  • Biosensor surface structures and methods
    Patent number: 7323347
    Abstract: A biosensor surface with a low density of ligand-carrying tether molecules on a base layer. Also, surface plasmon resonance (SPR) devices have the biosensor surface attached to a thin gold layer with backside angle-spread incident radiation for resonance excitation and reflective detection.

  • Surface plasmon resonance sensor having real-time referencing
    Patent number: 6943887
    Abstract: A disposable, portable, miniature surface plasmon resonance sensor (30) having real-time referencing capability in the presence of any interaction, without changing the sensing surface condition is disclosed herein. The sensor (30) includes an electromagnetic radiation source (32) which generates a beam of electromagnetic radiation (52) that passes through a liquid crystal switch that includes a polarizer, plates and liquid crystal material sandwiched between the plates. The liquid crystal switch is disposed between the source (32) and an array of detectors (48). The liquid crystal switch has the ability to switch between a first and a second state of polarized radiation such that it provides the transverse magnetic component of the electromagnetic radiation for detection of SPR on a target element and, in the alternative, provides the transverse electric component of the electromagnetic radiation to determine a reference signal for the sensor (30).
