3d DNA self assembly

Caption

Chip-integrated 3D nanostructured device fabricated using DNA self-assembly (Left panel). A DNA crystal is grown at a designated substrate location (about 1000 crystals on 5μm pads are shown on a Right panel), then mineralized to silica and volumetrically templated with a semiconductor material before electrodes are attached (Center panel). The resulting device exhibits an electrical response when exposed to light. Thousands of such 3D devices can be grown in parallel using this bottom-up fabrication approach.
