Levitation and position of T47D cells on a magnetic microsystem fabricated by ink jet printing

We present the levitation and residing at particular places of human breast cancer (T47D) cells on a magnetic microsystem quickly fabricated by printing. The consists arrays soft elements is put adjacent to bulk magnet. Under field generated magnet, are magnetized, obtaining significant strength high gradient in micro-space above them. applies force as they dropped surfaces elements. As result, stable position for each cell observed. can be predicted theory that takes into account magnetic, buoyant, gravitational forces cells. Our theoretical experimental results agree well with one another, capable efficient manipulation.
