Quantitative phase imaging (QPI) is a label-free, wide-field microscopy approach with
significant opportunities for biomedical applications. QPI uses the natural phase shift of light …

Polymer networks are complex systems consisting of molecular components. Whereas the
properties of the individual components are typically well understood by most chemists …

Proteins and nucleic acids can phase-separate in the cell to form concentrated biomolecular
condensates,,–. The functions of condensates span many length scales: they modulate …

Cells can enter into a dormant state when faced with unfavorable conditions. However, how
cells enter into and recover from this state is still poorly understood. Here, we study …

Controlling interfaces of phase-separating fluid mixtures is key to the creation of diverse
functional soft materials. Traditionally, this is accomplished with surface-modifying chemical …

Since their invention in 1986 by Arthur Ashkin and colleagues, optical tweezers have
become an essential tool in several fields of physics, spectroscopy, biology …

A ubiquitous observation in cell biology is that the diffusive motion of macromolecules and
organelles is anomalous, and a description simply based on the conventional diffusion …

We review what is currently understood about how the structure of the primary solid
component of mucus, the glycoprotein mucin, gives rise to the mechanical and biochemical …

Hydrogels are materials used in a variety of applications, ranging from tissue engineering to
drug delivery. The incorporation of nanoparticles to yield composite hydrogels has gained …

The locomotion of microorganisms and spermatozoa in complex viscoelastic fluids is of
critical importance in many biological processes such as fertilization, infection, and biofilm …
