Green algae scatter off sharp viscosity gradients

Journal article

The present work contains original research on the field of biophysics, specifically the study of swimming bacteria. Swimming microorganisms can be modeled as active particles moving at low Reynolds number (Re ≪ 1) and subject to different sources of noise. The term “active” means that they are self-propelled, while Re ≪ 1 implies that their motion is dominated by viscous stresses, therefore relying on non-reciprocal deformations in time, in order to achieve movement. Noise arises from therma...
