In-orbit Characterization of a Lab-on-Chip Payload with Integrated Thin-Film Photosensors for Chemiluminescent Immunoassays aboard the AstroBio CubeSat Mission

Preliminary results of the in-orbit characterization of an analytical payload based on a lab-on-chip device with integrated thin-film photosensors relying on chemiluminescence immunoassay is presented. The paper addresses the characterization of the main components of the analytical system based on data acquired during the AstroBio CubeSat mission launched aboard the Vega-C maiden flight in summer 2022. In particular, the performances of the on-chip thin-film sensors and the lab-on-chip front-end readout electronics are reported in detail confirming the suitability of the proposed technology for space application.
