摘要： A phase contrast quadrature interferometric method for determining the presence or absence of a target analyte in a sample. The method comprises using a laser beam having a wavelength λ and a waist wo to probe at least a portion of a substrate having a reflecting surface that has been exposed to the sample. The reflecting surface includes at least a first region having a layer of recognition molecules specific to the target analyte and a second region that does not include a layer of recognition molecules specific to the target analyte. The method further comprises measuring a time dependent intensity on a photodetector of a substantially only first quadrature at one of a pair of quadrature angles ⊖q of a reflected diffraction signal of the probe beam while probing the first region and the second region. An apparatus for phase-contrast quadrature interferometric detection of the presence or absence of a target molecule on a planar array, comprises a laser source for generating a probe beam. The apparatus includes a platform for receiving the planar array and a first optical train for directing the probe beam at the platform in a substantially surface normal manner. The apparatus also includes an objective lens having a first side and a second side and having a focal length, the objective lens being offset on the first side of the lens from the platform by a first distance approximately equal to the focal length. The apparatus further includes split photodetector means for measuring a first quadrature and a second quadrature in a signal resulting from reflection of the probe laser beam.

摘要： Method and apparatus for use with a probe beam and detector for detecting the presence of a target analyte in a sample. The apparatus includes a substrate; and a biolayer located on the substrate designed to react to target analyte when the sample is deposited on the biolayer. The substrate can be selected to substantially minimize reflectance by the substrate while substantially maintaining scattering by the target analyte. The substrate can be designed so waves reflected by the substrate are substantially in quadrature with waves scattered by target analyte; or so waves reflected by the substrate and scattered by target analyte interfere in the far field and directly create intensity modulation detectable by the detector. The biolayer can include a plurality of spots, and the spots can be grouped into unit cells having specific antibodies and non-specific antibodies for reacting with target analyte.
