ASTRONAUTS DO NOT HAVE A SIMPLE AND RELIABLE METHOD TO ACCURATELY AND IN REALTIME MONITOR THEIR HEALTH DURING MISSIONS. IFOS PROPOSES AN INNOVATIVE MINIATURIZED BLOOD MONITORING LABONACHIP TO DIRECTLY MONITOR ASTRONAUT HEALTH IN REALTIME. IFOS' INNOVATIVE SYSTEM COMPRISES A MINIATURIZED BIOSENSOR BASED ON PHOTONIC INTEGRATED CIRCUITS AND SENSITIVE FLUORESCENT ASSAY. WHILE IFOS' INITIAL FOCUS WILL BE ON MEASUREMENT OF TOTAL PROTEIN CONCENTRATION IN BLOOD IFOS WILL LEVERAGE AND BUILD UPON PIONEERING WORK DONE BY COLLABORATOR STANFORD UNIVERSITY TO ENABLE MULTIANALYTE SENSING. THE IMPLEMENTATION OF THE BLOOD MONITORING DEVICE ON GALLIUM ARSENIDE (GAAS) WILL ENABLING A FORM FACTOR OF 1 CUBIC INCH AT COMPETITIVE COST.
