The diamagnetic properties of these cells and the force exerted on them along the {\ensuremath{<}}i{\ensuremath{>}}z{\ensuremath{<}}/i{\ensuremath{>}}-axis have been investigated. The diamagnetic levitation height of each cell has been both theoretically calculated and experimentally studied. The results open a novel possibility for positioning living cells with further applications to medical diagnostics.} }
