    Abstract: Systems and methods biochemically sense a concentration of a ligand using a sensor having a substrate having a metallic nanoparticle array formed onto a surface of the substrate. A light source is incident on the surface. A matrix is deposited over the nanoparticle array and contains a protein adapted to binding the ligand. A detector detects s-polarized and p-polarized light from the reflective surface. Spacing of nanoparticles in the array and wavelength of light are selected such that plasmon resonance occurs with an isotropic point such that ?s and ?p polarizations of the incident light result in substantially identical surface Plasmon resonance, wherein binding of the ligand to the protein shifts the resonance such that differences between the ?S and ?P polarizations give in a signal indicative of presence of the ligand.

    Abstract: A method of separating a target biological analyte from a mixture of substances in a fluid sample employs nonlinear magnetophoresis. Magnetic particles having the capacity to bind to the target analyte are contacted with the fluid sample so that the analyte is immobilized on the surface of at least some of the particles. The magnetic particles are provided adjacent an array of micromagnets patterned on a substrate so that the particles are attracted the micromagnets. The magnetic particles are then subjected to a traveling magnetic field operating at or above a frequency effective to sweep those particles not bound to analyte to an adjacent micromagnet. Those magnetic particles bound to analyte have a larger size or smaller magnetic moment that prevents them from being moved to adjacent micromagnets, thereby affording separation of the analyte.
