    摘要: The present invention includes a system and method that uses optical LID biosensors to monitor in real time agonist-induced GPCR signaling events within living cells. Particularly, the present invention includes a system and method for using an optical LID biosensor to screen compounds against a target GPCR within living cells based on the mass redistribution due to agonist-induced GPCR activation. In an extended embodiment, the present invention discloses different ways for self-referencing the optical LID biosensor to eliminate unwanted sensitivity to ambient temperature, pressure fluctuations, and other environmental changes. In yet another extended embodiment, the present invention discloses different ways for screening multiple GPCRs in a single type of cell or multiple GPCRs in multiple types of cells within a single medium solution. In still yet another extended embodiment, the present invention discloses different ways to confirm the physiological or pharmacological effect of a compound against a specific GPCR within living cells.

    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 are capable of generating light beams that have desired optical properties which are directed towards a specimen array. In one embodiment, the optical interrogation system includes a light source, a diffractive element and a collimating optic (e.g., simple lens(es), f-θ lens(es), segmented mirror, fiber array). The light source emits a light beam to the diffractive optic which receives the light beam and outputs an array of light beams to the collimating optic. The collimating optic receives and conditions the light beams emitted from the diffractive optic and then outputs the conditioned light beams which have desired optical properties towards a specimen array. Several other embodiments of the optical interrogation system are also described herein.
