Understanding the deposition of micro- or nano-particles is central to designing innovative bioassays, biosensors, functional surfaces and ink-jet printing. An evaporating droplet containing colloidal ...

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

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

Colloidal self-assembly is a process where colloidal particles spontaneously organize into ordered structures under specific conditions. Colloidal self-assembly serves as a foundation for designing ...

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 lithography is a nanofabrication technique that utilizes colloidal particles as masks for creating ordered nanostructures on substrates. This cost-effective and scalable method has gained ...

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, ...

Engineers discover unusual properties in magnetized colloids that surprisingly adhere to the physics described by Kelvin's equation, which models the thermodynamics of molecular systems. Small spheres ...

Crystals -- from sugar and table salt to snowflakes and diamonds -- don't always grow in a straightforward way. Researchers have now captured this journey from amorphous blob to orderly structures. In ...

DNA is a fascinating macromolecule that guides protein production and enables cell replication. It has also found applications in nanoscience and materials design. Colloidal crystals are ordered ...
