Special Issue Information

Dear Colleagues,

Many sophisticated research experiments and applications rely on the measurement of extremely weak magnetic fields (biomagnetism, nanomagnetism, molecular magnetism, magnetic microscopy, etc.). Hence, in recent decades, many efforts have been devoted toward the development of different ultrasensitive magnetic sensors, such as the atomic magnetometer based on the detection of the Larmor spin precession of optically pumped atoms, hybrid magnetometers based on giant magnetoresistance spin valves, diamond magnetometers based on nitrogen-vacancy centers in room-temperature diamond, and micro and nano superconducting quantum interference devices (SQUIDs). In addition, in the last years, molecular magnetism with the re-introduction of lanthanide ions as spin carriers in magnetic molecules is very promising in view of the applications to spintronic devices, qubit, and multifunctional materials.

The aim of this Special Issue is to present an overview of the development of magnetic quantum sensor and their applications. Both original research articles and reviews are encouraged.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Magnetochemistry is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The sentinel lymph node is the first lymph-node-draining cancer metastasis. The identification of the sentinel lymph node using magnetic particles and a magnetic sensor has attracted attention in recent years, as this method is less invasive than the conventional method of radiotracer injection. However, the development of a two-dimensional measurement method for sentinel lymph nodes using magnetic nanoparticles remains an issue. In the present study, a method and apparatus for the two-dimensional imaging of magnetic particle distribution were developed to detect a lymph node with magnetic particles concentrated within lymphoid tissues. The method comprises the reconstruction of the magnetic field measured with a high-sensitivity magnetic sensor and with a magnetic detection ability of 2 nT/√Hz at 100 Hz (5 nT/√Hz at 1 Hz). The proposed system measures the two-dimensional magnetic field distribution in an area of up to 25 × 25 mm2 using a coil generating a 0.77 mT external magnetic field applied to the measurement target. The improved spatial resolution of the images makes it possible to use two-dimensional imaging for diagnostics of breast cancer metastases. Full article
