Motile bacteria are selectively attached to submicrometer‐scale cargo immobilized on gold patterns on a silicon substrate using surface chemistry and the specificity of antibody‐based capture. The bacteria–cargo conjugates can be released on‐demand from the surface with benign chemicals, and the motile bacteria are observed to propel their cargo in solution.
