Abstract

A self-assembling structure using non-equilibrium driving forces leading to “living crystals” and other maniputable particles with a complex dynamics. The dynamic self-assembly assembly results from a competition between self-propulsion of particles and an attractive interaction between the particles. As a result of non-equilibrium driving forces, the crystals form, grow, collide, anneal, repair themselves and spontaneously self-destruct, thereby enabling reconfiguration and assembly to achieve a desired property.

First claim

What is claimed is:

1. A method of controlling structure formation of a plurality of particles to achieve reconfigured structures having a desired selectable property, comprising:
applying a non-equilibrium driving force to a plurality of bimaterial colloids;
inducing attractive interaction between each of the plurality of bimaterial colloids; and
forming a structure comprised of a reconfigured plurality of bimaterial colloids having the desired selectable property.

2. The method of claim 1 , wherein the structure is a living crystal.

3. The method of claim 1 , wherein the non-equilibrium driving force is osmotic.

4. The method of claim 1 , wherein the attractive interaction is phoretic.

5. The method as defined in claim 1 wherein at least one of the non-equilibrium driving force and the attractive interaction arise from a magnetic force or a photonic force.

6. The method as defined in claim 1 wherein the desired selectable property is selected from the group of a mechanical property, an electrical property, a chemical property and a photonic property.

7. The method as defined in claim 1 wherein the structure is reconfigured by healing defects in the structure.

8. A method of controlling structure formation of a plurality of particles to achieve reconfigured structures having a desired selectable property, comprising:
applying a non-equilibrium driving force to a plurality of particles;
inducing attractive interaction between each of the plurality of particles; and
forming a living crystal structure comprised of a reconfigured plurality of particles having the desired selectable property.

9. The method of claim 8 , wherein the non-equilibrium driving force is osmotic.

10. The method of claim 8 , wherein the attractive interaction is phoretic.

11. The method as defined in claim 8 wherein at least one of the non-equilibrium driving force and the attractive interaction arise from a magnetic force or a photonic force.

12. The method as defined in claim 8 wherein the desired selectable property is selected from the group of a mechanical property, an electrical property, a chemical property and a photonic property.

13. A method of controlling structure formation of a plurality of particles to achieve reconfigured structures having a desired selectable property, comprising:
applying a non-equilibrium driving force to a plurality of particles;
inducing attractive interaction between each of the plurality of particles; and
forming a structure reconfigured by healing defects and comprised of a reconfigured plurality of particles having the desired selectable property.

14. The method of claim 13 , wherein the structure is a living crystal.

15. The method of claim 13 , wherein the non-equilibrium driving force is osmotic.

16. The method of claim 13 wherein the attractive interaction is phoretic.

17. The method as defined in claim 13 wherein at least one of the non-equilibrium driving force and the attractive interaction arise from a magnetic force or a photonic force.

18. The method as defined in claim 13 wherein the desired selectable property is selected from the group of a mechanical property, an electrical property, a chemical property and a photonic property.
