Magnetic device with magnetic structure and micro-fluidic structure

A method of separating particles, the method comprising:

• receiving a fluid via an inlet of a micro-fluidic channel embedded in a multi-layer structure, wherein the fluid comprises different types of particles;
• applying, with a magnetic structure positioned about the micro-fluidic channel and embedded in the multi-layer structure, a magnetic field to the fluid in the micro-fluidic channel;
• and
• in response to applying the magnetic field, separating the different types of particles in the fluid into respective different channel portions of the micro-fluidic channel.

A magnetic device comprising:

• a micro-fluidic channel comprising an inlet arranged to receive a fluid that includes different types of particles;
• a magnetic structure comprising a patterned layer positioned about the micro-fluidic channel, the patterned layer comprising material configured to produce a magnetic field to cause the different types of particles in the fluid to be separated in the micro-fluidic channel, wherein the micro-fluidic channel and the magnetic structure are embedded in a multi-layer structure;
• and
• a conductive coil electrically connected to the patterned layer.
