Nano DiagnosiX

Nano DiagnosiX was a U.S.-based biotech/diagnostics startup developing portable point-of-care diagnostic devices for early disease detection. Its core technology, FemtoSpot, used nanostructure-based field-effect transistor biosensor chips designed to detect biomarkers, antigens, antibodies, and DNA at very low concentrations from small samples. The company positioned the platform as a handheld, lab-quality testing system with potential applications in infectious disease screening, including COVID-19, as well as cardiovascular biomarker detection. Available evidence suggests Nano DiagnosiX remained an early-stage diagnostics platform company rather than a therapeutic drug developer. More recent company-tracking sources indicate the business is no longer active.
