Abstract: A spectral reflectance imaging device for detecting nanoparticle exosome biomarker targets includes an illumination source that illuminates a substrate with a plurality of separate wavelengths of incoherent light. The substrate includes an oxide layer and a binding agent to selectively bind nanoparticle exosome biomarker targets to the substrate. An imaging device bindings the light reflected from or transmitted through the substrate and an image processing system detects the nanoparticle exosome biomarker targets a function of the change in reflective properties of the substrate.

Abstract: Presented herein are compositions, systems, and methods related to optical substrates that simultaneous (1) enhance a fluorescence signal emitted by a fluorophore and (2) enhance “contrast” signal that comprises scattered signal intensity over substrate reflectivity at a non-fluorescent wavelength. In certain embodiments, the optical substrate comprises a thin, transparent, dielectric layer. In alternative embodiments, the optical substrate comprises a stack of thin, transparent dielectric layers, for example, that is designed for both specific scattering enhancement and fluorescence enhancement.

Abstract: A system for analyzing one or more liquid samples includes a microwell plate including a plurality of rows of wells configured to store liquid samples, a sensor array that is moveable relative to the microwell plate along a first axis between a first position and a second position to allow a portion of the sensor array to be disposed within a first one of the plurality of rows of wells when the sensor array is in the second position, an objective, and one or more linear translation stages configured to move the microwell plate relative to the objective (i) along a second axis that is orthogonal to the first axis, (ii) along a third axis that is orthogonal to the first axis and the second axis, or (iii) both (i) and (ii).

Abstract: Stimulation of the central nervous system can be useful for treating neurological disorders. Wireless neurostimulating devices have the benefit that they can float in tissue and do not experience the sheering caused by tethering tension that connecting wires impose on the stimulators. An optically powered, logic controlled, CMOS microdevice that can decode telemetry data from an optical packet is a way of implementing wireless, addressable, microstimulators. Through the use of an optical packet, different devices can be addressed for stimulation, allowing spatially selective activation of neural tissue. The present invention, involves such a neural stimulation device, specifically an optically powered CMOS circuit that decodes telemetry data and determines whether it has been addressed.
