Publication number: 20230190160Abstract: A system and method for collection and interpretation of data for determining impairment by intoxicant(s) in a subject at the point of collection utilizes of multiple sensors which may comprise both a live-cell assay in a disposable cartridge for determining the presence of intoxicant(s) and an eye scanner for determining vital signs and neurological state of the subject. The cartridge may be equipped to intake a sample, process it, and/or interact it with one or more eukaryotic cell-based biosensors. A cartridge may function as an optical interface to relay signals from the biosensors to a detector. The eye scanner may be equipped with optical sensors for the detecting both vital signs and neurological state. Each optical sensor may be spectrally filtered to identify a biomarker or set of biomarkers. Another method utilizes the eye scanner to train a model to identify additional biomarkers within the live-cell assay on a cartridge to increase the specificity for impairment by the primary analyte.Type: ApplicationFiled: November 23, 2022Publication date: June 22, 2023Inventors: Alexei Leonidovich Beresnev, Daniel Allen Cohen, Stefan Sandberg
