Methods of forming structures
A method of forming a structure comprises forming a pattern of self-assembled nucleic acids over a material. The pattern of self-assembled nucleic acids is exposed to at least one repair enzyme to repair defects in the pattern. The repaired pattern of self-assembled nucleic acids is transferred to the material to form features therein. A method of decreasing defect density in self-assembled nucleic acids is also disclosed. Self-assembled nucleic acids exhibiting an initial defect density are formed over at least a portion of a material and the self-assembled nucleic acids are exposed to at least one repair enzyme to repair defects in the self-assembled nucleic acids. Additional methods are also disclosed.

5. The method of claim 1 , wherein forming a nanocomponent on a material exposed through the mask comprises forming the nanocomponent comprising at least one dimension of less than about 50 nm on the material.
6. The method of claim 1 , wherein forming a nanocomponent on a material exposed through the mask comprises forming the nanocomponent comprising a lower defect level than a defect level in the mask of self-assembled nucleic acids.
7. The method of claim 1 , wherein forming a nanocomponent on a material exposed through the mask comprises forming nanowires, gold nanoparticles, semiconductive quantum dots, or fluorescent quantum dots on the material.
8. The method of claim 1 , further comprising removing the mask of self-assembled nucleic acids.
9. A method of forming a structure, comprising:
contacting a pattern of self-assembled nucleic acids with at least one repair enzyme to repair defects in the pattern;
repeating the repair of defects until a reduced threshold level of defect density is achieved; and
transferring the repaired pattern to an underlying material.
10. The method of claim 9 , wherein contacting a pattern of self-assembled nucleic acids with at least one repair enzyme to repair defects in the pattern comprises excising at least one base from the pattern of self-assembled nucleic acids.

forming a self-assembled nucleic acid pattern on a material, the self-assembled nucleic acid pattern comprising defects;
contacting the self-assembled nucleic acid pattern with at least one repair enzyme to repair at least one defect of the defects;
repeating the repair of the defects until a reduced threshold level of defect density is achieved; and
transferring the repaired self-assembled nucleic acid pattern to the material.
16. The method of claim 15 , wherein forming a self-assembled nucleic acid pattern on a material comprises forming the self-assembled nucleic acid pattern substantially completely over a surface of the material.
17. The method of claim 16 , further comprising removing a portion of the self-assembled nucleic acid pattern from the surface of the material.
18. The method of claim 15 , wherein forming a self-assembled nucleic acid pattern on a material comprises forming the self-assembled nucleic acid pattern on at least a portion of the material.
19. The method of claim 15 , wherein forming a self-assembled nucleic acid pattern on a material comprises covalently bonding self-assembled nucleic acids of the self-assembled nucleic acid pattern to the material.
20. The method of claim 15 , wherein forming a self-assembled nucleic acid pattern on a material comprises ionically bonding self-assembled nucleic acids of the self-assembled nucleic acid pattern to the material.
