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 ...
