A cellular-level study of the pathophysiology is crucial for understanding the mechanisms
behind human diseases. Recent advances in quantitative phase imaging (QPI) techniques …

Particle tracking is a fundamental technique for investigating a variety of biophysical
processes, from intracellular dynamics to the characterization of cell motility and migration …

This paper discusses the current state of underwater optical imaging in the context of
physics, technology, biology, and history. The paper encompasses not only the history of …

Dynamic tracking of human sperms across a large volume is a challenging task. To provide
a high-throughput solution to this important need, here we describe a lensfree on-chip …

The quantification of three-dimensional (3D) flow structures and particle dynamics is crucial
for unveiling complex interactions in turbulent flows. This review summarizes recent …

Understanding how bacteria move close to surfaces is crucial for a broad range of microbial
processes including biofilm formation, bacterial dispersion, and pathogenic infections. We …

We present the first time-resolved measurements of the oscillatory velocity field induced by
swimming unicellular microorganisms. Confinement of the green alga C. reinhardtii in …

Digital holographic microscopy (DHM) is a potent tool to perform three-dimensional imaging
and tracking. We present a review of the state-of-the-art of DHM for three-dimensional …

Particle characterization in dispersed multiphase flows is important in quantifying transport
processes both in fundamental and applied research: Examples include atomization and …

For decades, high densities of the dinoflagellate Karlodinium veneficum have been
associated with aquatic faunal mortalities worldwide. This small (< 8–12μm) athecate …
