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 ...

It is commonly assumed that tiny particles just go with the flow as they make their way through soil, biological tissue, and ...

NYU scientists are using light to precisely control how tiny particles organize themselves into crystals. Their research, published in Chem, provides a simple and reversible method for forming ...

Being abundant in nature, colloids find increasingly important applications in science and technology, ranging from direct probing of kinetics in crystals and glasses to fabrication of ...

Colloidal silica is a mainstay for everyday applications such as papermaking, polishing the silicon wafers used to make computer microchips, making nonslip and abrasion-resistant coatings, and soaking ...

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 ...

Imagine a "smart fluid" whose internal structure can be rearranged just by changing temperature. In a new study published in ...
