<jats:p><jats:bold>A novel approach to fabricating multicomponent nanostructures</jats:bold> is demonstrated. Atomic polarization in ferroelectric perovskites is manipulated to control electronic structure and local chemical reactivity (see Figure). Several paradigms for ferroelectric domain patterning are presented. Complex structures consisting of semiconductors, metals, and functional organic/biological molecules are produced.</jats:p>
