  • Publication number: 20140185051
    Abstract: An instrument comprises a semi-circular rail and a driving mechanism. The driving mechanism is attached to a light source mount and a detector mount, and both the light source mount and the detector mount are attached to the semi-circular rail with connectors. Each connector allows the light source mount and detector mount to slide along the rail. The synchronous movement of the light source mount and the detector mount changes the angle of incidence of a light beam from the light source with respect to the plane of the sample surface on the sample stage. An SPR analysis system includes an SPR analysis system control computer program having a graphical user interface and configured to control the operation of an SPR analysis apparatus. According to an embodiment, an SPR data analysis computer program includes an SPR microarray video viewer and a sensorgram generator responsive to the SPR video.

  • Publication number: 20120115748
    Abstract: An article, process, and method for surface plasmon resonance plates are described. A substrate is covered with a thin metal film onto which a second thin metal film is deposited. The surface of the second thin metal film is converted to the metal oxide which is used to covalently bond organosilanes to the surface. Reactive organosilanes containing terminal bonding groups are arranged in a plurality of spots that are surrounded by inert organosilanes. Biomolecule attachment to the binding group is detected or measured from surface plasmon signals from the first thin metal film.

  • Patent number: 7745143
    Abstract: A method of analyzing a sample comprising directing a beam of light to a spot on the surface of a microarray treated with the sample using a digital micromirror device, and observing the SPR spectral shift due to a chemical binding event. The digital micromirror device can be, for example, that used in Digital Light Processing (DLP). Such a device can selectively place a pixel of light onto a microarray such that each spot can be observed at millisecond intervals and the whole microarray can be sequentially scanned over a relatively short period. The SPR spectral shift for each spot can be measured as a function of time, thus producing SPR detection of molecular binding in an array format.
