subcellular structures. The findings are consistent with the results of experimental investigation of the contributions of different cellular components to light scattering by cells.
