FIRM evidence : Force‐induced remnant magnetization spectroscopy (FIRMS) is developed to achieve molecular specificity in magnetic imaging. The method measures the magnetization of the magnetic particles as a function of an external disturbing force. As the force‐dissociated magnetic particles have no contribution to the signal, the binding force serves as a spectroscopic parameter for specific molecular and cellular identification (see picture).
