Patent ID: 6862398

Claim:
A sample delivery and sensing unit for directed molecular interaction during surface plasmon resonance analysis comprising: an electrically conductive surface plasmon resonance layer; an integrally formed surface plasmon resonance sensor in optic communication with the surface plasmon resonance layer, said sensor having a housing transparent to a given frequency of light, and, within said housing, a source of the given frequency of light directed onto said surface plasmon resonance layer and a photodetector array for receiving said given frequency of light reflected from said plasmon resonance detector; and a flow cell attached to the surface plasmon resonance layer, having a fluid path, said fluid path having an analyte detection chamber disposed along the fluid path, said analyte detection chamber having an interior region in fluidic communication with the surface plasmon resonance layer and having means for generation of a molecular interaction bias across the analyte detection chamber; wherein the molecular interaction bias is magnetic.
