Abstract: The present invention provides a method for self-replication of multimers of nucleic acid origami tiles by exponentially amplifying the multimer from initial seeds of monomeric units of nucleic acid origami tiles and also provides for the selective exponential amplification of a designated multimer, such as with specific properties or characteristics, over one or more competing multimers in the presence of a mixture of monomers for each of the possible multimers. The selection of the designated multimer based on an environmental change allows the designated multimer to outgrow all competing multimers.

Abstract: The invention provides micron and sub-micron scale particles designed to recognize and selectively interact with each other by exploiting the recognition and specificity enabled by DNA-sequence-encoded coatings. Such materials possess sufficient information coded in their chemical and physical interactions to self assemble and self replicate. The invention further provides methods of using such materials to create self replicating and organizing materials. Replicated copies are permanently linked and then thermally detached, freeing them to act as templates for further growth. This new class of condensed matter systems, provides means to design and control the structure and function of materials and machines from the microscopic to life-size. In another aspect of the invention, depletion type forces and depletion zones can be utilized in the implementation of the self assembly and self replication of materials, including without limitation colloidal particles.

Abstract: A polynucleic acid nanomechanical device with a linear array of alternating PX-JX2 devices and nucleic acid multi-crossover motifs that facilitate the assembly of a nucleic acid strand and functions as an artificial ribosome by translating a nucleic acid signal into an unrelated nucleic acid sequence.

Abstract: The present invention relates to a copolymer termed a ladder copolymer because it has two backbones that serve as legs/sides of a ladder structure. These two backbones, one of which is a nucleic acid or nucleic acid-like polymer, are linked together as the legs/sides of a ladder are linked together by the rungs.

Abstract: Two dimensional polynucleic acid arrays are assembled from robust nucleic acid motifs as polygonal units. The polygonal units in an array have edges composed of nucleic acid multi-crossover domains and are joined together by double cohesion of adjacent polygonal units. A subset of polygonal units in the array have a nanoparticle or pendant molecule attached to an end of one edge of each polygonal unit within this subset.

Abstract: Robust nucleic acid arrays and lattices are assembled based on double crossover cohesion of polygonal units whose edges are composed of nucleic acid multi-crossover domains.

Abstract: A nucleic acid-based translation system where the components of a nucleic acid multicrossover molecule serve as message, translation device and part of the translated product. One continuous strand of a nucleic acid multicrossover molecule acts as a message, which nucleic acid crossover strands, functioning together as a translation device, translate into nucleic acid product strands. Organic molecules appended to the backbone of the nucleic acid product strands can also be polymerized to form a polymer sequence of appended organic molecules.

Abstract: A multiped, capable of traveling in more than one direction along a molecular path in a nano-robotic system where the steps taken by the feet of the multiped are controlled in a sequence specific fashion, is presented. The feet of the multiped dock to footholds on the molecular path via cohesion with “set” molecules and are released from the footholds through the introduction of “unset” molecules that detach or strip away the “set” molecules.

Abstract: One, two and three dimensional structures may be synthesized or modified from polynucleotides. A core structure is expanded by cleavage of a loop with a restriction endonuclease and ligating another polynucleotide to the sticky ends so that the recognition site of the restriction enzyme is not reformed. This process is repeated as many times as necessary to synthesize any desired structure. The structures formed have a wide range of uses.

Abstract: The invention discloses an n-connected closed covalent three-dimensional structure of oligonucleotides, n being at least 3, and methods for making and using same.
