Phase contrast imaging time lapse shows short rod rafts assembled into a trimeric structure do not relax into an equilateral configuration in a colloidal membrane composed of an achiral mixture of left- and right-handed long rods. Scale bar is 2 μm. Conformational switching of chiral colloidal rafts regulates raft–raft attractions and repulsions Joia M.
