Colloids

Colloids are particles that have a diameter of between approximately 1 and 1,000 nanometres and that are evenly dispersed in fluids. Colloids are also known as colloidal dispersions because the particles remain dispersed and don't settle to the bottom.

    The flagella of microorganisms have provided inspiration for many synthetic devices, but they’re typically not easy to produce. A new class of swimmer makes it look simple by spontaneously growing a tail that it can whip to self-propel.

    Colloidal self-assembly requires carefully balanced particle interactions that are often incompatible with the mechanical disturbances associated with macroscopic-scale manufacturing. Now, a practical bottom-up route has enabled the production of bulk solid materials with nanoscale components.
