Abstract: The present application is generally directed to systems, methods, and devices for diagnostics for sensing and/or identifying pathogens, genomic materials, proteins, and/or other small molecules or biomarkers. In some implementations, a small footprint low cost device provides rapid and robust sensing and identification. Such a device may utilize microfluidics, biochemistry, and electronics to detect one or more targets at once in the field and closer to or at the point of care.

In some implementations, the systems and methods herein implement a reader device, an assay cartridge, and a mobile or external device configured to receive abiological sample, test the biological sample, and provide test results to a patient or user associated with the patient. The test results may be packaged with additional information, including symptoms suffered by the patient, a diagnosis, and follow-up instructions.

Abstract: Embodiments as disclosed herein may include a sensor including a luminophor exposed to a fluid flow path. The luminophor may emit light in response to illumination by an excitation light source. The magnitude of light emitted by the luminophor in response to illumination may be determined. It can be determined if this magnitude is within a threshold of the baseline magnitude and an alarm state set based on this determination. This alarm state may indicate that the luminophor has reached an end-of-life state or otherwise should be replaced.

Abstract: Embodiments of a dissolved oxygen sensor are disclosed herein. Embodiments as disclosed herein may include a window of optically transparent material disposed in an opening in a fluid flow path, where a luminophor is attached to the side of the window exposed to the fluid in the flow path. An optical probe may be disposed opposite the window from the fluid flow path on an axis at an angle to the window fluid flow path. The optical probe includes an excitation light source for illumination of the luminophor and a reference light source. An optical reception guide is configured to conduct light from the luminophor to a photodiode adjacent to the end of the optical reception guide distal the window when the luminophor is illuminated by the excitation light source. The optical probe is configured to determine a measure of oxygen concentration of the fluid in the flow path.
