Single bacterial cell detection with nonlinear rotational frequency shifts of driven magnetic microspheres
Shifts in the nonlinear rotational frequency of magnetic microspheres, driven by an external magnetic field, offer a dynamic approach for the detection of single bacterial cells. We demonstrate thisExpand
