▎ 摘　　要

NOVELTY - An analytical device comprises a detector unit capable of interfacing with an analytical unit and comprises detection surfaces capable of interacting with an ambient vapor phase and orifice for introducing a sample to be assayed; and a component for collecting the signal from the output. The detection surface comprises a nano-sensor element (NSE) layer between an input and an output. The input in contact with a base power source. The output is in communication with greater than or equal to 1 data collector. The NSE layer is associated with a selection component with selection specificity for greater than or equal to 1 compounds of interest. The selection component when in contact with or in close proximity to a target compound possibly present in the vapor phase selectively alters signal to the output. USE - An analytical device used for obtaining a data set for aiding diagnosing disease or for providing a disease status or health status of an individual providing a biosample (all claimed). ADVANTAGE - The device assays non-invasively obtained biosamples in real-time to output a volatile organic compound (VOC) based signature that, when correlated with data in a disease signature library, identifies diseases associated with the sample. The device optimizes the capture, classification and pattern recognition necessary for identifying a unique VOC signature from that biosample. The device improves patient experience and outcomes, reduces the number and extent of invasive medical procedures and reduces medical treatment costs through the early identification and detection of disease. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for obtaining a data set for aiding diagnosing disease or for providing a disease status or health status of an individual providing a biosample, which involves (a) providing a sample to an analytical device; (b) analyzing the sample using the device; (c) collecting data outputted from sensors within the device; (d) maintaining a file of data outputted; (e) analyzing, characterizing or storing data outputted; and (f) incorporating result of (e) into a data set. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the apparatus.
