Magnetic-Particle-Sensing Based Diagnostic Protocols and Applications
Sensors, 2015 Magnetic particle-labeled biomaterial detection has attracted much attention in recent years for a number of reasons; easy manipulation by external magnetic fields, easy functionalization of the surface, and large surface-to-volume ratio, to name but a ...

Sedimentation of a suspension of paramagnetic particles in an external magnetic field [PDF]
Phys. Rev. E 102, 023101 (2020), 2019 We investigate the sedimentation of initially packed paramagnetic particles in presence of a homogeneous external magnetic field, in a Hele-Shaw cell filled with water. Although the magnetic susceptibility of the particles is small and the particle-particle induced magnetic interactions are significantly smaller compared to the gravitational ...

High-gradient magnetic chromatography of rare-earth elements
AIP AdvancesHigh-gradient magnetic chromatography (HGMC) is the chromatographic separation of a mixture of magnetic particles using high-gradient magnetic separation (HGMS) systems. However, unlike HGMS which has traditionally been used to separate magnetic from non-

Ratchet Effect in Magnetization Reversal of Stoner Particles [PDF]
Phys. Rev. B 73, 092416 (2006), 2005 A new strategy is proposed aimed at substantially reducing the minimal magnetization switching field for a Stoner particle. Unlike the normal method of applying a static magnetic field which must be larger than the magnetic anisotropy, a much weaker field, proportional to the damping constant in the weak damping regime, can be used to switch the ...

Application of atomic magnetometry in magnetic particle detection [PDF]
, 2006 We demonstrate the detection of magnetic particles carried by water in a continuous flow using an atomic magnetic gradiometer. Studies on three types of magnetic particles are presented: a single cobalt particle (diameter ~150 um, multi-domain), a suspension of superparamagnetic magnetite particles (diameter \~1 um), and ferromagnetic cobalt ...

Sensors, 2009 Many types of biosensors employ magnetic nanoparticles (diameter = 5–300 nm) or magnetic particles (diameter = 300–5,000 nm) which have been surface functionalized to recognize specific molecular targets.

Collisionless particle dynamic in an axi-symmetric diamagnetic trap [PDF]
arXiv, 2020 Particle dynamic in an axi-symmetric mirror machine with an extremely high plasma pressure equal to pressure of vacuum magnetic field (so-called regime of diamagnetic confinement) is investigated. Extrusion of magnetic field from central region due to plasma diamagnetism leads to non-conservation of the magnetic moment and can result in chaotic ...

Particle dynamics in non-rotating Konoplya and Zhidenko black hole immersed in an external uniform magnetic field [PDF]
arXiv, 2022 In this paper, we investigate the dynamics of particles in the background of non-rotating Konoplya and Zhidenko black hole that is immersed in an external uniform magnetic field. The work involves circular motion of electric and magnetic particles and particle acceleration. First the motion of electric charged particles is considered.
