Forget 3D printing—DNA and water now build tiny machines that assemble themselves

Columbia researchers have developed a method for creating complex 3D nanostructures using DNA self-assembly. This technique, inspired by biological systems, allows for the fabrication of targeted nanoscale materials with applications in light manipulation, computing, catalysis, and more. The process uses DNA origami to create building blocks that assemble into desired structures, offering a faster and more environmentally friendly alternative to traditional nanofabrication methods.
