Controlled assembly of bacteria on chemical patterns using soft lithography

Highly ordered arrays of single living bacteria were obtained by selective adsorption of bacteria onto chemical patterns with micrometric resolution. The chemically engineered template surfaces were prepared with the combination of microcontact printing process and a simple incubation technique. This methodology can be used for fundamental studies of bacteriumʹs inner mechanisms and sub-cellular organization as well as for interfacing living bacteria with artificial microsystems.
