Patent number: 11961008Abstract: Methods for controlled segregation of blocks of information encoded in the sequence of a biopolymer, such as nucleic acids and polypeptides, with rapid retrieval based on multiply addressing nanostructured data have been developed. In some embodiments, sequence controlled polymer memory objects include data-encoded biopolymers of any length or form encapsulated by natural or synthetic polymers and including one or more address tags. The sequence address labels are used to associate or select memory objects for sequencing read-out, enabling organization and access of distinct memory objects or subsets of memory objects using Boolean logic. In some embodiments, a memory object is a single-stranded nucleic acid scaffold strand encoding bit stream information that is folded into a nucleic acid nanostructure of arbitrary geometry, including one or more sequence address labels. Methods for controlled degradation of biopolymer-encoded blocks of information in the memory objects are also developed.Type: GrantFiled: October 28, 2022Date of Patent: April 16, 2024Assignee: MASSACHUSETTS INSTITUTE OF TECHNOLOGYInventors: Mark Bathe, Sakul Ratanalert, Remi Veneziano, James Banal, Tyson Shepherd

Publication number: 20230330219Abstract: Compositions containing a nucleic acid nanostructure having a desired geometric shape and immunostimulatory agent(s) bound to its surface are provided. The nanostructures can be, for example, in the form of a 6-helix bundle, or icosahedron, or a pentagonal bipyramid. The nanostructure design allows for control of the relative position and/or stoichiometry of the immunostimulatory agent(s) bound to its surface. The immunostimulatory agent(s) displayed on the nanostructure surface are arranged with the preferred number, spacing, and 3D organization to elicit a robust immune response. The displayed antigen can be a TLR agonist, such as a TLR9 agonist. The immunostimulatory compositions may thus be useful as immunogens, vaccines, adjuvants, and the like. Methods of inducing immune responses, and for targeted induction of TLR activation are also provided.Type: ApplicationFiled: August 11, 2022Publication date: October 19, 2023Inventors: Mark Bathe, Remi Veneziano, Eike-Christian Wamhoff, Tyson Moyer, Benjamin Joseph Read, Rebecca Du, Darrell Irvine

Publication number: 20220383976Abstract: Methods for the top-down design of nucleic acid nanostructures of arbitrary geometry based on target shape of spherical or non-spherical topology are described. The methods facilitate 3D molecular programming of lipids, proteins, sugars, and RNAs based on a DNA scaffold of arbitrary 2D or 3D shape. Geometric objects are rendered as node-edge networks of parallel nucleic acid duplexes, and a nucleic acid scaffold routed throughout the network using a spanning tree formula. Nucleic acid nanostructures produced according to top-down design methods are also described. In some embodiments, the nanostructures include single-stranded nucleic acid scaffold, DX crossovers, and staple strands. In other embodiments, the nanostructures include single-stranded nucleic acid scaffold, PX crossovers and no staples. Modified nanostructures include chemically modified nucleotides and conjugated to other molecules are described.Type: ApplicationFiled: August 2, 2022Publication date: December 1, 2022Inventors: Remi Veneziano, Sakul Ratanalert, Tyson Shepherd, Hyungmin Jun, Mark Bathe
