Impact of in vitro digested zinc oxide nanoparticles on intestinal model systems
Particle and Fibre Toxicology, 2022 Background Zinc oxide nanoparticles (ZnO NP) offer beneficial properties for many applications, especially in the food sector. Consequently, as part of the human food chain, they are taken up orally. The toxicological evaluation of orally ingested ZnO NP

Hydrodynamic attraction of swimming microorganisms by surfaces
, 2008 Cells swimming in confined environments are attracted by surfaces. We measure the steady-state distribution of smooth-swimming bacteria (Escherichia coli) between two glass plates.

Swimming abilities of temperate pelagic fish larvae prove that they may control their dispersion in coastal areas [PDF]
, 2019 The Sense Acuity and Behavioral (SAAB) Hypothesis proposes that the swimming capabilities and sensorial acuity of temperate fish larvae allows them to find and swim towards coastal nursery areas, which are crucial for their recruitment. To gather further

Swimming Rhythm Generation in The Caudal Hindbrain of The Lamprey [PDF]
, 2018 The spinal cord has been well established as the site of generation of the locomotor rhythm in vertebrates, but studies have suggested that the caudal hindbrain in larval fish and amphibians can also generate locomotor rhythms.

Dispersion of biased swimming microorganisms in a fluid flowing through a tube
, 2010 Classical Taylor-Aris dispersion theory is extended to describe the transport of suspensions of self-propelled dipolar cells in a tubular flow. General expressions for the mean drift and effective diffusivity are determined exactly in terms of axial ...

Unsteady feeding and optimal strokes of model ciliates
, 2012 The flow field created by swimming microorganisms not only enables their locomotion but also leads to advective transport of nutrients. In this paper we address analytically and computationally the link between unsteady feeding and unsteady swimming on a
