Abstract

The invention provides compositions and methods relating to self-assembly of structures of various size and shape complexity. The composition include synthetic single-stranded polymers having a backbone and pre-determined linear arrangement of monomers.

First claim

What is claimed is:

1. A synthetic, non-nucleic acid structure comprising:
a first heterogeneous plurality of non-nucleic acid monomers attached in a pre-determined manner to a first non-nucleic acid polymeric backbone; and
a second heterogeneous plurality of non-nucleic acid monomers attached in a pre-determined manner to a second non-nucleic acid polymeric backbone, wherein monomers of the first plurality have complementary shapes, mirror image magnetic configurations, and opposite N/S polarity relative to monomers of the second plurality, and wherein monomers of the first plurality are bound to monomers of the second plurality through magnetic attraction and shape complementarity.

2. The structure of claim 1 , wherein the structure is linear.

3. The structure of claim 1 , wherein the structure is branched.

4. The structure of claim 1 , wherein the first non-nucleic acid polymeric and the second non-nucleic acid polymeric backbone are comprised of plastic, metal or semiconductor material.

5. The structure of claim 1 , wherein the structure comprises 2 to 100 different monomers.

6. The polymer of claim 1 , wherein monomers in the first and second pluralities are comprised of plastic, hydrogel, metal, semiconductor material or a combination thereof.

7. The structure of claim 1 , wherein monomers in the first and second pluralities range from 10 nanometers to 10 meters.

8. The structure of claim 1 , wherein monomers in the first and second pluralities are attached to the first backbone and second backbone, respectively, by an adhesive, a molten material, a mechanical fitting, a molecular interaction or a combination thereof.

9. The structure of claim 1 , wherein monomers in the first and second pluralities further comprise an attachment moiety.

10. A composition comprising one or more structures of claim 1 .

11. A synthetic, non-nucleic acid structure comprising:
a first heterogeneous plurality of monomers attached in a pre-determined manner to a first backbone comprised of plastic, metal or semiconductor material; and
a second heterogeneous plurality of monomers attached in a pre-determined manner to a second backbone comprised of plastic, metal or semiconductor material,
wherein monomers of the first plurality have complementary shapes, mirror image magnetic configurations, and opposite N/S polarity relative to monomers of the second plurality,
wherein monomers of the first plurality are bound to monomers of the second plurality through magnetic attraction and shape complementarity, and
wherein the monomers in the first and second heterogeneous pluralities are comprised of plastic, hydrogel, metal, semiconductor material or a combination thereof.

12. The structure of claim 11 , wherein the monomers in the first and second heterogeneous pluralities are attached to the backbone by an adhesive or mechanical fitting.

13. A synthetic, non-nucleic acid structure comprising:
a first heterogeneous plurality of plastic monomers attached in a pre-determined manner to a first plastic backbone; and
a second heterogeneous plurality of plastic monomers attached in a pre-determined manner to a second plastic backbone,
wherein monomers of the first plurality have complementary shapes, mirror image magnetic configurations, and opposite N/S polarity relative to monomers of the second plurality, and
wherein monomers of the first plurality are complementary to and bound to monomers of the second plurality through magnetic attraction and shape complementarity.

14. The structure of claim 11 , wherein the structure is linear.

15. The structure of claim 11 , wherein the structure is branched.

16. The structure of claim 11 , wherein the structure comprises from 2 to 100 different monomers.

17. The structure of claim 13 , wherein the monomers in the first and second heterogeneous pluralities are attached to the first backbone and the second backbone, respectively, by an adhesive or mechanical fitting.

18. The structure of claim 13 , wherein the structure is linear.

19. The structure of claim 13 , wherein the structure is branched.

20. The structure of claim 13 , wherein the structure comprises 2 to 100 different monomers.
