Abstract
The ability to assemble three-dimensional structures using diamagnetic particles suspended in solutions containing paramagnetic cations is described. The major advantages of this separation device are that: (i) it is a simple apparatus that does not require electric power (a set of permanent magnets and gravity are sufficient for the diamagnetic separation and collection system to work); ii) the assembled structures can be removed from the paramagnetic solution for further processing after fixing the structure; iii) the assembly is fast; and iv) it is small, portable.
