Occasionally referred to as ‘colloidal gold,’ gold colloid is a suspension comprising sub-micron gold nanoparticles suspended in a solvent - most commonly water. Gold nanoparticles' distinct ...

Imagine a "smart fluid" whose internal structure can be rearranged just by changing temperature. In a new study published in Matter, researchers report a way to overcome a long-standing limitation in ...

Scientists have devised a way of fabricating a complex structure, previously found only in nature, to open up new ways for manipulating and controlling light. Scientists have devised a way of ...

Lateral flow immunoassays, also called immunochromatography strips, are straightforward devices used to detect the absence or presence of a target analyte. Target analytes range from pathogens to ...

Fluids containing nano- to micrometer scale “colloidal” particles are found universally in nature and technology. Coatings, consumer products, filters, cosmetics, food, pharmaceuticals, and numerous ...
