For example, think of how sugar dissolves in water, making a homogenous solution. On the other hand, if larger particles are used, such as grains of sand, they will not dissolve in the water.

Colloidal silver is a dangerous, toxic, product and is unfit for consumption. ... Colloidal silver is a solution containing very small silver particles suspended in a liquid.

Colloidal nanocrystals are solution-grown, nanometre-sized, inorganic particles that are stabilized by a layer of surfactants attached to their surface. The inorganic cores possess useful ...

When the electrode is dipped into the colloidal solution, its charged tip polarizes each sphere. These induced dipolar interactions cause the spheres to link together. A resulting chain could contain ...

Multiphoton-pumped lasing from semiconductor nanocrystals in solution is difficult due to Auger recombination, low volume fraction and high threshold. Here, Li et al. demonstrate photostable ...
