This extraction step will be performed using a technology recently pioneered by our team: a microfluidic and magnetic fluidized bed. Fluidized-beds are commonly used to enhance surface interactions in a solid/liquid mixture, with high stirring and low backpressure. Our team developed a completely new concept of micro-fluidized beds based on magnetic micro-particles in equilibrium between flow-induced drag forces and magnetic forces [1]. This system already showed unprecedented efficiency for solid phase extraction and was successfully applied for bacteria analysis [2] and proteins preconcentration [3].
