Magnetic characteristics of evaluated tracers

Tracer Name	M_sat^# (emu/g Fe)	<H_sat>^† (mT)	D_v^* (nm)	σ_{ln d}^* (unitless, logscale)
Anti-Ly6G SPIO	44 ± 3	4.4	14.8	0.5
VivoTrax^TM	131 ± 1	5.2	9.8	0.2

# At ±1 T, Lake Shore Cryotronics 7400 series Vibrating Sample Magnetometer.

^†Value derived from the full width at half maximum (FWHM) of the point spread function of the particle in an Arbitrary Wave Relaxometer.

* Mean values derived from fit of M(H) curve to the ensemble Langevin from a log-normal distribution of spherical magnetite particles at 290 K

(D_v: mean magnetic diameter; H_sat: saturating field; FWHM: full width at half maximum; M_sat: saturation magnetization; mT: milli-tesla; nm: nanometer).
