The study of controlling the moleculat self-assembly of aqueous soft matter is a fundamental scheme across multiple disciplines such as physics, chemistry, biology, and materials science. In this work, we use liquid-crystal polymer networks (LCNs) to control the superstrucutre of one aqueous soft material called lyotropic choromonic liquis crystals(LCLC), which shows spontanenous orientational order by stacking the plank-like molecules into elongated aggregates. We synthesize a layer of patterned LCN flims by a nematic liquid-crystal host in which the spatially varying molecular orientations are predesigned by plasmonic photopatterning. We demonstrate that the LCLC aggregates are oriented parallel to the polymer filaments of the LCN film. This pattern aqueous soft material shows immediate application for controlling the dynamics of swimming bacteria. The demonstrated control of the supramolecular assembly of aqueous soft matter by using a stimuli-responsive LCN film will find applications in designing dynamic advacned materials for bioengineering applicaitons..
