Continuous Flow Low Gradient Magnetophoresis of

2021-6-2  In recent years, magnetophoresis of magnetic nanoparticles (MNPs) has been emerged as one of the most appealing separation technologies in water treatment and biomedical applications. Magnetophoresis of MNPs can be further divided into two classes: high gradient magnetic separation (HGMS) and low gradient magnetic separation (LGMS). In the past decades, LGMS has been

Working principle and application of magnetic separation ...

IntroductionMagnetic Separation in Isolation of Target Entity For Diagnostic PurposeStrategies of Magnetic Separator DesignConcluding Remarks and Future ConsiderationsAuthors' ContributionsFundingFast, selective and accurate detection of diseases is critical in clinical diagnosis as it allows physicians to provide more precise and preliminary medical assessments to patients. However, biological samples are usually exceptionally complex due to the presence of multiple components. In order to perform disease diagnosis, it is essential to isolate the specific target entity (which is the infectious agent to be detected) from the complex raw samples. This sample preparation step is needed prior to analysis in order to spe

Low-field Magnetic Separation of Monodisperse Fe3O4 ...

Magnetic separations at very low magnetic field gradients (<100 tesla per meter) can now be applied to diverse problems, such as point-of-use water purification and the simultaneous separation of complex mixtures. High-surface area and monodisperse magnetite (Fe3O4) nanocrystals (NCs) were shown to respond to low fields in a size-dependent fashion.
