  • A colloidal particle straddling an air/water interface experiences an unexpectedly large viscous drag.

  • The exterior surface of cell membranes in eukaryotes is surrounded by glycans. It is now found that the spatial configuration of these polysaccharide molecules controls the phase behaviour of multiphase lipid membranes—either by stabilizing ordered lipid domains or by suppressing macroscopic lipid phase separation—and that this glycan-induced patterning is thermally reversible.

  • Colloidal particles adsorbed at liquid interfaces are commonly assumed to be at equilibrium, but holographic microscopy experiments now reveal that microspheres bound to a water/oil interface may take months to equilibrate. The observed ageing dynamics agree with a model of thermally activated hopping of the particle/interface contact line over nanoscale surface defects, and have implications for understanding the interactions between adsorbed colloidal particles.

  • The potential control over the properties of colloidal crystals makes them interesting for applications in optical devices as photonic crystals. Here, Kim et al. demonstrate that the optical properties of rubber capsules in a microfluidic device can be tuned via osmotic pressure.

  • Holographic microscopy is based on collecting holograms, patterns of dark and light fringes, and analysing them to obtain information about the specimen’s properties. This Primer introduces in-line holographic microscopy, with a focus on three analysis methods: generative modelling, machine learning and hybrid approaches.

  • A general method of creating colloidal particles that can self-assemble into ‘colloidal molecules’ is described: surface patches with well-defined symmetries are functionalized using DNA with single-stranded sticky ends and imitate hybridized atomic orbitals to form highly directional bonds.

  • Grafting DNA strands onto colloidal nano- and microparticles endows them with sequence-specific interactions. This Review explains how these interactions emerge from reactions between the strands and how the DNA sequences can add information that tells the particles how to self-assemble.
