From spectral analysis to hysteresis loops: a breakthrough in the optimization of magnetic nanomaterials for bioapplications

Abstract An innovative method is proposed to determine the most important magnetic properties of bioapplication-oriented nanomaterials exploiting connection between hysteresis loop and frequency spectrum magnetization. Owing conceptual practical simplicity, may result in a substantial advance optimization for use precision medicine. The techniques analysis magnetization currently applied both vitro vivo usually give limited, qualitative picture effects active biological environment, have be complemented by direct measurement loop. We show that very same can used convey all information needed present-day biomedical applications without necessity doing conventional measurements experimental conditions. spectral harmonics obtained analysing response tracer frequency, as particle spectroscopy/imaging, are demonstrated lead precise reconstruction loop, whose parameters (loop’s area, remanence coercive field) directly through transformation formulas based on simple manipulation amplitudes phases. validity experimentally verified various bioapplications submitted ac fields different amplitude, waveform. In cases, data taken domain exactly reproduce from measurements.
