The target cells are labeled with magnetic nano-particles in a separate tube, container or in a device with soft magnetic collectors but not activated during the labeling period. Labeled biological samples will be used for targets enrichment and isolation using a magnetic device (permanent magnet or electromagnet). The labeled sample passes through a tube/channel within a magnetic field so the magnetic nano-particle labeled targets can be captured. Once the magnetic field is turned off, the captured targets can be released in a container. The labeling of the targets also can be performed in a device with soft magnetic collectors inside. Without magnetic activation, the device is just like a regular biological sample incubator. Thus the targets are labeled during the mixing and incubation. Once the device is placed in the magnetic field, the soft magnetic collectors are activated and the labeled target cells are isolated. After the washing process, the pure targets are released into the target collector by turning off the magnetic field with or without centrifugation. The magnet can be a permanent magnet or an electromagnet producing the magnetic field for targets to bind to the soft magnetic collectors in the device. The soft magnetic collectors can function as a magnet for capturing and releasing targets without the need of separation covers between magnet and target biological structures.
