What is it about?
We fabricated micro-magnets using ink jet printer. Printing solution contained Fe3O4 nanoparticles. Micro-magnets have a parallelepiped shape with a surface area of 100x100 micro-meter and a thickness of 40 micro-meter. The distance between magnets is 100 micro-meter. Micro-magnets generated magnetic field with a strength of 0.2 T and a gradient of 2.8 x 10^3 T/m that was enough to levitate breast cancer cells T47D.

Why is it important?
Fabrication method is simple, fast, and low-cost. Structures and magnetic properties of micro-magnets can be easily controlled.
Perspectives
Such micro-magnets can be applied to levitate and separate many types of cells.
