Conditions can get rough in the micro- and nanoworld. For example, to ensure that nutrients can still be optimally ...

An international team has developed spherical colloidal particles for the visualization of rotational dynamics. The two-color fluorescent particles have an off-center core that allows tracking of ...

Have you ever spilled coffee on a solid surface such as the floor, table or clothing? Most of us have had the experience, but if you have not, or if you are curious, spill just a drop and let it dry ...

Colloidal suspensions heterogenous mixtures of particles with diameters of about 2-500 nanometers, which are permanently suspended in a second phase, usually a liquid. Owing to the small particle size ...

Princeton chemical engineers accurately represented colloidal systems using a maximum of four colloidal particles, shown here in blue, and their oppositely charged counterparts, called counterions, ...

A collaboration between the University of Konstanz and Forschungszentrum Jülich has achieved the first fully tunable experimental realization of a long predicted "swarmalator" system. The study, ...

Urine is a highly saturated solution of extremely complicated composition. Its basic organic constituents are urea, uric acid and its salts, formed by the oxidation of purines. In that fluid, ...

Colloidal gold consists of microscopic particles of gold suspended in liquid and is usually red or purple. It comes from shale or clay deposits. There has been much debate about the health benefits of ...

A recent Instagram post touted the health benefits of colloidal silver, a liquid with tiny silver particles, noting that unless you’re allergic to silver, it’s "harmless to all living creatures." ...
