Researchers have devised a method for following the gelation of colloidal gels. Their confocal microscopy technique has allowed the different stages of the process to be analyzed, leading to insights ...

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 ...

Researchers have developed a model system for so-called soft colloids. The model gives us a better understanding of correlations between the atomic structure of colloids and their perceptible material ...

Nanosized drug particles and colloids enhance drug permeability and bioavailability through the particle drifting effect, but outcomes vary by drug, colloid, and formulation. This study used biphasic ...

Nanotechnology is generally seen as a relatively new invention. It is generally accepted to have been officially born as a discipline with Richard Feynman's 1959 lecture, "There's plenty of room at ...

Nature keeps a few secrets. While plenty of structures with low symmetry are found in nature, scientists have been confined to high-symmetry designs when synthesizing colloidal crystals, a valuable ...

“Colloid” means that something is dissolved in another substance. Colloidal silver is made up of tiny particles of silver in water. It’s the same kind of silver used in jewelry and silverware. The ...
