摘要： Some embodiments of the present disclosure are directed to systems and methods for separating, directing, and/or extracting a target molecule from a mix of molecules and may comprise a plurality of non-magnetic beads suspended in a ferro fluid, where the non-magnetic beads may be functionalized with at least one predetermined first molecule configured to bind with a target particle. A microfluidic device may be included which may comprise at least one microfluidic channel, the device configured to dynamically and/or statically receive an amount of the mix. Magnetic field means may be included and may be configured to apply a magnetic field to at least a portion of the at least one channel to exert an indirect force on the non-magnetic heads in the ferro fluid mix, and separate the non-magnetic beads from the ferrofluid. The beads may then be directed to at least one receptor region. At least one outlet may be provided which is arranged to be in communication with the at least one microfluidic channel, the at least one outlet may be configured to receive and extract the separated non-magnetic beads from the ferrofluid.

摘要： Magnetic cell levitation and cell monitoring systems and methods are disclosed. A method for separating a heterogeneous population of cells is performed by placing a microcapillary channel containing the heterogeneous population of cells in a magnetically-responsive medium in the disclosed levitation system and separating the cells by balancing magnetic and corrected gravitational forces on the individual cells. A levitation system is also disclosed, having a microscope on which the microcapillary channel is placed and a set of two magnets between which the microcapillary channel is placed. Additionally, a method for monitoring cellular processes in real-time using the levitation system is disclosed.

摘要： The present invention includes a method of controlling an oil spill through introduction of a plurality of magnetizable particles into the oil spill in an amount sufficient to form a colloidal mixture. An absorbent is, also introduced into the oil spill to form an absorbent mixture. A magnetic field can be applied to the system to move, manipulate, or otherwise control the absorbent mixture in response to movement of the magnetic field.

摘要： One embodiment relates to a system and method by which the magnetic susceptibility of a fluid is changed to separate the fluid according to differences in magnetic susceptibility. According to one embodiment, a fluid separation system and method can efficiently separate materials contained in a fluid according to magnetic susceptibility, without damage such as hemolysis or without changes in the types or concentrations of marker proteins in plasma.

摘要： Devices, methods, and systems are provided for extracting particles from a ferrofluid and for rapid affinity measurements. Such systems may comprise a fluidic channel or chamber configured to include a ferrofluid having a plurality of target particles and background particles. The systems may include a capture region configured to capture at least a portion of the plurality of target particles. In addition, the systems include a first magnetic field generator and a second magnetic field generator. The first magnetic field generator may be arranged proximate to the fluidic channel, the first magnetic field generator being configured to generate a first magnetic field configured to direct the plurality of target particles towards the capture region. The second magnetic field generator can be arranged to be proximate to the capture region, and is further configured to generate an affinity thresholding magnetic field configured to remove background particles from the capture region.
