Force‐Induced Remnant Magnetization Spectroscopy for Specific Magnetic Imaging of Molecules

Detection of magnetic nanomaterials in molecular imaging and diagnosis applications

“…A recently developed technique based on AM solved the issue of lacking a spectroscopic parameter in magnetic sensing. This technique, termed as force-induced remnant magnetization spectroscopy (FIRMS), implements the binding force of the noncovalent bonds between the ligand on the MNPs and the targeted receptor molecules as a molecular signature for distinguishing different molecular interactions [165,166]. The principle is shown in Figure 11.…”

Recent advances in biological detection with magnetic nanoparticles as a useful tool

“…By modifying MNPs with antibodies, they successfully used scanning imaging of MNPs for quantitative molecular imaging [78]. Besides antibodies, MNPs can also be modified with cells by specific interactions between the target molecules on cells and the ligand molecules conjugated on MNPs [79].…”

Applications of optically detected MRI for enhanced contrast and penetration in metal

“…Disciplines that can use sensitive atomic magnetometers include magnetic resonance imaging (MRI) [5,6], nuclear magnetic resonance [7,8], nuclear quadrupole resonance [9], magnetoencephalography [10], and magnetocardiography [11]. Furthermore, several new techniques based on atomic magnetometry have recently been developed, including scanning magnetic imaging and force-induced remnant magnetization spectroscopy, which have extensive applications in molecular and cellular imaging [12][13][14].…”
