  By employing a series of massively parallel ab-initio simulations, we study
how optical forces act on biological matter subject to morphological disease.
As a representative case study, we here consider the case of Plasmodium
Falciparum on red blood cells (RBC) illuminated by a monochromatic plane wave.
Realistic parameters for the geometry and the refractive index are then taken
from published experiments. In our theoretical campaign, we study the
dependence of the optical force on the disease stage for different incident
wavelengths. We show that optical forces change significantly with the disease,
with amplitude variation in the hundreds of pN range. Our results open up new
avenues for the design of new optical systems for the treatment of human
disease.
