The evaporation of a sessile droplet spontaneously induces an internal capillary liquid flow.
The surface-tension driven minimisation of surface area and/or surface-tension differences …

Recent developments in the studies of evaporation of liquid droplets placed on a solid
substrate are reviewed for the droplet size typically larger than 1 μm, so that kinetics effects …

A control over the nature of deposit pattern obtained after the evaporation of solvent from a
sessile drop containing dispersed materials has been demonstrated to have applications in …

We discuss how the stain left after evaporation of a suspension evolves with heating of the
glass or plastic on which the liquid has been deposited. Upon increasing the substrate …

An evaporating droplet is a dynamic system in which flow is spontaneously generated to
minimize the surface energy, dragging particles to the borders and ultimately resulting in the …

Quantitative experiments on the evaporation from sessile droplets of aqueous saline (NaCl)
solutions show a strong dependence on salt concentration and droplet shape. The …

Evaporating salty droplets are ubiquitous in nature, in our home and in the laboratory.
Interestingly, the transport processes in such apparently simple systems differ strongly from …

Effective point-of-care diagnostics require a biomarker detection strategy that is low-cost and
simple-to-use while achieving a clinically relevant limit of detection. Here we report a …

The microtiter plate has been an essential tool for diagnostics, high-throughput screening,
and biological assays. We present an alternative platform to perform bioassays in a …

Hypothesis The droplets ejected from an infected host during expiratory events can get
deposited as fomites on everyday use surfaces. Recognizing that these fomites can be a …
