PERDIX - Fabricate any free-form 2D drawing at the nanometer scale using DNA (MIT)
PERDIX (Programmed Eulerian Routing for DNA Designs using X-overs) is a free, open-source resource for the fully autonomous design of arbitrary 2D scaffolded DNA origami nanostructures.
TALOS (Three-dimensional, Algorithmically-generated Library of DNA Origami Shapes) is a open-source, fully autonomous design algorithm for generating 3D nanometer-scale structures using DNA.
