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.

    Changing temperature of thermoresponsive microgels is typically used as a proxy for modifying volume fraction based on the assumption that doing so does not alter the interaction potential. Bergman et al. shows that this picture is oversimplified and microgels are better described by a multi-Hertzian model.

    For small scale biological systems such as cilia, movement is achieved by rhythmic motor patterns that organize spontaneously within arrays of driven oscillators. The authors show that conductive spheres oscillating between biased electrodes create similar traveling wave motions which can be used to direct the transport of cargo.

    Monodisperse biaxial colloidal particles are used as model systems to understand the phase behavior of biaxial molecules but high-quality biaxial colloids are limited. Here the authors describe gram-scale synthesis of uniform biaxial colloidal cuboids and their assembly into mesophasic structures.
