Abstract
In one aspect, the present disclosure provides a method for self-assembly of magnetic building blocks, including distributing a plurality of building blocks in a liquid medium, each of the plurality of building blocks having a plurality of stable radicals, establishing a magnetic field interacting with at least a portion of the plurality of building blocks, guiding with the magnetic field the portion of the plurality of building blocks from a first location in the liquid medium to a second location in the liquid medium, assembling into a first construct the portion of the plurality of building blocks proximate the second location, and treating the first construct with at least one antioxidant to neutralize at least in part the plurality of stable radicals.

A method for self-assembly of magnetic building blocks, the method comprising:
- distributing a plurality of building blocks in a liquid medium, each of the plurality of building blocks comprising a plurality of stable radicals;
- establishing a magnetic field interacting with at least a portion of the plurality of building blocks;
- guiding with the magnetic field the portion of the plurality of building blocks from a first location in the liquid medium to a second location in the liquid medium;
- assembling into a first construct the portion of the plurality of building blocks proximate the second location;
- and
- treating the first construct with at least one antioxidant to neutralize at least in part the plurality of stable radicals.
A system for self-assembly of magnetic building blocks, the system comprising:
- a liquid medium;
- a reservoir for containing the liquid medium;
- a plurality of building blocks for distribution in the liquid medium, each of the plurality of building blocks comprising a plurality of stable radicals;
- a magnetic field established relative to the reservoir, the magnetic field interacting with at least a portion plurality of building blocks when the plurality of building blocks are distributed in the liquid medium, the magnetic field operable to guide the portion of the plurality of building blocks from a first location in the liquid medium to a second location in the liquid medium and assemble into a first construct the portion of the plurality of building blocks proximate the second location;
- and
- a composition comprising an antioxidant for treating the first construct to neutralize at least in part the plurality of stable radicals.
A method for self-assembly of magnetic building blocks, the method comprising:
- incubating a plurality of building blocks in a composition comprising a plurality of stable radicals;
- distributing the plurality of building blocks in a reservoir containing a liquid medium;
- establishing a magnetic field with a permanent magnet, the magnetic field encompassing at least a portion of the plurality of building blocks;
- guiding with the magnetic field the portion of the plurality of building blocks from a first location in the liquid medium to a second location in the liquid medium;
- assembling into a first construct the portion of the plurality of building blocks proximate the second location;
- cross-linking the portion of the plurality of building blocks that comprises the first construct;
- and
- treating the first construct with at least one antioxidant to neutralize at least in part the plurality of stable radicals;
- wherein the density of each of the plurality of building blocks is less than the density of the liquid medium such that the plurality of building blocks floats on a surface of the liquid medium.
