摘要： The present invention includes several methods for modifying the current processes of manufacturing optical sensing microplates that use continuous waveguide films to reduce/eliminate crosstalk between the biosensors that are incorporated within wells. The methods include (1) physically deteriorating/removing the waveguide film between individual biosensors; (2) chemically depositing highly absorbing materials within the waveguide film between individual biosensors; (3) patterning disordered (scattering) regions between the diffraction gratings that define individual biosensors; (4) using a specific mask and depositing individual patches of waveguide film, where each patch defines at least one biosensor. Each of these methods and several other methods described herein prevent the propagation of light between individual sensing regions, thereby eliminating optical crosstalk between the biosensors. The present invention also includes the resulting microplate.

摘要： An optical interrogation system and method are described herein that can interrogate a two-dimensional (2D) array of optical sensors (e.g., grating coupled waveguide sensors) located in a 2D specimen plate (e.g., microplate). In one embodiment, the optical interrogation system has a launch system which directs an array of light beams towards the array of sensors in the two-dimensional specimen plate. The optical interrogation system also has a receive system that includes a Keplerian beam expander (used in reverse as a beam condenser) which receives an array of light beams output from the array of sensors and directs each received light beam to a unique region on the detection plane of a small area detector (e.g., CCD camera). In addition, the optical interrogation system has a processor that analyzes changes in the position or shape of each detected light beam to determine if a binding event (bio-chemical interaction) or a mass transport (cell-based assay) occurred, or to determine the rate of binding (kinetics) that occurred on each sensor.

摘要： Optical interrogation systems and methods are described herein that are capable of measuring the angles (or changes in the angles) at which light reflects, transmits, scatters, or is emitted from an array of sensors or specimens that are distributed over a large area 2-dimensional array. In one embodiment of the present invention, the optical interrogation system has a far-field diffraction measurement configuration so it can simultaneously receive the light from sensors in all or a sub-section of a sensor array at a detector. In another embodiment of the present invention, the optical interrogation system incorporates an anamorphic optical receive system that enables parallel detection of angular responses from the sensors in the 2D array. In yet another embodiment of the present invention, the optical interrogation system incorporates an angular measurement system which measures the change in angular tilt of the sensor plane when the sensor array is moved or removed and then replaced in the measurement system. Several other embodiments of optical interrogation systems and methods are also described herein. A significant advantage of the present invention is that the system has no critical moving or scanning parts, which are frequently the source of measurement sensitivity limitations.

摘要： An optical interrogation system and a GCW sensor are described herein that are used to determine whether a biological substance (e.g., cell, molecule, protein, drug) is located in a sensing region of the GCW sensor. The optical interrogation system includes a light source, a polarization modulator and a detection system. The light source outputs a polarized light beam and the polarization modulator modulates the polarized light beam and outputs a polarization-modulated light beam. The GCW sensor receives and converts the polarization-modulated light beam into an amplitude modulated light beam that is directed towards the detection system. The detection system receives the amplitude modulated light beam and demodulates the received amplitude modulated light beam by responding to signals at a modulation frequency of the polarization-modulated light beam and ignoring noise affecting the signals outside the modulation frequency to detect a resonant condition (e.g., resonant angle, resonant wavelength). The detected resonant condition that has a one-to-one relationship with the refractive index of the superstrate containing the biological substance is analyzed to determine whether or not the biological substance is located in the sensing region of the GCW sensor.
