Painting with bacteria: Smart templated self assembly using motile bacteria
arXiv:1710.08188 · doi:10.1038/s41467-018-03161-8
Abstract
External control of the swimming speed of `active particles' can be used to self assemble designer structures in situ on the micrometer to millimeter scale. We demonstrate such reconfigurable templated active self assembly in a fluid environment using light powered strains of Escherichia coli. The physics and biology controlling the sharpness and formation speed of patterns is investigated using a bespoke fast-responding strain.
