Programmable electromagnetic array for molecule transport
First Claim
1. A device comprising:
- at least two electromagnetic elements each comprising a coil and a metallic core, wherein the metallic core is located at least partially within the coil,a controller that is adapted to control currents delivered to the two or more coils,wherein the device is capable of creating a magnetic field between adjacent electromagnetic elements wherein the magnetic field is capable of moving a magnetic particle in a fluid from the proximity of a first electromagnetic element to the proximity of a second adjacent electromagnetic element through the application of a current to at least one of the two adjacent electromagnetic elements, andan optical detector system capable of detecting a particle complex comprising a magnetic particle that is located in proximity to one of the two electromagnetic elements.

Abstract
An embodiment of the invention relates to a device comprising (1) an array of electromagnetic elements comprising coils, metal cores, and metal core heads, and (2) a controller that is adapted to control a current for one or more coils individually, to vary the current for said one or more coils individually, to reverse the current for one or more coils individually, and to generate a specific magnetic flux distribution and gradient across two or more coils; wherein the metal core head is at one end of the coil and the metal core head has a geometry to create a desired magnetic flux, intensity and gradient, in a region of interest between two adjacent coils; further wherein the device is functionally coupled to a fluidic device to concentrate and transport magnetic particles in a fluid without fluidic movement of the fluid.
