Vibrating Sample Magnetometry. Please provide hysteresis loop data (EMU/g Vs. applied field in mTesla), remanence, and saturation magnetization. Please apply correction to any distortion of hysteresis loop from liquid sample. Rxn2 sample is provided as 0.03598 % (w/w) Fe2O3. Sample is non-hazardous and consists of iron oxide nanoparticles with a carbohydrate coating and attached antibody in an aqueous phosphate-buffered saline and EDTA buffer.
