Microtraction engines made from colloidal chains

Researchers have devised a new method to transport micro cargo – by attaching it to chains of colloidal particles that wiggle their way through liquid crystals.

The research team, led by Hiroshi Orihara from Hokkaido University, Japan, and Christian Bahr from the Max Planck Institute for Dynamics and Self-Organization, Germany, created colloidal ‘caterpillars’ from surface-modified silica particles which self-assemble into chains when placed in a liquid crystal medium.
