    Abstract: In accordance with an embodiment of the invention, there is provided a method for: a) high-throughput, multiplexed, affinity-based separation of proteins - especially low abundance proteins - from complex biological mixtures such as serum; and b) high- throughput, multiplexed, affinity-based separation of cells - especially rare cells - from complex biological mixtures such as blood or blood fractions. The separation of proteins or cells is achieved based on differential binding to affinity-capture beads of different sizes and then sorting the protein-bound or cell-bound beads using the concept of centrifugal-induced Dean migration in a spiral microfluidic device. This method enables continuous-flow, high throughput affinity-separation of milligram-scale protein samples or millions of cells in minutes after binding. This is particularly applicable to the isolation of antigen-specific antibodies from polyclonal sera and antigen-specific immune cells or circulating tumor cells from blood, both of which are otherwise highly labor-intensive and expensive to perform.

    Abstract: In one aspect, the inventive concepts disclosed herein are directed to a sensor assembly which contains a first planar substrate and a second planar substrate which respectively support opposing sensor arrays and contains an integrated flow path extending between the first and second substrates. Sensor assembly contains a first planar substrate having a base layer, and a conductive layer formed on a first planar surface of the base layer. Base layer may be made from, for example, ceramic, polymer, foil, or any other type of material known to someone of ordinary skill in the art. Conductive layer contains at least at least two electrically isolated electrical contacts made, for example, using a thick film approach (e.g., screen printing, rotogravure, pad printing, stenciling conductive material such as carbon, Cu, Pt, Pd, Au, and/or Nanotubes, etc.) or a thin firm approach (e.g., by sputtering, thermal spraying, and/or cold spraying conductive material).

    Abstract: A method of separating one or more binding molecules that are specifically bound to one or more binding targets from a mixture of bound and unbound molecules includes introducing the mixture into at least one inlet of a microfluidic device at a sample flow rate. The microfluidic device includes at least one curved channel, wherein each curved channel has a length, a radius, and a cross-section of a height and a width defining an aspect ratio adapted to isolate the one or more molecules bound to the binding target along portions of the cross-section of the channel based on size. Bound molecules flow along a radially innermost portion of the channel to a first outlet, and unbound molecules flow along one or more other portions of the channel to at least one other outlet, thereby separating the one or more binding molecules that are specifically bound to the one or more binding targets from the mixture of bound and unbound molecules.
