“…Moreover, the time resolution of the signal is low, without the ability to be resolved in space. Another important issue that the vibration sample magnetometer has to face is the signal-to-noise ratio, which should be even more improved for this device to achieve accurate measurements [65]. In addition, according to [66], the VSM method demands a significant amount of time, and for this reason, it is not very efficient for clinical applications.…”

“…The most important studies that use vibration sample magnetometers for nanoparticle materials characterization purposes are summarized below. Analytically, in [65], γ-Fe 2 O 3 particles, used for medical applications are measured through a vibrating sample magnetometer. In [66], a vibrating sample magnetometer is used to provide magnetic information about formalin-fixated lymph nodes, with the further aim of this information to be used to construct a clinical magnetometer, instead of the vibrating sample magnetometer.…”

This article sums up and compares the most important techniques for magnetic sensing of ferromagnetic nanoparticles. In addition, the most well-known magnetic sensing instruments are presented, while the advantages and disadvantages of each instrument category are summarized. Finally, a measurement system based on fluxgate magnetometers is proposed for the magnetic characterization of a cobalt-based material applicable in the catalysis process. The authors conclude that this arrangement can provide ferromagnetic material sensing with the most advantages for this catalysis application. Indeed, as nanoparticle materials can be used in many applications, like catalysis, their properties and the phase of the catalyst should be known at any time. Moreover, as the industrial processes operate at a rapid pace, the need for simple, fast, and low-cost measurement systems that will also enable in vivo material characterization is rising. Consequently, this article aims to propose the best candidate magnetic sensing method as well as the best candidate instrument for every application based on the advantages and disadvantages of each sensor.

This paper presents a method that has been developed to determine the quantity of accumulated magnetic particles in mice tissues using magnetization measurements. Dispersions of platelet Fe 3 O 4 particles with sizes of 30-50nm and a saturation magnetization of approximately 80 Am 2 /kg were intravenously administered to mice. Primary tissues were dried to measure the magnetization. The amounts of Fe 3 O 4 particles accumulated in the tissues were obtained by dividing the magnetization of tissues by the magnetization of Fe 3 O 4 particles under a magnetic field of 39.8 kA/m. A remarkable accumulation of particles was observed in the liver and spleen, being supported by the observation of tissues using Prussian blue staining. Total Fe 3 O 4 particles accumulated in primary tissues was approximately 38-40 wt% and 40-44 wt% against the particles in administered dispersions with 3.0 wt% and 0.4 wt% contents,respectively. The method developed in the study is considered to be effective for verifying magnetic hyperthermia and thermoablation therapies, in which the quantity of accumulated particles directly reflects the heating power required for those therapies.
